Check if it's your binary birthday!
Print out your age in days in binary. Today's my binary birthday, I'm 2^14 days old :-) . This command does bash arithmatic $(( )) on two dates: Today: $(date +%s) Date of birth: $(date +%s -d YYYY-MM-DD) The dates are expressed as the number of seconds since the Unix epoch (Jan 1970), so we devide the difference by 86400 (seconds per day). . Finally we pipe "obase=2; DAYS-OLD" into bc to convert to binary. (obase == output base)

Open a file in a GTK+ dialog window
I use zenity because it's a rewrite of gdialog and also replaces gmessage and has more useful options. Using --text-info allows you to select and copy the text to your clipboard. To see a file in a list dialog: cat /etc/passwd | zenity --width 800 --height 600 --list --column Entries If you don't have zenity, you'll have to download it via apt-get install zenity, etc.
