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

There are times when a X Window server hangs. When this happens, you can log in on a terminal and kill the Xorg process (i.e. the X Server). This one line command will do the trick.

Deletes files in the current directory or its subdirectories that match "regexp" but handle directories, newlines, spaces, and other funky characters better than the original #13315. Also uses grep's "-q" to be quiet and quit at the first match, making this much faster. No need for awk either.

Grep can search files and directories recursively. Using the -Z option and xargs -0 you can get all results on one line with escaped spaces, suitable for other commands like rm.

After this command you can review doit.sh file before executing it.

If it looks good, execute: `. doit.sh`

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

function gh () { history | grep $* ; } # gh or "grep history"

User: mpb
Functions: grep

By defining a function "gh" as shown here, it saves me typing "history | grep" every time I need to search my shell history because now I only have to type "gh".

A nifty time saver :-)

You can also add the "gh" function definition to your .bashrc so it is defined each time you login.

(updated 2015_01_29: changed from hg to gh to avoid clash with that other hg command.

mnemonic: gh = grep history)
