eliminates "l" and "o" characters change length by changing 'x' here: cut -c 1-x

Values will depend on the driver and the hardware specifics, so you need to refer to your driver documentation for proper interpretation of those values.

Very simple and useful, you need to change the word "directory" for your directory

This deals nicely with files having special characters in the file name (space ' or ").

Parallel is from https://savannah.nongnu.org/projects/parallel/

The preferred way for scripts (and easier to parse)

gets the last number of the mac address to use it for other stuff

I alias this as "tach":

alias tach='screen -x `screen -ls | grep Detached | cut -c -10`'

If you have several detached sessions it will just grab the first one. If you're running nested screens you can open new outer windows and run tach repeatedly to grab all the detached sessions into that one.

Gets the internal and external IP addresses of all your interfaces, or the ones given as arguments

--basic --user username:password

This will authenticate your Twitter username and password

--data status=""

Send data to the API with POST HTTP form.

Useful after a complete system update (without a new kernel) when you want to know, which processes need to be restarted

For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing.

WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.

A few characters shorter that the other command

I don't know why this ain't written as simply as it is. I always see it's just used as parameter, like: vi `!!`

But i use it to repeat a command, as i always work on several shells and check the result of one shell on a second.

these are some aliases you can use in bashrc to shorten the amount of typing needed to use apt-get, also can be used as reference if you can't remember alot of commands or command parameter variations,etc...

Please comment with more apt-get aliases if I missed any, thx

possible options:

* Varnish

* Squid in reverse proxy mode

* Django's cache framework

* rack-cache

* or CDN, like Akamai

curl doesn't provide url-encoding for 'GET' data, it have an option '--data-urlencode', but its only for 'POST' data. Thats why I need to write down this commandline. With 'perl', 'php' and 'python', this is one liner, but just I wrote it for fun. Works in Ubuntu, will work in all linux varients(I hope it will work in unix varients also).

This will temporarily add the current directory to your $PATH. Allowing you to execute from that directory for the duration of the session.

works like a charm for the K610i
