Code:

awk '/use/ { ++u}/take/{ ++u }
END {
 if ( u == 0 && t == 0 ) {
   print "file: "FILENAME " has no use or take"
 }
}' file*

Probably intended:

Code:

awk '/use/ { ++u}/take/{ ++t }

cheers, drl

The awk I use, GNU Awk 3.1.4, does not reset variable when the filename changes, hence the variables remain as set with the most recent increase ... cheers, drl

If you take out the useless(tm) stuff, it's a fairly good solution.

Code:

for x in *.txt; do
  tr "\n" " " <"$x" | egrep -v 'use.*take|take.*use' >/dev/null && echo "$x"
done

I believe I've seen egreps which couldn't handle really long lines, so this might not be entirely robust, but the idea is workable.
