RajNaidu has asked for the wisdom of the Perl Monks concerning the following question:

I need a perl script which remsh to another machine with different login and execute some command. I tried executing a simple perl code, but it does not execute the required command in the remote machine. Here in the remote machine /tmp/1 is empty, it does not output the ls command in /tmp/1

#!/app/perl `/usr/bin/remsh << EOF perlguru go4fun ls > /tmp/1 EOF`

    Have you tried your remsh script as a stand-alone shell script? Does it work as a stand-alone shell script?

    Launching complicated text as commands from Perl does not magically make things work.

      Even as shell script, I am getting same output as perl. i.e on remote machine commands are not getting executing. Any suggestions to improve the code ?


        If it's doing the same as a shell script, then it's not a perl problem. Solve the problem, and *then* bundle it into a perl script. There are many unix support forums that can help you with that bit.

        Having said that, I'd suggest doing something simple in your remsh script to help you find the problem, such as:

        set >RajNaidu.test.remsh

        Then log into the remote machine and locate the RajNaidu.test.remsh file and check that the directory and environment is what you expect. Then add bits of your script to it and echo your errors to a file to get clues as to what's failing and why.


        When your only tool is a hammer, all problems look like your thumb.
