I have this script and I would like to print a single title before executing the conditional if

>Solution :
Since there was no input example, I used your "Output I have" as input.
I also checked if the whole line contains the word terror or bird, but you can change it if you need the column where it is.
cat testInput | awk '{ if(toupper($0) ~ /TERROR/) { varTerror=varTerror"\n"$0; next; } if(toupper($0) ~ /BIRD/) {varBird=varBird"\n"$0; next; } } END { if(varTerror != "") { print " ***** Terrorism accidents ******* "; print varTerror } if(varBird != "") { print " ******** Bird accidents ******** "; print varBird } }'
