That's really interesting, I've had no idea: % find /usr/ -name "*.pyc" | wc -l # All .pyc files 18376 % find /usr/ -name "*.pyc" -links +1 | wc -l # .pyc files that are hard linked 15761 find /usr/ -name '*.pyc' -links 1 -print0 | du --files0-from=- -ch | tail -n1 # Total size of non-hardlinked .pyc files 65M total If I'm correct here it looks like it wouldn't really be worth it. > -- > devel mailing list > devel@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/devel > Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
