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, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
