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,…):

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.
Given a bunch of files with "wrong" date naming, it renames them in a "good" format.
If you have a logfile where some lines start with timestamps like "2014-05-01 12:34:56,123" but other lines are missing the timestamp (like stack traces or object dumps), then use this script to copy the most recent timestamp to any lines that are missing it.
This is useful for merging log files, since you can then safely sort by timestamp to merge the files.
Tired of front end developers using short open tags in your views? This will replace all instances of
Note that in the command N is, for instance, 37.
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.
Sets the @ A record for your domain hosted by namecheap to your current internet-facing IP address, logs success or failure with syslog, and logs the data returned to /root/dnsupdate.
Change the XXX's as appropriate.
xmas lights for your terminal - switching the $l value to something like 1200 and zooming out on your terminal gives a great view ...
Found it on:
The yet most simple way to read all the contents of a file to a variable. I used it in a perl script to replace $text="`cat /sys/...`", and stipping down 9 secs of runtime due less forks
`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.
Since none of the systems I work on have readlink, this works cross-platform (everywhere has perl, right?).
Note: This will resolve links.
This attempts to load a Perl Module (-M flag) and use version 9999, since no module has a version this high, Perl exits either a) telling you the version of the module installed or b) tells you it can't find the module.
Shows the path if the module is installed or exit quietly (to simply avoid the 'No documentation found' msg).
This version uses a bash function and does not print the path to the module.
Using perl and tput, show all the colors with numbers that your actual $TERM can handle.
If want to remove the numbers at beginning of new line, it should be something like this:
perl -E 'say `tput setb $_`," "x `tput cols`, `tput sgr0` for 0 .. (`tput colors` - 1)'
Just another FizzBuzz in Perl.
