simple awk question

Hi gang. I have an awk one-liner:

grep $STRING $FILE | awk '{printf "%-6s %s\n", $11,$13}' | sort

Its output is:


How can I add a column so I get this:

1 6001
2 6002
3 6003

Thanks for your interest in this important matter.

Presuming I understand what you're asking, you can use awk's special variable - NR. It contains the number of input records awk has processed, and if you print it you can use it as a "record count".

Might mess up your sort though. It all depends on your data and what you're trying to do exactly...

Or you could pipe the sort output to another awk script, vis:

. . . | sort | gawk '{print NR ": " $0};'
