|
|
|

|
|
```
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Description |
|
|
| --- | --- | --- |
|
|
| filename | string | Filename of file to check. |
|
|
| host | string | Host of target server. This is optional. If it is not specified then the function will use the current server as the target server. |

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.
|
|
|
|
## Example 1
|
|
|
|
|
|
```ts
|
|
// NS1:
|
|
//The function call will return true if the script named foo.script exists on the foodnstuff server, and false otherwise.
|
|
fileExists("foo.script", "foodnstuff");
|
|
|
|
//The function call will return true if the current server contains the FTPCrack.exe program, and false otherwise.
|
|
fileExists("ftpcrack.exe");
|
|
```

## Example 2
|
|
|
|
|
|
```ts
|
|
// NS2:
|
|
// The function call will return true if the script named foo.script exists on the foodnstuff server, and false otherwise.
|
|
ns.fileExists("foo.script", "foodnstuff");
|
|
|
|
// The function call will return true if the current server contains the FTPCrack.exe program, and false otherwise.
|
|
ns.fileExists("ftpcrack.exe");
