running a script file using pssh

[Raghava Mutharaju]

Hello all,

Is it possible to run a script file instead of putting everything on
the command line in pssh?

Eg: pssh -h hosts.txt -o ~/prj/output ~/prj/test.sh

Instead of putting all the contents of test.sh on the command line
itself.

Regards,
Raghava.

The -I/--send-input option may be what you're looking for. From the man
page:

"""Read input and send to each ssh process. Since ssh allows a
command script to be sent on standard input, the -I option may be used
in lieu of the command argument."""

Your example would become:

pssh -h hosts.txt -o ~/prj/output -I < ~/prj/test.sh

Let us know if it works for you.

Hello Andrew,

Thank you for the reply. I tried the following

./pssh -h ../hosts.txt -P -l<../test.sh

But I get the following error: 

Usage: pssh [OPTIONS] command [...]

pssh: error: -l option requires an argument

What could be the issue here?

Regards,

Raghava.

Your font might be the issue. :) That should be a capital letter i, not
a lower-case L. It's an easy mistake with a bad font. :)

Yes, that was the problem :), thank you. Now, it works fine.

Raghava.

Hi,

I am getting beow error when i do the above command as said by you :

 ./pssh -h input.txt -P -I< ./restartcollector_final.sh

Error: option -I not recognized

Usage: pssh [OPTIONS] -h hosts.txt prog [arg0] ..

  -h --hosts   hosts file (each line "host[:port] [user]")

  -l --user    username (OPTIONAL)

  -p --par     max number of parallel threads (OPTIONAL)

  -o --outdir  output directory for stdout files (OPTIONAL)

  -e --errdir  output directory for stderr files (OPTIONAL)

  -t --timeout timeout (secs) (-1 = no timeout) per host (OPTIONAL)

  -O --options SSH options (OPTIONAL)

  -v --verbose turn on warning and diagnostic messages (OPTIONAL)

  -P --print   print output as we get it (OPTIONAL)

  -i --inline  inline aggregated output for each server (OPTIONAL)

Example: pssh -h nodes.txt -l irb2 -o /tmp/foo uptime

please suggest what needs to be done

[Kev Smith]

the -l is OPTIONAL - if you supply the param it is expecting an ARGUMENT IE a username to connect with

try

 ./pssh -h input.txt -P < ./restartcollector_final.sh

OR

./pssh -h input.txt -P -l YOUR_USER < ./restartcollector_final.sh
