Stupid question number 1: What shell are you using interactively?


Stupid question number 2: How are you invoking your shell-script?


You are probably using bash interactively; most Linux users are. You may be using sh or /bin/sh to run your script. They are different shells, and have different features. Make sure your script is invoked thus:
Code:
bash script

and the first line looks like:
Code:
#!/bin/bash

Now, finally, you are using extended globbing in your copy. Extended globbing is an option in bash, and it has to be turned on. Add this line to the top of your script:
Code:
shopt -s extglob

and let us know if you are still having problems.

DESCRIPTION

       pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
       homogenously-configured hosts.

OPTIONS

       -r --recursive
	   recusively copy directories (OPTIONAL)

       -L --localdir
	   output directory for remote file copies

       -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)

EXAMPLE

       An example to copy /home/irb2/foo.txt from each host. Files gathered will be stored in /tmp/outdir/hostname/foo.txt.

	   # prallel-slurp -h hosts.txt -L /tmp/outdir -l irb2 
		    /home/irb2/foo.txt foo.txt

ENVIRONMENT

       All four programs take similar sets of options. All of these options can be set using the following environment variables:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
       o   PSSH_OUTDIR
