Hi, I have to compare 2 files using shell script. I need to take the each entry/line from the first file and compare it with 2nd file whether that entry exists in second file or not. If found...ok..else I have to send warning msg. Please help me. Thanks and regards Suresh sureshht

I'm assuming that their is a possibility that the entries are not in the same order in both files, correct? If they are in the same order, I'd suggest you check the man pages for the diff command. Otherwise, you can loop through one file, reading each line and use grep to see if it is in the other file. Given a file (called junk1) with the following data: 1234 5678 9012 3456 Hi mom Given a file (called junk2) with the following data: 9012 1234 3456 5678 This script will give you the line in junk2 that is not in junk1: #!/bin/ksh counter=1 exec 3< junk1 while read -u3 line do grep "$line" junk2 1>/dev/null if [[ $? -eq 1 ]] then print "Line $counter ain't in the junk2 file!!!" fi (( counter += 1 )) done When you run the script, your output will look like this: Line 5 ain't in the junk2 file!!!

Hi, Script is exactly what i wanted. Thanks a lot for your help Suresh sureshht
