That's kind of brilliant, the single quotes in the middle cancel out the outer quotes..   isi_for_array 'echo $(hostname)'  would translate to   isi_for_array 'tar -cvjf /ifs/css-backups/c702/$(hostname)_usr-backup.tar.bz2 /usr/'
Community,  I am trying to backup the following directories:  /usr/ /var/ /etc/mcp/override  per the pre upgrade steps.  I need help with the syntax I would use to tar those directories using isi_for_array?  i.e..  tar -cvjf /ifs/backup/$HOSTNAME-usr-backup.tar.bz2 /usr/  (I need the HOSTNAME for every node to be represented in the naming of the file.)  My attempts to make this work netted me this output (-usr-backup.tar.bz2)  Remember this will have to work using isi_for_array.   Thank you,
Command Syntax using isi_for_array (tar, and $HOSTNAME)
