Pradeep,
    The shell function abc
is defined in your bash script which will not be defined on the machines
in which you are trying to run it.
Convert it into a bash script and invoke
that.

Hi all,
  I am trying to write a program which will connect to all the client
machines once by ssh and run a particular tool using different user
credentials in that single connection.

I thought of writing the program as below. But I am getting an error "abc
not found" and the test fails. I guess there is a Bug for this already.

Is there any other way I can perform this task. Any example will really
help to achieve this kind of task.

Regards
Pradeep.

I tried to subscribe to mailing list but it doesnot work for some reason
i
guess. I did not get the confirmation email after two days.

Hi Pradeep.

GNU Parallel is capable of what you want to do.

It is unclear whether you have:

* watched the intro videos
https://www.youtube.com/playlist?list=PL284C9FF2488BC6D1
* walked through the tutorial
(http://www.gnu.org/software/parallel/parallel_tutorial.html
or man
parallel_tutorial)
* read the man page (man parallel - Read at least the examples)

In the man page it says:

       Your bug report should always include:

       ? The error message you get (if any).

       ? The output of parallel --version. If you are not
running the latest
         released version you should specify why you
believe the problem is
         not fixed in that version.

       ? A complete example that others can run that shows
the problem. This
         should preferably be small and simple. A combination
of yes, seq,
         cat, echo, and sleep can reproduce most errors.
If your example
         requires large files, see if you can make
them by something like
         seq 1000000 > file or yes | head -n 10000000
> file.

       ? The output of your example. If your problem is
not easily
         reproduced by others, the output might help
them figure out the
         problem.

Based on your example alone it does not look like a bug, so try to
provide the missing information.
