Stay in the loop…

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.

you don't need to echo, just a plain redirect is enough to empty the file

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives

Empties all files in /var/log over 5000k. Useful if /var goes crazy or if you just haven't cleaned up in a while.

Know a better way?

If you can do better, submit your command here.

What others think

The bash for loop works, but you can do it with less typing with a single find command using find's -exec option:

find /var/log -type f -size +5000k -exec cp /dev/null {} \;

this will invoke cp once for each file, copying /dev/null to it. They syntax of -exec just replaces {} with the name of each file found and runs cp. If you were just deleting those files, you could use the -delete option in place of -exec. See the "ACTIONS" section of the find manpage for more.

Why would you need to use this command when logrotate + cron does it for you already?
