Hi, I am comparing 2 files and if any error found i am sending message to tmpfile4 and mailing it to dba team. counter=1 exec 3< ${tmpfile} while read -u3 line do grep "$line" ${tmpfile3} 1>/dev/null if [[ $? -eq 1 ]] then print "Warning: File $line is missing from the archived log directory !!!" >> $tmpfile4 fi (( counter += 1 )) done Here, If nothing is missing, I would like to add only one line "nothing is missing" to tmpfile4. How do I do it? If I include it inside the 'IF condition above, It will print for each line of comparison. I just want to print one line after comparison nothing is found missing. Any help? Thanks and Regards Suresh sureshht

This worked for me: #!/bin/ksh tmpfile=suresh1.data tmpfile3=suresh2.data counter=0 exec 3< ${tmpfile} while read -u3 line do grep "$line" ${tmpfile3} 1>/dev/null if [[ $? -eq 1 ]] then print "Warning: File $line is missing from the archived log directory !!!" >> $tmpfile (( counter += 1 )) fi done if [[ $counter = 0 ]] then print "nothing is missing" fi

I can't believe I made such an rookie mistake in my solution. Severe brain cramp. #!/bin/ksh tmpfile=lemieux1.data tmpfile3=lemieux2.data counter=0 exec 3< ${tmpfile} while read -u3 line do grep "$line" ${tmpfile3} 1>/dev/null if [[ $? -eq 1 ]] then print "Warning: File $line is missing from the archived log directory !!!" >> $tmpfile4 (( counter += 1 )) fi done if [[ $counter -eq 0 ]] then print "nothing is missing" fi

Hey, Thanks for your response. Not working for me. Thanks Suresh sureshht

If it is not working, then you have a different issue. If you create data file A and copy it to data file B, you can then run the script I gave you and compare the 2 files. It will print "nothing is missing" since the 2 files are identical. Perhap if you change: print "nothing is missing" to print "nothing is missing" >>$tmpfile4 You'll get the desired result.
