I'd suggest you:
  1. man grep
  2. apply the earned knowledge from 1. to the "test harness"

hi!
but bob,
ls -1t /some/dir | grep "^a"

doesnt seem to work......cause ls -l list al the parameters like
-x--x--x-- XXXX XXXX abc.sh

it displays other parameters appart from filename......but "^" wud start searching teh first character....so that doesnt seem to work rite?

Thnaks and Regards
