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/
You can sign-in using OpenID credentials, or register a traditional username and password.
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,…):

Returns the version of the kernel module specified as "MODULENAME", when available.
`pwd` returns the current path
`grep -o` prints each slash on new line
perl generates the paths sequence: './.', './../.', ...

In these command i use lynx to get the top trend topic of Mexico, if you replace Mexico with other country, you will get the #1 Trending topic
Replace "user/sbin/sshd" with the file you would like to check. If you are doing this due to intrusion, you obviously would want to check size, last modification date and md5 of the md5sum application itself. Also, note that "/var/lib/dpkg/info/*.md5sums" files might have been tampered with themselves. Neither to say, this is a useful command.
Created to deal with an overzealous batch rename on our server that renamed all files to .jpg files.
Long listing alternative
Get the amount of physical memory in an HP-UX v11 OS when following are NOT available:

instead of printing the whole line, print just the capture matched, but with the "cut" pipe :( I'm so sad with grep.
When you need a quick ref guide while troubleshooting Apache|NGINX error|access logs.
Shows a sigclass 0x20 (Key revocation) signature packet on a key, including all subpackets. Subpacket 2 is the date of revocation, subpacket 26 the relevant policy, subpacket 29 the reason of revocation (cf. http://rfc.askapache.com/rfc4880/rfc4880.html#section-126.96.36.199 ) and subpacket 16 the issuer of the revocation certificate (usually should be the same as the revoked key).
On the Mac, the 'ls' function can sort based on month/day/time, but seems to lack ability to filter on the Year field (#9 among the long listed fields). The sorted list continuously increases the 'START' year for the most recently accessed set of files. The final month printed will be the highest month that appeared in that START year. The command does its magic on the current directory, and suitably discards all entries that are themselves directories. If you expect files dating prior to 2002, change the START year accordingly.
grep '^[^#]' sample.conf
\__/ |||| \_________/

| |||| \- Filename
| |||\- Only character in group is '#'
| ||\- Negate character group (will match any cahracter *not* in the
| || group)
| |\- Start new character group (will match any character in the

| \- Match beginning of line
\- Run grep
Empty lines will also be not matched, because there has to be at least one non-hash-sign character in the line.
Avoids cat abuse ;)
This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.
On wired connections set 'eth0' instead of 'wlan0'
Replace \-dev with whatever you wanna search for
