Hi, I have a file with a HDR, some lines (number of lines can vary) and a TRL. And this set is repeating. I have to insert 2 lines just after the TRL, but not after the last TRL. I was able to do it using SED, But as the business system does not support the SED, I have to rewrite the script. and the system supports awk. Please help. The file is like, HDR --- --- --- TRL HDR --- --- TRL and expected is HDR --- --- --- TRL 1st line 2nd line HDR ---- ---- TRL

This uses just the korn shell: #!/bin/ksh cnt=$(wc -l < datafile) echo $cnt ncnt=0 while read line do ((ncnt+=1)) echo "$line" if [[ "$line" = "TRL" && $ncnt -ne $cnt ]] then echo "line 1" echo "line 2" fi done < datafile > newdatafile

Hi nails, thanks a lot for the solution. I have one more problem here which i did not mention. There will be more text after TRL, like "TRL 00 123 1235" i have to check it the line starts with "TRL and then do the rest. I tried using ^TRL, /^TRL/, it did not work. Please help me. Thanks a lot Pradeepa

How about trying the case statement: #!/bin/ksh cnt=$(wc -l < data2) echo $cnt ncnt=0 while read line do ((ncnt+=1)) echo "$line" case "$line" in TRL*) if [[ $ncnt -ne $cnt ]] then echo "line 1" echo "line 2" fi ;; esac done < datafile

hey nails, thanks a lot, It works.

Hey, when I do an echo the trailing tab spaces are removed, for example when i have the text "This is Testing tab <tabspace> " Could not press a tab.... When I do an echo of this, the tabspace is removed. Please help me as i want this tabspace after this. Thank you
