Shell Programming and Scripting

Hello all, I've got a script that collects data on file systems and prints out specific data about each. I've formatted headers w/ printf like so.

Code:

printf "\033[4mVolume Name\tDisk\t\tBlock Device\t\t\t\tMount Point\t\tSize\tOwnership\033[0m\n"

and I had the content of the varibles printed out beneath those columns like so:

Code:

printf "${volume}\t${diskvol}\t${blockdevice}\t\t${mntpnt}\t\t${fssize}\t${owner}\n"

The problem I've run into is that should one of those variables contain multiple entries if ruins the formatting. I've experimented with printf and to attempt to overcome it but I'm not successful thus far.

The code I have at the moment is below.

Code:

printf "%-5s%-10s%-15s%-10s%-5s" ${volume} ${diskvol} ${blockdevice} ${mntpnt} ${fssize} ${owner}

actual output of the script attached.

Essentially the headers are fine. Its the data that follows that has no spacing and isnt respecting the "spaces" i defined.

Help appreciated
