You mean this line?
LOG=`ls -al $DIR | grep $t | grep WINDOWS`
You're listing the contents of the directory, trying to find the one line
that contains the name of the file ($t) you're currently considering. Then
you're using grep a second time to only select (from that one line) any lines
that contain the text 'WINDOWS'. Presumably none of the files in
1group_1a_dev_clientlist.out have the word "WINDOWS" in their name.
What are you *trying* to do with that second grep?
cheers,
