Site originally by David Winterbottom (user root).

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

find the biggest files recursively, no matter how many

A different approach to the problem - maintain a small sorted list, print the largest as we go, then the top 10 at the end. I often find that the find and sort take a long time, and the large file might appear near the start of the find. By printing as we go, I get better feedback. The sort used in this will be much slower on perls older than 5.8.

Look for timthumb.php or thumb.php and get its version.

Good for finding outdated timthumb.php scripts which need to be updated, anything over 2.0 should be secure, below that timthimb is vulnerable and can be used to compromise your website.

Create a false directory structure for testing your commands

You could avoid xargs and sed in this case (shorter command and less forking): At least bash and zsh have some mighty string modifiers.

I would also suggest using find with exec option to get more flexibility. You may leave out or include "special" file for example.

Makes you look busy

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

Converts all jpg files to 75 quality.

Requires ImageMagick to be installed.

This command was stolen from @climagic on Twitter.

Probably a duplicate of command below, but this command uses slightly higher quality.

find builtin in bash v4+

This command will give you the same list of files as "find /etc/ -name '*killall' | xargs ls -l".

In a simpler format just do 'ls /etc/**/file'.

It uses shell globbing, so it will also work with other commands, like "cp /etc/**/sshd sshd_backup".

Find all e-mails older than 7 days in the queue and delete them

Find all files in /var/spool/mqueue older than 7 days, pass to perl to efficiently delete them (faster than xargs or -exec when you've got millions or hundreds of thousands to delete). Naturally the type, directory, and file age vars can be adjusted to meet your specific needs.
