Follow the Tweets.

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.

Recursively delete .svn folders

This is fast and efficient because rm is only run once.


There are 4 alternatives - vote for the best!

What others think

this isn't even the right command

find . -name .svn |xargs -i rm -rf {}

"Normally xargs places input arguments at the end of command. Used with the -i option, xargs will replace all instances of {} with input arguments. You need to put them in single brackets or use a backslash (\) before each bracket to keep the shell from interpreting the special characters. "

They mean the same thing. No need for -i when you want the subject to appear at the end.

Nottings, that's rubbish. No need for -i

The most efficient and secure method of solving this problem is to use the ?-delete? action:

find /var/tmp/stuff -mtime +90 -delete

This alternative is more efficient than any of the ?-exec? or ?-execdir? actions, since it entirely avoids the overhead of forking a new process and using exec to run /bin/rm. It is also normally more efficient than xargs for the same reason. The file deletion is performed from the directory containing the entry to be deleted, so the ?-delete? action has the same security advantages as the ?-execdir? action has.
