Yes, you can invoke sed inside awk, and yes, you can invoke awk inside awk; but there is very seldom any reason to do so.

You have already been shown several ways to do what you requested in your original post. So, I assume you must want to do something more than you have shown us.

Please explain what you're trying to do. Show us some sample input and what output you're trying to produce (using CODE tags). Show us the code you have tried and explain what it isn't doing that you want it to do.

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
