AWK Quick Columns

UNIX Programming, Certification, System Administration, Performance Tuning Reference Books AWK Quick Columns

Most of the time when you use awk from the command line, you're doing something simple like this:

ps -ef | grep netscape | awk '{print $2}'

To save typing, use this script when you only want to use awk to print out one or more columns:

#!/bin/ksh
# awkc - print out one or more columns

p=\$$( echo $1 | sed 's/,/,\$/g' )
shift
eval "awk '{ print $p }'" $*

# eof

--------------------------------------------------------------------------------

Now you can do things like:

ps -ef | awkc 2,1
or
awkc 1,2,3 /var/adm/messages*
