Calling bash script inside the Perl Script with system command"

Question

I have a basic shell script like this;

#!/usr/bin/bash
echo "Openning ssh connection to remote host "$2" for "$1" user and finding the archive directory "$3""
ssh "$1"@"$2" find "$3"

I have another perl script named with Archive.pl in that script we are connecting remote server with Telnet connection. I want to call my script inside this Perl script to use other modules of Perl script. I'm trying that command but it doesn't work.

system("Connector.sh",$arg1,$arg2,$arg3);

Any ideas to do that ?

I need to do it inside the Perl script. I'm not trying to work on the console "sh script.sh". Because in Perl script there are other modules which i wanted to work on. — Hayra

Is it really valid to nest quotes like that? echo "Opening ... "$2" for "$1" ...."$3""? — TLP

You can skip the shell script, and just put this in your Perl script.

print qq(Opening ssh connection to remote host "$arg2" for "$arg1" user and finding the archive directory "$arg3");
system("ssh", "$arg1\@$arg2", "find", $arg3)

ssh: picroot: temporary name resolution failure. I'm getting that error

What is picroot? Does the ssh connection work outside your Perl script?

Hayra Over a year ago

picroot is username. Yes i can easily connect via console or my bash script.

See my edit; I forgot to switch to the correct variables for the call to system. Does that help?

You forgot to escape the @ sign, so @$arg2 was interpolated to the empty string, which made the ssh fail. Since you did not use warnings, you were not warned about this critical failure. Lesson is: always, always, always use use strict; use warnings;.
