Re: help on remote ssh cmd

[p sena]

Thanks Ole.

Somehow the --tag & --nonall or --onall did not worked for me. Hence i made use this way-

parallel -j 1 --basefile some-file-2-copy  -S H1,H2 ::: "hostname && /home/username/that-file-copied" "hostname && /home/username/that-file-copied"

Is this Ok ?

If I use --tag with --nonall or --onall then I get this err msg & it hang up-

parallel: Input is tty. Press CTRL-D to exit.

 thanks.

Hi Sena.

Please use parallel@gnu.org for support.

For running the same command on remote computers please read:

http://www.gnu.org/software/parallel/man.html#example__running_the_same_command_on_remote_computers

You may also learn something by reading the rest of the examples.
