Re: Calling an executable and entering login credentials

[zentara]

I don't know exactly how Sametime expects to get it's login, can you be more specific what the program does? Does it output a prompt, like Login:? Usually to interact with a program, the Expect module is usually recommended, google for perl Expect for sample code.

In a very simple situation, you may be able to get by with IPC::Open3, which opens the program, and gives you pipes to write to, and read from, the executable.

A simple example:

#!/usr/bin/perl 
use warnings;
use strict;
use IPC::Open3;

$|=1;

# you would run Sametime here, instead of bash
my $pid=open3(\*IN,\*OUT, \*ERR , '/bin/bash');

# set \*ERR to 0 to send STDERR to STDOUT
#  

# in your case, print the login name here
my $cmd = 'date';

#send cmd to bash
print IN "$cmd\n";

my $result = <OUT>;
print $result;
