Display a cool clock on your terminal
This command displays a clock on your terminal which updates the time every second. Press Ctrl-C to exit. A couple of variants: A little bit bigger text: $ watch -t -n1 "date +%T|figlet -f big" You can try other figlet fonts, too. Big sideways characters: $ watch -n 1 -t '/usr/games/banner -w 30 $(date +%M:%S)' This requires a particular version of banner and a 40-line terminal or you can adjust the width ("30" here).

List files with quotes around each filename

A sorted summary of disk usage including hidden files and folders
Same result as with 'du -ks .[^.]* * | sort -n' but with size outputs in human readable format (e.g., 1K 234M 2G)

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'

Compare two directories
Output of this command is the difference of recursive file lists in two directories (very quick!). To view differences in content of files too, use the command submitted by mariusbutuc (very slow!): $ diff -rq path_to_dir1 path_to_dir2

Add prefix onto filenames
Best to try first with -n flag, to preview
