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. Fortunately, there are tools to do just this. I tried fslint, which is also available [...]

I found a nifty way of updating my Twitter status through the command line: curl -u username:password -d status=’status_goes_here’ -s [...]

Hmmm… In Bash, I would have done: $ 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; [...]
