in reply to Expect command output parser sub

This is brilliant!!!! Thank you so much for this.. I've been fooling around with this issue for over a year and never found anything satisfactory.

Here's what I was using so far... it does the job..but there was a need to match for a pattern anyway...

$sshMTT1->clear_accum(); $sshMTT1->expect(10,[qr/\$[\s]*/=> sub {$sshMTT1->send("grep <<<<<<*PA +TTERN>*>>>>");}]); @Output = $sshMTT1->expect(5); $sshMTT1->send("\cC"); $exactOutput = $Output[3]; $exactOutput =~ tr/\cM//d;

The variable $exactOutput had more or less the value I was looking for and I used to pattern match on this variable... Primitive.. compared to the solution here!!!

    This subroutine fails to execute the command if the executed command isn't supposed to return any value ( for example the cd command or mkdir command.

    For example if we try to execute the cd <XYZ_Directory> command using this subroutine, the directory change doesn't happen at all.

    Any help to make it fucntional for such commands is welcome

      I would say its impossible so don't use it on such commands, or append ";pwd" so they do print output
