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.

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,…):

Converts control codes and spaces (ASCII code ≤ 32) to visible Unicode Control Pictures, U+2400 ? U+2420. Skips \n characters, which is probably a good thing.

Does a search and replace across multiple files with a subgroup replacement.
Lists directory size up to a maximum traversal depth on systems like IBM AIX, where the du command doesn't have Linux's --max-depth option. AIX's du uses -g to display directory size on gigabytes, -m to use megabytes, and -k to use kilobytes. tr### is a Perl function that replaces characters and returns the amount of changed characters, so in this case it will return how many slashes there were in the full path name.
When trying to find an error in a hosted project it's interesting to find out how the source is organized: Are there .inc files? Or .php files only? Or .xml files that probably contain translated texts?

How much memory is chrome sucking?
`pwd` returns the current path
`grep -o` prints each slash on new line
perl generates the paths sequence: './.', './../.', ...
`readlink` canonicalizes paths (it makes the things more transparent)
`xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR.
The original command doesn't work for me - does something weird with sed (-r) and xargs (-i) with underscores all over...
This one works in OSX Lion. I haven't tested it anywhere else, but if you have bash, gpg and perl, it should work.
When you need a quick ref guide while troubleshooting Apache|NGINX error|access logs.
1.- Enter into the playlist path.
2.- Run the command.
