UNIX find writable files

Way back when, I posted about using find and grep.  I have learned a couple of things since then.

1) find your critiera | xargs grep your grep criteria … is nicer to your processor, memory, and quickly returning the results.

2) finding writable files.  This has been particularly useful when using a really backwards SCS that doesn’t integrate nicely, cleanly, or usable with an IDE.

My command:  find . -type f -perm /u=w

So simple. So elegant. So simply says “find all files in this directory, recursively, that are writable by the user/owner”. The one confusing thing I had about this was /u instead of /o. I figured “owner, group, world”, but it is actually “user, group, other(s)”.

Anyway, this has improved my programming life.  Yeah, I’m gonna say it… take that, Windows.
