Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Looking for files called .svn? ;-)
find . -name "*\.svn" -exec rm -rf {} ";" might be better.
Much better would be:
find . -name "*\.svn" -exec echo {} +
Why? Performance!
for n in `seq 1 1 1000`; do touch $n.svn; donetime find . -name "*\.svn" -exec echo {} \; 1>/dev/nullreal 0m2.629s
user 0m0.970s
sys 0m1.655s
time find . -name "*\.svn" -exec echo {} + 1>/dev/nullreal 0m0.020s
user 0m0.012s
sys 0m0.007s
What's with
find . -name ".svn" -type d | xargs rm -rf-> -type d tells find to only find dirs
-> xargs starts onyl one rm subprocess and not one rm subprocess for each found dir like find's exec option does. So it is much more efficient.
Also... If you're using find to remove directories, use the -depth option (search deep first).
find . -depth -type d -name .svn -exec rm {} \;This will prevent errors from find trying to descend into directories that it's just deleted.
@OJM: the directories are called ".svn", it's not a file extension but a hidden directory.
Agreed on the + vs "\;" suggestion
