Commands using cut

Run this command when you are physically at the computer you wish to send pop-up messages to. Then when you ssh in to it, you can do this: echo "guess who?" > commander

guess who? will then pop up on the screen for a few moments, then disappear. You will need to create the commander file first. I mess with my wife all the time with this. i.e. echo "You have given the computer a virus. Computer will be rendered useless in 10 seconds." > commander

lol

Uses google api to translate, you can modify the language in which translate modifying the parameter "langpair=|en", the format is language input|language output.

Not sure if it works the same on any shell.

if you need to install cron jobs in a given time range.

Same as original, but works in bash

Matrix Screen HPUX

you will hear how many seconds since 1.1.1970 in english words with billions, millions and thousands.

this is very useful, if you want to get over to use the unixtimestamp instead of the 24 hour clock in your dayly life

count the times a domain appears on a file which lines are URLs in the form http://domain/resource.

Gives you a list for all installed chrome (chromium) extensions with URL to the page of the extension.

With this you can easy add a new Bookmark folder called "extensions" add every URL to that folder, so it will be synced and you can access the names from every computer you are logged in.

Only tested with chromium, for chrome you maybe have to change the find $PATH.

It will change the reserve_lock attribute to all AIX EMC disk attached.

The ^python$ is a package name patten. You can change whatever you want.

Currently Facebook has updated their headers to display 127.0.0.1 but if you have saved e-mails from messages and FB related mail you can still reveal the IP. :)

Tested on Mac OS X 10.6.3

Just a quick hack to give reasonable filenames to TrueType and OpenType fonts.

I'd accumulated a big bunch of bizarrely and inconsistently named font files in my ~/.fonts directory. I wanted to copy some, but not all, of them over to my new machine, but I had no idea what many of them were. This script renames .ttf files based on the name embedded inside the font. It will also work for .otf files, but make sure you change the mv part so it gives them the proper extension.

REQUIREMENTS: Bash (for extended pattern globbing), showttf (Debian has it in the fontforge-extras package), GNU grep (for context), and rev (because it's hilarious).

BUGS: Well, like I said, this is a quick hack. It grew piece by piece on the command line. I only needed to do this once and spent hardly any time on it, so it's a bit goofy. For example, I find 'rev | cut -f1 | rev' pleasantly amusing --- it seems so clearly wrong, and yet it works to print the last argument. I think flexibility in expressiveness like this is part of the beauty of Unix shell scripting. One-off tasks can be be written quickly, built-up as a person is "thinking aloud" at the command line. That's why Unix is such a huge boost to productivity: it allows each person to think their own way instead of enforcing some "right way".

On a tangent: One of the things I wish commandlinefu would show is the command line HISTORY of the person as they developed the script. I think it's that conversation between programmer and computer, as the pipeline is built piece-by-piece, that is the more valuable lesson than any canned script.

The cut should match the relevant timestamp part of the logfile, the uniq will count the number of occurrences during this time interval.

Change the cut range for hits per 10 sec, minute and so on... Grep can be used to filter on url or source IP.

similar to the previous command, but with more friendly output (tested on linux)

not the best, uses 4 pipes!
