what is this grep doing

[tuka]

I found this script and I am trying to adapt it for my use
but I don't know what this grep statement is doing.


set db_tape=`/opt/openv/volmgr/bin/vmquery -bx -rn 0 | sort | grep Offs | grep '\-\-\-'|head -1 | awk '{print $1}'`

Can someone help me out on the grep.

Thanks !!!

the 1 grep looks for lines containing 'Offs'
the second for '---' the backslashes are needed to mask '-'
