fileExists() Netscript Function

fileExists(filename[, hostname/ip])
  • filename (string) – Filename of file to check
  • hostname/ip (string) – 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

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.


fileExists("foo.script", "foodnstuff");

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.
