Unix Tip #4145- June 17, 2012
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 $2}'
To save typing, use this script when you only want to
use awk to print out one or more columns:
------------------- CUT HERE ---------------------------
#!/bin/ksh
# awkc - print out one or more columns
p=\$$( echo $1 | sed 's/,/,\$/g' )
shift
eval "awk '{ print $p }'" $*
# eof
------------------- CUT HERE ---------------------------
Now you can do things like:
ps -ef | awkc 2,1
or
awkc 1,2,3 /var/adm/messages*
