combining unix commands and awk program
Dear Experts
I am trying to find if it is possible to combine unix commands in awk program. For example if it is possible embed rm or ls or any unix command inside the awk program and while it is reading the file besides printing be able to do some unix commands. I am thinking may be just print and printf or reformating there are other tasks that can be done by awk
Very Best regards
Reza
