read() Netscript Function
|

|
|
=========================
|

|
|
|

|
|
.. js:function:: read(port/fn)
|
||
|
|
|
||
|
|
:param string/number port/fn: Port or text file to read from

|
|
||
|
|
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.
