Stay in the loop…

Follow the Tweets.

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.

Run the built in PHP-server in current folder

You must have PHP 5.4.0 or later to be able to run the built in server.

This web server is designed for developmental purposes only, and should not be used in production.

URI requests are served from the current working directory where PHP was started, unless the -t option is used to specify an explicit document root. If a URI request does not specify a file, then either index.php or index.html in the given directory are returned. If neither file exists, then a 404 response code is returned.

If a PHP file is given on the command line when the web server is started it is treated as a "router" script. The script is run at the start of each HTTP request. If this script returns FALSE, then the requested resource is returned as-is. Otherwise the script's output is returned to the browser.

Standard MIME types are returned for files with extensions: .css, .gif, .htm, .html, .jpe, .jpeg, .jpg, .js, .png, .svg, and .txt. The .htm and .svg extensions are recognized from PHP 5.4.4 onwards.

More information here: http://php.net/manual/en/features.commandline.webserver.php

Get a list of Mageia Linux mirrors providing rsync connectivity for Mageia 3 release

Need to find a Mageia Linux mirror server providing Mageia 3 via rsync?

Modify the "url=" string for the version you want. This shows i586 which is the 32bit version.

If you want the 64bit version it is:

url=http://mirrors.mageia.org/api/mageia.3.x86_64.list; wget -q ${url} -O - | grep rsync:

Recursively search and replace old with new string, inside every instance of filename.ext

This is a slightly modified version of http://www.commandlinefu.com/commands/view/4283/recursive-search-and-replace-old-with-new-string-inside-files (which did not work due to incorrect syntax) with the added option to sed inside only files named filename.ext
