Update: As Pádraig Brady, fslint maintainer, pointed out: fslint/findup *is* a shell script.
My 500-GB Seagate FreeAgent Desktop is almost filled to the brim (there’s *only* ~70GB free space left) so I need to find all duplicate files for clean-up.

We already know how to update Twitter from the command line. To get your and your friends’ timeline from the CLI, use the following one-liner:

Using the same method, you can also get unread Gmail inbox messages (via commandlinefu.com).

I found a nifty way of updating my Twitter status through the command line:

curl -u username:password -d status=’status_goes_here’ -s http://twitter.com/statuses/update.xml > [...]

$ for i in `seq 100` ; do if [ `expr $i % 15` -eq 0 ] ; then echo FizzBuzz; elif [ `expr $i % 3` -eq 0 ]; then echo Fizz; elif [ `expr $i % 5` -eq 0 ]; then echo Buzz; else echo $i; fi; [...]
