Welcome suneet17,

I have a few to questions pose in response first:-
  • Is this homework/assignment? There are specific forums for these.
  • What have you tried so far? Please paste this in CODE tags.
  • What output/errors do you get?
  • What OS and version are you using?
  • What are your preferred tools you are calling this in with? (C, shell, perl, awk, etc.)
  • What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.
Is there a reason not to just use something like ssh $user@$server df > $local_output_file?


We're all here to learn and getting the relevant information will help us all.


Thanks, in advance,
Robin

NAME
Test::Expect - Automated driving and testing of terminal-based programs SYNOPSIS
# in a t/*.t file: use Test::Expect; use Test::More tests => 13; expect_run( command => "perl testme.pl", prompt => 'testme: ', quit => 'quit', ); expect("ping", "pong", "expect"); expect_send("ping", "expect_send"); expect_is("* Hi there, to testme", "expect_is"); expect_like(qr/Hi there, to testme/, "expect_like"); DESCRIPTION
Test::Expect is a module for automated driving and testing of terminal-based programs. It is handy for testing interactive programs which have a prompt, and is based on the same concepts as the Tcl Expect tool. As in Expect::Simple, the Expect object is made available for tweaking. Test::Expect is intended for use in a test script. SUBROUTINES
expect_run The expect_run subroutine sets up Test::Expect. You must pass in the interactive program to run, what the prompt of the program is, and which command quits the program: expect_run( command => "perl testme.pl", prompt => 'testme: ', quit => 'quit', ); expect The expect subroutine is the catch all subroutine. You pass in the command, the expected output of the subroutine and an optional comment. expect("ping", "pong", "expect"); expect_send The expect_send subroutine sends a command to the program. You pass in the command and an optional comment. expect_send("ping", "expect_send"); expect_is The expect_is subroutine tests the output of the program like Test::More's is. It has an optional comment: expect_is("* Hi there, to testme", "expect_is"); expect_like The expect_like subroutine tests the output of the program like Test::More's like. It has an optional comment: expect_like(qr/Hi there, to testme/, "expect_like"); expect_handle This returns the Expect object. expect_quit Closes the Expect handle. SEE ALSO
