using grep and cut:
cat com_get* | grep ^Logically | cut -d ' ' -f 5 | sort
sed is a lot of fun too:
cat com_get* | sed '/^Logically/!d; s/.* \(.*\)/\1/'
i always think of awk as a bigger program (true or not) so i try
to avoid it. in anycase, perl is almost always a better choice for
anything awk can do (IMO).
if there's only one file name to input avoid running cat (or more):
< com_get | program
or more traditionally:
program < com_get
having said that, this is linux, try them all.
