Check These Out

Get a brief overview of how many files and directories are installed
To start, you first need to make sure updatedb has been run/updatedb, and initialized the db: $ su -l root -c updatedb This locate command is provided through the mlocate package, installed by default on most GNU/Linux distributions. It's available on the BSDs as well. Not sure about support for proprietary UNIX systems. The output is self-explanatory- it provides an overview of how many directories and files are on your system.

Print a cron formatted time for 2 minutes in the future (for crontab testing)
Another function to stick into your .bashrc This spits out the time two minutes in the future, but already formatted for pasting into your crontab file for testing without any thought required on your part. Frequently things don't work the way you expect inside a crontab job, and you probably want to find out now that your $PATH is completely different inside of cron or other global variables aren't defined. So this will generate a date you can use for testing now, and then later you can change it to run at 5:37 am on a Sunday evening.

List PCI device with class and vendor/device IDs
This is a quick replacement for lspci if you need to know what's in a given system but pciutils is not installed. You then need something that can look up the IDs from pci.ids if you want the verbose output.

YES = NO

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.

Save a file you edited in vim without the needed permissions
Calls sudo tee like all the other lines, but also automatically reloads the file. Optionally you can add command Wq :execute ':W' | :q and command WQ :Wq to make quitting easier

iso-8859-1 to utf-8 safe recursive rename
This command is a powerful "detoxifier" that eliminates special chars, spaces and all those little chars we don't like. It support several "sequences" so be sure to check your /usr/local/etc/detoxrc while at it... and maybe define your own

Produce a pseudo random password with given length in base 64

move contents of the current directory to the parent directory, then remove current directory.
Robust means of moving all files up by a directory. Will handle dot files, filenames containing spaces, and filenames with almost any printable characters. Will not handle filenames containing a single-quote (but if you are moving those, it's time to go yell at whoever created them in the first place).

Create a bunch of dummy text files
Using the 'time' command, running this with 'tr' took 28 seconds (and change) each time but using base64 only took 8 seconds (and change). If the file doesn't have to be viewable, pulling straight from urandom with head only took 6 seconds (and change)
