In bash, assigning arrays is not difficult, nor is the output:

$ IFS="," files=( $FNAME )
$ echo ${files[1]}
def.txt
$ for f in ${files[*]}; do echo $f; done
abc.txt
def.txt
ghi.txt

       -h --hosts

       -p --par

EXAMPLE

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

		    /home/irb2/foo.txt foo.txt

ENVIRONMENT

       o   PSSH_HOSTS
       o   PSSH_USER
