Two options, depending on your data.
First:
<your command> | while read TheLine
do
stuff with $TheLine
done
"read" can run into problems with some other commands, notably rsh so if you
plan to put rsh commands in the loop use the second mechanism. (Actually,
rsh is the only one which has ever given me trouble, but I'm sure there are
more out there.)
Second:
for TheLine in `<your command>` N.B. Back quotes, not normal quotes.
do
stuff with $TheLine
done
The only problem you might face here is is you have valid word separators in
your data. "for" will take each individual word, not necessarily each line
of data.

Subject: Korn Shell Q
Hello,
Quick, simple korn shell question:
I have the result of grep and cut commands that shows multiple lines. For
example:
345trh
hur88
kjsdhf
eryyt9
333ret
How can I divide these lines to feed into variables? That is, each of the
above lines needs to be assigned to a variable.
