This is becoming a greatest hit on commandlinefu. awk allows use of uninitialized variables, so you could write: ... xargs du -k | awk '{t+=$1} END {print t}' Further, the job that xargs is doing can be done by find here using the multiple-args-per-invocation -exec option: find $DIR -type f -name "*txt*" -exec du -k {} + | awk '{t+=$1} END {print t}' The '{}' is where the filenames are put, and the '+' indicates to run du on many arguments at once. See 'man find' for more.

Looks like the best way to do this is to us the -c option of du to produce a grand total, taking the place of the awk summation part.

Assuming your version of du has a -c option of course (Solaris 10 bundled version doesn't).
