Netscript Basic Functions
|
|
=========================
|
|
|
|
This page contains the complete documentation for all functions that are available in Netscript.
|
|
This includes information such as function signatures, what they do, and their return values.
|
|
|
|
At the end is also a section that describes how to define your own functions in Netscript.
|
|
|
|
hack
|
|
^^^^
|
|
|
|
.. js:function:: hack(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server to hack
|
|
:returns: The amount of money stolen if the hack is successful, and zero otherwise
|
|
:RAM cost: 0.1 GB
|
|
|
|
Function that is used to try and hack servers to steal money and gain hacking experience. The runtime for this command depends
|
|
on your hacking level and the target server's security level. In order to hack a server you must first gain root access
|
|
to that server and also have the required hacking level.
|
|
|
|
A script can hack a server from anywhere. It does not need to be running on the same server to hack that server. For example,
|
|
you can create a script that hacks the 'foodnstuff' server and run that script on any server in the game.
|
|
|
|
A successful hack() on a server will raise that server's security level by 0.002.
|
|
|
|
Example::
|
|
|
|
hack("foodnstuff");
|
|
hack("10.1.2.3");
|
|
|
|
grow
|
|
^^^^
|
|
|
|
.. js:function:: grow(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server to grow
|
|
:returns: The number by which the money on the server was multiplied for the growth
|
|
:RAM cost: 0.15 GB
|
|
|
|
Use your hacking skills to increase the amount of money available on a server. The runtime for this command depends on your hacking
|
|
level and the target server's security level. When grow() completes, the money available on a target server will be increased by a
|
|
certain, fixed percentage. This percentage is determined by the target server's growth rate (which varies between servers) and security level.
|
|
Generally, higher-level servers have higher growth rates. The getServerGrowth() function can be used to obtain a server's growth rate.
|
|
|
|
Like hack(), grow() can be called on any server, regardless of where the script is running. The grow() command requires
|
|
root access to the target server, but there is no required hacking level to run the command. It also raises the security level
|
|
of the target server by 0.004.
|
|
|
|
Example::
|
|
|
|
grow("foodnstuff");
|
|
|
|
weaken
|
|
^^^^^^
|
|
|
|
.. js:function:: weaken(hostname/ip)
|
|
|
|
:param string hostname.ip: IP or hostname of the target server to weaken
|
|
:returns: The amount by which the target server's security level was decreased. This is equivalent to 0.05 multiplied
|
|
by the number of script threads
|
|
:RAM cost: 0.15 GB
|
|
|
|
Use your hacking skills to attack a server's security, lowering the server's security level. The runtime for this command
|
|
depends on your hacking level and the target server's security level. This function lowers the security level of the target
|
|
server by 0.05.
|
|
|
|
Like hack() and grow(), weaken() can be called on any server, regardless of where the script is running. This command requires
|
|
root access to the target server, but there is no required hacking level to run the command.
|
|
|
|
Example::
|
|
|
|
weaken("foodnstuff");
|
|
|
|
sleep
|
|
^^^^^
|
|
|
|
.. js:function:: sleep(n)
|
|
|
|
:param number n: Number of milliseconds to sleep
|
|
:RAM cost: 0 GB
|
|
|
|
Suspends the script for n milliseconds.
|
|
|
|
print
|
|
^^^^^
|
|
|
|
.. js:function:: print(x)
|
|
|
|
:param x: Value to be printed
|
|
:RAM cost: 0 GB
|
|
|
|
Prints a value or a variable to the script's logs.
|
|
|
|
tprint
|
|
^^^^^^
|
|
|
|
.. js:function:: tprint(x)
|
|
|
|
:param x: Value to be printed
|
|
:RAM cost: 0 GB
|
|
|
|
Prints a value or a variable to the Terminal
|
|
|
|
clearLog
|
|
^^^^^^^^
|
|
|
|
.. js:function:: clearLog()
|
|
|
|
:RAM cost: 0 GB
|
|
|
|
Clears the script's logs
|
|
|
|
disableLog
|
|
^^^^^^^^^^
|
|
|
|
.. js:function:: disableLog(fn)
|
|
|
|
:param string fn: Name of function for which to disable logging
|
|
:RAM cost: 0 GB
|
|
|
|
Disables logging for the given function. Logging can be disabled for
|
|
all functions by passing 'ALL' as the argument.
|
|
|
|
Note that this does not completely remove all logging functionality.
|
|
This only stops a function from logging
|
|
when the function is successful. If the function fails, it will still log the reason for failure.
|
|
|
|
Notable functions that cannot have their logs disabled: run, exec, exit
|
|
|
|
enableLog
|
|
^^^^^^^^^
|
|
|
|
.. js:function:: enableLog(fn)
|
|
|
|
:param string fn: Name of function for which to enable logging
|
|
:RAM cost: 0 GB
|
|
|
|
Re-enables logging for the given function. If 'ALL' is passed into this function
|
|
as an argument, then it will revert the effects of disableLog('ALL')
|
|
|
|
isLogEnabled
|
|
^^^^^^^^^^^^
|
|
|
|
.. js:function:: isLogEnabled(fn)
|
|
|
|
:param string fn: Name of function to check
|
|
:RAM cost: 0 GB
|
|
|
|
Returns a boolean indicating whether or not logging is enabled for that
|
|
function (or 'ALL')
|
|
|
|
getScriptLogs
|
|
^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getScriptLogs([fn], [hostname/ip=current ip], [args...])
|
|
|
|
:param string fn: Optional. Filename of script to get logs from.
|
|
:param string ip: Optional. IP or hostname of the server that the script is on
|
|
:param args...: Arguments to identify which scripts to get logs for
|
|
:RAM cost: 0 GB
|
|
|
|
Returns a script's logs. The logs are returned as an array, where each
|
|
line is an element in the array. The most recently logged line is at the
|
|
end of the array.
|
|
|
|
Note that there is a maximum number of lines that a script stores in its logs.
|
|
This is configurable in the game's options.
|
|
|
|
If the function is called with no arguments, it will return the current script's logs.
|
|
|
|
Otherwise, the `fn`, `hostname/ip,` and `args...` arguments can be used to get the logs
|
|
from another script. Remember that scripts are uniquely identified by both
|
|
their names and arguments.
|
|
|
|
Examples::
|
|
|
|
// Get logs from foo.script on the current server that was run with no args
|
|
getScriptLogs("foo.script");
|
|
|
|
// Get logs from foo.script on the foodnstuff server that was run with no args
|
|
getScriptLogs("foo.script", "foodnstuff");
|
|
|
|
// Get logs from foo.script on the foodnstuff server that was run with the arguments [1, "test"]
|
|
getScriptLogs("foo.script", "foodnstuff", 1, "test");
|
|
|
|
scan
|
|
^^^^
|
|
|
|
.. js:function:: scan(hostname/ip=current ip[, hostnames=true])
|
|
|
|
:param string hostname/ip: IP or hostname of the server to scan
|
|
:param boolean: Optional boolean specifying whether the function should output hostnames (if true) or IP addresses (if false)
|
|
:RAM cost: 0.2 GB
|
|
|
|
Returns an array containing the hostnames or IPs of all servers that are one node way from the specified target server. The
|
|
hostnames/IPs in the returned array are strings.
|
|
|
|
nuke
|
|
^^^^
|
|
|
|
.. js:function:: nuke(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server
|
|
:RAM cost: 0 GB

brutessh
|
|
^^^^^^^^
|
|
|
|
.. js:function:: brutessh(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server
|
|
:RAM cost: 0 GB
|
|
|
|
Runs the BruteSSH.exe program on the target server. BruteSSH.exe must exist on your home computer.

|
|
|
ftpcrack
|
|
^^^^^^^^
|
|

|
|
Runs the FTPCrack.exe program on the target server. FTPCrack.exe must exist on your home computer.
|
|
|
|
Example::
|
|
|
|
ftpcrack("foodnstuff");
|
|
|
|
relaysmtp
|
|
^^^^^^^^^
|
|
|
|
.. js:function:: relaysmtp(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server
|
|
:RAM cost: 0 GB
|
|
|
|

|
|
|
httpworm
|
|
^^^^^^^^
|
|
|
|
.. js:function:: httpworm(hostname/ip)

|
|
|
|
Example::
|
|
|
|
httpworm("foodnstuff");
|
|
|
|
sqlinject
|
|
^^^^^^^^^
|
|
|
|
.. js:function:: sqlinject(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the target server
|
|
:RAM cost: 0 GB
|
|
|
|
Runs the SQLInject.exe program on the target server. SQLInject.exe must exist on your home computer.
|
|
|
|
Example::
|
|
|
|
sqlinject("foodnstuff");
|
|
|
|
run
|
|
^^^
|
|
|
|
.. js:function:: run(script, [numThreads=1], [args...])
|
|
|
|
:param string script: Filename of script to run
|
|
:param number numThreads: Optional thread count for new script. Set to 1 by default. Will be rounded to nearest integer
|
|
:param args...:
|
|
Additional arguments to pass into the new script that is being run. Note that if any arguments are being
|
|
passed into the new script, then the second argument *numThreads* must be filled in with a value.
|
|
:RAM cost: 1 GB
|
|
|
|
Run a script as a separate process. This function can only be used to run scripts located on the current server (the server
|
|
running the script that calls this function).
|
|
|
|
Returns true if the script is successfully started, and false otherwise. Requires a significant amount of RAM to run this
|
|
command.
|
|
|
|
The simplest way to use the *run* command is to call it with just the script name. The following example will run
|
|
'foo.script' single-threaded with no arguments::
|
|
|
|
run("foo.script");
|
|
|
|
The following example will run 'foo.script' but with 5 threads instead of single-threaded::
|
|
|
|
run("foo.script", 5);
|
|
|
|
This next example will run 'foo.script' single-threaded, and will pass the string 'foodnstuff' into the script
|
|
as an argument::
|
|
|
|
run("foo.script", 1, 'foodnstuff');
|
|
|
|
exec
|
|
^^^^
|
|
|
|
.. js:function:: exec(script, hostname/ip, [numThreads=1], [args...])
|
|
|
|
:param string script: Filename of script to execute
|
|
:param string hostname/ip: IP or hostname of the 'target server' on which to execute the script
|
|
:param number numThreads: Optional thread count for new script. Set to 1 by default. Will be rounded to nearest integer
|
|
:param args...:
|
|
Additional arguments to pass into the new script that is being run. Note that if any arguments are being
|
|
passed into the new script, then the third argument *numThreads* must be filled in with a value.
|
|
:RAM cost: 1.3 GB
|
|
|
|
Run a script as a separate process on a specified server. This is similar to the *run* function except
|
|
that it can be used to run a script on any server, instead of just the current server.
|
|
|
|
Returns true if the script is successfully started, and false otherwise.
|
|
|
|
The simplest way to use the *exec* command is to call it with just the script name and the target server.
|
|
The following example will try to run *generic-hack.script* on the *foodnstuff* server::
|
|
|
|
exec("generic-hack.script", "foodnstuff");
|
|
|
|
The following example will try to run the script *generic-hack.script* on the *joesguns* server with 10 threads::
|
|
|
|
exec("generic-hack.script", "joesguns", 10);
|
|
|
|
This last example will try to run the script *foo.script* on the *foodnstuff* server with 5 threads. It will also pass
|
|
the number 1 and the string "test" in as arguments to the script::
|
|
|
|
exec("foo.script", "foodnstuff", 5, 1, "test");
|
|
|
|
spawn
|
|
^^^^^
|
|
|
|
.. js:function:: spawn(script, numThreads, [args...])
|
|
|
|
:param string script: Filename of script to execute
|
|
:param number numThreads: Number of threads to spawn new script with. Will be rounded to nearest integer
|
|
:param args...:
|
|
Additional arguments to pass into the new script that is being run.
|
|
:RAM cost: 2 GB
|
|
|
|
Terminates the current script, and then after a delay of about 20 seconds it will execute the newly-specified script.
|
|
The purpose of this function is to execute a new script without being constrained by the RAM usage of the current one.
|
|
This function can only be used to run scripts on the local server.
|
|
|
|
Because this function immediately terminates the script, it does not have a return value.
|
|
|
|
The following example will execute the script 'foo.script' with 10 threads and the arguments 'foodnstuff' and 90::
|
|
|
|
spawn('foo.script', 10, 'foodnstuff', 90);
|
|
|
|
kill
|
|
^^^^
|
|
|
|
.. js:function:: kill(script, hostname/ip, [args...])
|
|
|
|
:param string script: Filename of the script to kill
|
|
:param string hostname/ip: IP or hostname of the server on which to kill the script
|
|
:param args...: Arguments to identify which script to kill
|
|
:RAM cost: 0.5 GB
|
|
|
|
Kills the script on the target server specified by the script's name and arguments. Remember that scripts
|
|
are uniquely identified by both their name and arguments. For example, if *foo.script* is run with the argument 1, then this
|
|
is not the same as *foo.script* run with the argument 2, even though they have the same code.
|
|
|
|
If this function successfully kills the specified script, then it will return true. Otherwise, it will return false.
|
|
|
|
Examples:
|
|
|
|
The following example will try to kill a script named *foo.script* on the *foodnstuff* server that was ran with no arguments::
|
|
|
|
kill("foo.script", "foodnstuff");
|
|
|
|
The following will try to kill a script named *foo.script* on the current server that was ran with no arguments::
|
|
|
|
kill("foo.script", getHostname());
|
|
|
|
The following will try to kill a script named *foo.script* on the current server that was ran with the arguments 1 and "foodnstuff"::
|
|
|
|
kill("foo.script", getHostname(), 1, "foodnstuff");
|
|
|
|
killall
|
|
^^^^^^^
|
|
|
|
.. js:function:: killall(hostname/ip)
|
|
|
|
:param string hostname/ip: IP or hostname of the server on which to kill all scripts
|
|
:RAM cost: 0.5 GB
|
|
|
|
Kills all running scripts on the specified server. This function returns true if any scripts were killed, and
|
|
false otherwise. In other words, it will return true if there are any scripts running on the target server.
|
|
|
|
|
|
exit
|
|
^^^^
|
|
|
|
.. js:function:: exit()
|
|
|
|
:RAM cost: 0 GB
|
|
|
|
Terminates the current script immediately
|
|
|
|
scp
|
|
^^^
|
|
|
|
.. js:function:: scp(files, [source], destination)
|
|
|
|
:param string/array files: Filename or an array of filenames of script/literature files to copy
|
|
:param string source:
|
|
Hostname or IP of the source server, which is the server from which the file will be copied.
|
|
This argument is optional and if it's omitted the source will be the current server.
|
|
:param string destination: Hostname or IP of the destination server, which is the server to which the file will be copied.
|
|
:RAM cost: 0.6 GB
|
|
|
|
Copies a script or literature (.lit) file(s) to another server. The *files* argument can be either a string specifying a
|
|
single file to copy, or an array of strings specifying multiple files to copy.
|
|
|
|
Returns true if the script/literature file is successfully copied over and false otherwise. If the *files* argument is an array
|
|
then this function will return true if at least one of the files in the array is successfully copied.
|
|
|
|
Examples::
|
|
|
|
//Copies hack-template.script from the current server to foodnstuff
|
|
scp("hack-template.script", "foodnstuff");
|
|
|
|
//Copies foo.lit from the helios server to the home computer
|
|
scp("foo.lit", "helios", "home");
|
|
|
|
//Tries to copy three files from rothman-uni to home computer
|
|
files = ["foo1.lit", "foo2.script", "foo3.script"];
|
|
scp(files, "rothman-uni", "home");
|
|
|
|
ls
|
|
^^
|
|
|
|
.. js:function:: ls(hostname/ip, [grep])
|
|
|
|
:param string hostname/ip: Hostname or IP of the target server
|
|
:param string grep: a substring to search for in the filename
|
|
:RAM cost: 0 GB
|
|
|
|
Returns an array with the filenames of all files on the specified server (as strings). The returned array
|
|
is sorted in alphabetic order
|
|
|
|
ps
|
|
^^
|
|
|
|
.. js:function:: ps(hostname/ip=current ip)
|
|
|
|
:param string ip: Hostname or IP address of the target server.
|
|
If not specified, it will be the current server's IP by default
|
|
:RAM cost: 0 GB
|
|
|
|
Returns an array with general information about all scripts running on the specified
|
|
target server. The information for each server is given in an object with
|
|
the following structure::
|
|
|
|
{
|
|
filename: Script name,
|
|
threads: Number of threads script is running with,
|
|
args: Script's arguments
|
|
}
|
|
|
|
Example usage (using :doc:`netscriptjs`)::
|
|
|
|
export async function main(ns) {
|
|
const ps = ns.ps("home");
|
|
for (let i = 0; i < ps.length; ++i) {
|
|
ns.tprint(ps[i].filename + ' ' + ps[i].threads);
|
|
ns.tprint(ps[i].args);
|
|
}
|
|
}
|
|
|
|

^^^^^^^^^^^^^
|
|
|
|
.. js:function:: hasRootAccess(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of the target server
|
|
:RAM cost: 0.05 GB
|
|

|
purchaseCost: Player's hacknet purchase cost multiplier,
|
|
ramCost: Player's hacknet ram cost multiplier,
|
|
coreCost: Player's hacknet core cost multiplier,
|
|
levelCost: Player's hacknet level cost multiplier
|
|
}
|
|

getServerMoneyAvailable
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerMoneyAvailable(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns the amount of money available on a server. **Running this function on the home computer will return
|
|
the player's money.**
|
|
|
|
Example::
|
|
|
|
getServerMoneyAvailable("foodnstuff");
|
|
getServerMoneyAvailable("home"); //Returns player's money
|
|
|
|
getServerMaxMoney
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerMaxMoney(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns the maximum amount of money that can be available on a server
|
|
|
|
getServerGrowth
|
|
^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerGrowth(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns the server's instrinsic "growth parameter". This growth parameter is a number
|
|
between 1 and 100 that represents how quickly the server's money grows. This parameter affects the
|
|
percentage by which the server's money is increased when using the *grow()* function. A higher
|
|
growth parameter will result in a higher percentage increase from *grow()*.
|
|
|
|
getServerSecurityLevel
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerSecurityLevel(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|

getServerBaseSecurityLevel
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerBaseSecurityLevel(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns the base security level of the target server. This is the security level that the server starts out with.
|
|
This is different than *getServerSecurityLevel()* because *getServerSecurityLevel()* returns the current
|
|
security level of a server, which can constantly change due to *hack()*, *grow()*, and *weaken()*, calls on that
|
|
server. The base security level will stay the same until you reset by installing an Augmentation(s).
|
|
|
|
getServerMinSecurityLevel

|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerMinSecurityLevel(hostname/ip)

|
|
|
|
getServerRam
|
|
^^^^^^^^^^^^
|
|
|
|
.. js:function:: getServerRam(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns an array with two elements that gives information about a server's memory (RAM). The first
|
|
element in the array is the amount of RAM that the server has total (in GB). The second element in
|
|
the array is the amount of RAM that is currently being used on the server (in GB).
|
|
|
|
Example::
|
|
|
|
res = getServerRam("helios");
|
|
totalRam = res[0];
|
|
ramUsed = res[1];
|
|
|
|
serverExists
|
|
^^^^^^^^^^^^
|
|
|
|
.. js:function:: serverExists(hostname/ip)
|
|
|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns a boolean denoting whether or not the specified server exists
|
|
|
|
fileExists
|
|
^^^^^^^^^^
|
|
|
|
.. js:function:: fileExists(filename, [hostname/ip])
|
|
|
|
:param string filename: Filename of file to check
|
|
:param string hostname/ip:
|
|
Hostname or IP of target server. This is optional. If it is not specified then the
|
|
function will use the current server as the target server
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns a boolean indicating whether the specified file exists on the target server. The filename
|
|
for scripts is case-sensitive, but for other types of files it is not. For example, *fileExists("brutessh.exe")*
|
|
will work fine, even though the actual program is named "BruteSSH.exe".
|
|
|
|
If the *hostname/ip* argument is omitted, then the function will search through the current server (the server
|
|
running the script that calls this function) for the file.
|
|
|
|
Examples::
|
|
|
|
fileExists("foo.script", "foodnstuff");
|
|
fileExists("ftpcrack.exe");
|
|
|
|
The first example above will return true if the script named *foo.script* exists on the *foodnstuff* server, and false otherwise.
|
|
The second example above will return true if the current server contains the *FTPCrack.exe* program, and false otherwise.
|
|
|
|
isRunning
|
|
^^^^^^^^^
|
|
|
|
.. js:function:: isRunning(filename, hostname/ip, [args...])
|
|

|
|
:param string hostname/ip: Hostname or IP of target server
|
|
:param args...: Arguments to specify/identify which scripts to search for
|
|
:RAM cost: 0.1 GB
|
|
|
|
Returns a boolean indicating whether the specified script is running on the target server. Remember that a script is
|
|
uniquely identified by both its name and its arguments.
|
|
|
|
**Examples:**
|
|
|
|
In this first example below, the function call will return true if there is a script named *foo.script* with no arguments
|
|
running on the *foodnstuff* server, and false otherwise::
|
|
|
|
isRunning("foo.script", "foodnstuff");
|
|
|
|
In this second example below, the function call will return true if there is a script named *foo.script* with no arguments
|
|
running on the current server, and false otherwise::
|
|
|
|
isRunning("foo.script", getHostname());
|
|
|
|
In this next example below, the function call will return true if there is a script named *foo.script* running with the arguments
|
|
1, 5, and "test" (in that order) on the *joesguns* server, and false otherwise::
|
|
|
|
isRunning("foo.script", "joesguns", 1, 5, "test");

|
|
|
|
:param number ram: Amount of RAM of a potential purchased server. Must be a power of 2 (2, 4, 8, 16, etc.). Maximum value of 1048576 (2^20)
|
|
|
|
Returns the cost to purchase a server with the specified amount of *ram*.
|
|
|
|
Examples::
|
|
|
|
for (i = 1; i <= 20; i++) {

|
|
:param string hostname: Hostname of the purchased server
|
|
:param number ram: Amount of RAM of the purchased server. Must be a power of 2 (2, 4, 8, 16, etc.). Maximum value of 1048576 (2^20)
|
|
:RAM cost: 2.25 GB
|
|
|
|
Purchased a server with the specified hostname and amount of RAM.
|
|
|
|
The *hostname* argument can be any data type, but it will be converted to a string and have whitespace removed. Anything that resolves to an empty string will
|
|
cause the function to fail. If there is already a server with the specified hostname, then the function will automatically append
|
|
a number at the end of the *hostname* argument value until it finds a unique hostname. For example, if the script calls
|
|
*purchaseServer("foo", 4)* but a server named "foo" already exists, the it will automatically change the hostname to "foo-0". If there is already
|
|
a server with the hostname "foo-0", then it will change the hostname to "foo-1", and so on.
|
|
|
|
Note that there is a maximum limit to the amount of servers you can purchase.
|
|
|
|
Returns the hostname of the newly purchased server as a string. If the function fails to purchase a server, then it will return an
|
|
empty string. The function will fail if the arguments passed in are invalid, if the player does not have enough money to purchase
|
|
the specified server, or if the player has exceeded the maximum amount of servers.
|
|
|
|
Example::
|
|
|
|
ram = 64;
|
|
hn = "pserv-";
|
|
for (i = 0; i < 5; ++i) {
|
|
purchaseServer(hn + i, ram);
|
|
}

|
|
:RAM cost: 2.25 GB
|
|
|
|
Deletes one of your purchased servers, which is specified by its hostname.
|
|
|
|
The *hostname* argument can be any data type, but it will be converted to a string. Whitespace is automatically removed from
|
|
the string. This function will not delete a server that still has scripts running on it.
|
|
|
|
Returns true if successful, and false otherwise.
|
|
|
|
getPurchasedServers

|
|
:param string data: Data to write
|
|
:param string mode: Defines the write mode. Only valid when writing to text files or scripts.
|
|
:RAM cost: 1 GB
|
|
|
|
This function can be used to either write data to a port, a text file (.txt), or a script (.script, .js, .ns)
|
|
|
|
If the first argument is a number between 1 and 20, then it specifies a port and this function will write *data* to that port. Read
|
|
about how :ref:`netscript_ports` work here. The third argument, *mode*, is not used
|
|
when writing to a port.
|
|
|
|
If the first argument is a string, then it specifies the name of a text file or script and this function will write *data* to that text file/script. If the
|
|
specified text file/script does not exist, then it will be created. The third argument *mode*, defines how the data will be written. If *mode*
|
|
is set to "w", then the data is written in "write" mode which means that it will overwrite all existing data on the text file/script. If *mode* is set to
|
|
any other value then the data will be written in "append" mode which means that the data will be added at the end of the file.
|
|
|

:RAM cost: 1 GB
|
|
|
|
This function is used to read data from a port, a text file (.txt), or a script (.script, .js, .ns)
|
|
|
|
If the argument *port/fn* is a number between 1 and 20, then it specifies a port and it will read data from that port. Read
|
|
about how :ref:`netscript_ports` work here. A port is a serialized queue. This function
|
|
will remove the first element from that queue and return it. If the queue is empty, then the string "NULL PORT DATA" will be returned.
|
|
|
|
If the argument *port/fn* is a string, then it specifies the name of a text file or script and this function will return the data in the specified text file/script. If
|
|
the text file does not exist, an empty string will be returned.

|
|
|
This function is used to clear data in a `Netscript Ports <http://bitburner.wikia.com/wiki/Netscript_Ports>`_ or a text file.
|
|
|
|
If the *port/fn* argument is a number between 1 and 20, then it specifies a port and will clear it (deleting all data from the underlying queue).
|
|
|
|
If the *port/fn* argument is a string, then it specifies the name of a text file (.txt) and will delete all data from that text file.

:RAM cost: 0.1 GB
|
|
|
|
Returns the amount of income the specified script generates while online (when the game is open, does not apply for offline income).
|
|
Remember that a script is uniquely identified by both its name and its arguments. So for example if you ran a script with the arguments
|

"foodnstuff" and "5" then in order to use this function to get that script's income you must specify those same arguments in the same order
|
|
in this function call.
|
|

This function can also be called with no arguments. If called with no arguments, then this function will return an array of two values. The
|
|
first value is the total income ($ / second) of all of your active scripts (scripts that are currently running on any server). The second value
|
|
is the total income ($ / second) that you've earned from scripts since you last installed Augmentations.

prompt
|
|
^^^^^^
|
|
|
|
.. js:function:: prompt(txt)
|
|
|
|
:param string txt: Text to appear in the prompt dialog box
|
|
:RAM cost: 0 GB
|
|
|
|
Prompts the player with a dialog box with two options: "Yes" and "No". This function will return true if the player click "Yes" and
|
|
false if the player clicks "No". The script's execution is halted until the player selects one of the options.
|
|
|
|
wget
|
|
^^^^
|
|
|
|
.. js:function:: wget(url, target[, hostname/ip=current ip])
|
|
|
|
:param string url: URL to pull data from
|
|
:param string target: Filename to write data to. Must be script or text file
|
|
:param string ip: Optional hostname/ip of server for target file.
|
|
:RAM cost: 0 GB
|
|
|
|
Retrieves data from a URL and downloads it to a file on the specified server. The data can only
|
|
be downloaded to a script (.script, .ns, .js) or a text file (.txt). If the file already exists,
|
|
it will be overwritten by this command.
|
|
|
|
Note that it will not be possible to download data from many websites because they do not allow
|
|
cross-origin resource sharing (CORS). Example::
|
|
|
|
wget("https://raw.githubusercontent.com/danielyxie/bitburner/master/README.md", "game_readme.txt");
|
|
|
|
**IMPORTANT:** This is an asynchronous function that returns a Promise. The Promise's resolved
|
|
value will be a boolean indicating whether or not the data was successfully
|
|
retrieved from the URL. Because the function is async and returns a Promise,
|
|
it is recommended you use :code:`wget` in :ref:`netscriptjs`.
|
|
|
|
In NetscriptJS, you must preface any call to
|
|
:code:`wget` with the :code:`await` keyword (like you would :code:`hack` or :code:`sleep`).
|
|
|
|
:code:`wget` will still work in :ref:`netscript1`, but the functions execution will not
|
|
be synchronous (i.e. it may not execute when you expect/want it to). Furthermore, since Promises are not
|
|
supported in ES5, you will not be able to process the returned value of :code:`wget` in
|
|
Netscript 1.0.
