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,…):

Very quick! Based only on the content sizes and the character counts of filenames. If both numbers are equal then two (or more) directories seem to be most likely identical.
if in doubt apply:
diff -rq path_to_dir1 path_to_dir2
AWK function taken from here:
OpenOffice, LibreOffice and OO Impress wordcount
This lists the number of ogg/mp3/wav/flac files in each subdirectory of the current directory. The output can be sorted by piping it into "sort -n".
-L is for following symbolic links, it can be omitted and then you can find in your whole / dir
RU: Найдет число файлов в папке по данной маске в цикле по дням месяца
This has saved me many times while debugging timeout issues to "too many open files" issues. A high number of the order of thousand, indicates that somewhere connection is not being closed properly.
Count your source and header file's line numbers. This ignores blank lines, C++ style comments, single line C style comments.
This will not ignore blank lines with tabs or multiline C style comments.
Bases word count on the genreated PDF file; so make sure to update this first. The PDF file also includes references and output of any macros.
I have found that base64 encoded webshells and the like contain lots of data but hardly any newlines due to the formatting of their payloads. Checking the "width" will not catch everything, but then again, this is a fuzzy problem that relies on broad generalizations and heuristics that are never going to be perfect.
What I have done is set an arbitrary threshold (200 for example) and compare the values that are produced by this script, only displaying those above the threshold. One webshell I tested this on scored 5000+ so I know it works for at least one piece of malware.
calculate how many different lines between two files
(Please see sample output for usage)
Use any script name (the read command gets it) and it will be encrypted with the extension .crypt, i.e.:
myscript --> myscript.crypt
You can execute myscript.crypt only if you know the password. If you die, your script dies with you.
If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string).
Not difficult to make script editable (an offset-dd piped to a gpg -d piped to a vim - piped to a gpg -c directed to script.new ), but not enough space to do it on a one liner.
Sorry for the chmod on parentheses, I dont like "-" at the end.
Thanks flatcap for the subshell abbreviation to /dev/null
Output of a command as input to many
Kind of fun if you're that was inclined. I figured most of my commands start with s. sudo, screen, ssh etc. This script tells me what else they start with.
ls -1 shows one file per line (update: -1 was not really needed)
wc -l counts the lines received from the previous command
