You need: pxz for the actual work (http://jnovy.fedorapeople.org/pxz/). The function could be better with better multifile and stdin/out support.

Know a better way?

If you can do better, submit your command here.

What others think

Hmm... pv is a wonderful tool, but I'm not sure about the rest.

First of all, pxz works out, for itself, how many processors/threads it can use.

Even if you did need to tell it, you don't need "wc -l"; grep has a count option.

THREADS=$(grep -c processor /proc/cpuinfo)

Finally, quote your arguments to allow whitespace in filenames. "$@" does the right thing.

for file in "$@"; do pxz "$file"; done
