Binary clock
Fun idea! This one adds seconds and keeps running on the same line. Perl's probably cheating though. :)

Compare two directory trees.

Print a list of all hardlinks in the working directory, recursively
libpurple likes to hardlink files repeatedly. To ignore libpurple, use sed: | sed '/\.\/\.purple/d'

generate a random 10 character password
Generate a table of random 10 character passwords

Remind yourself every 15 minutes (repeated reminders)
Note: 1) -n option of watch accepts seconds 2) -t option of notify-send accepts milliseconds 3) All quotes stated in the given example are required if notification message is more than a word. 4) I couldn't get this to run in background (use of & at the end fails). Any suggestions/improvements welcome.

Remotely sniff traffic and pass to snort
I have a small embedded linux device that I wanted to use for sniffing my external network, but I didn't want to recompile/cross-compile snort for the embedded platform. So I used tcpdump over ssh to pass all the traffic as pcap data to a "normal" Linux system that then takes the pcap data and passes it to snort for processing.

ping a range of IP addresses
nmap accepts a wide variety of addressing notation, multiple targets/ranges, etc.

convert filenames in current directory to lowercase
This will convert filenames from uppercase to lowercase. I find this useful after downloading images from my digital camera. This works for English, but other languages may need something slightly more complex like this: $ for i in *; do mv "$i" "$(echo $i|tr [:upper:] [:lower:])"; done Also, the quote marks aren't necessary if your filenames don't contain spaces.

32 bits or 64 bits?
Easy and direct way to find this out.
