this takes a few minutes on old debian machine, taking much longer here on same data- about 19k file about 24Gb total size. Windoze finally has better perf stuff but still no help- one core at 25 pct all kernel time disk not exactly busy. All the time is in the "ls" loop not the find command. Now obbviously I expect the "ls" per file has to make a bunch of OS calls for each file but still even with cygwin layer seems a bit much. Thanks. $ more tots foo="" #ls -al `find -type f| awk '{print \$0}' ` | awk '{tot=tot+\$5; }END{print tot} ' #ls -al `find -type f ` | awk '{tot=tot+$5; }END{print tot}' find -type f > xxx cat xxx | while read do ls -al "$REPLY" done | awk '{tot=tot+$5; }END{print tot}' -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
