commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

This is a bit shorter, only using awk:
numpages() { awk 'END{print int(NR/60)}' "$@"; }awk reads through the file, then has an END condition to print NR (number of records (lines)).
It's tempting to add a "+1" to the end, though. If the files are less than 60 lines in total, both our commands print: 0 !
