[ale] bash assistance

Excuse the top post:  Windows client here:  No choice in that matter:

Looks interesting and I want to clear my plate to dive into this and understand it.

Thanks all.

yeah. The long name causes a line wrap. But the latest coreutils here doesn't change that.
Need to change the process to be

for mntp in /dev/mapper/vg1_foo /dev/mapper/vg2_foobar;
do
echo "$mntp $(df -T $mntp | grep "^ " | awk '{print $5}')"
done

This is because you have a long volume name. Upgrading to latest coreutils may help.
