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.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Replace DOS character ^M with newline using perl inline replace.
Shorter version with curl and awk
This will visit recursively all linked urls starting from the specified URL. It won't save anything locally and it will produce a detailed log.
Useful to find broken links in your site. It ignores robots.txt, so just use it on a site you own!
There's nothing particularly novel about this combination of find, grep, and wc, I'm just putting it here in case I want it again.
Shows useful informations about file descriptors in Squid web proxy
Used by virtualbox and others to create '.run' file.
this command will add the following two lines into the ~/.bash_aliases:
alias exit='pwd > ~/.lastdir;exit'
[ -n "$(cat .lastdir 2>/dev/null)" ] && cd "$(cat .lastdir)"
or redirect it to the ~/.bashrc if you like
Donno, I find it usefull. You may also define an alias for 'cd ~' like - alias cdh='cd ~'
sometimes you got conflicts using SSH (host changing ip, ip now belongs to a different machine) and you need to edit the file and remove the offending line from known_hosts. this does it much easier.
That's the key part.
I got this from http://www.macosxhints.com/article.php?story=20070715091413640. See that article for other other, more basic, tcsh-specific history-related settings.
Replace sed regular expressions with perl patterns on the command line.
The sed equivalent is: echo "sed -e"|sed -e 's/sed -e/perl -pe/'
This command deletes the "newline" chars, so its output maybe unusable :)
with grep for em:name rather than name, you will get much better result.
less ressources (processes) needed
Given a dump.sql file, extract table1 creation and data commands. table2 is the one following table1 in the dump file. You can also use the same idea to extract several consecutive tables.
Problem: you want to output one line per file. you can't just 'tr -d' because you want one line per file and you don't want to use a loop.
Solution: use awk to print each line without the record separator and a newline after each file.
Use meaningful exit codes
change "source" to "cat" to view output instead of assigning
