Create Linux page

[osoderholm]

The Linux page should contain the following:

• [x] Basic info
• [x] Basic commands
• [x] Useful links (at least to TUXEDO.md and old intro slides)

Maybe also add some exercises?

Using tabs!

Process management

Basic commands:

Files/Directories:
    * ls - list files in directory
    * cd - change directory
    * rm - remove file/directory
    * cp - copy file/directory
    * mv - move file/directory
    * mkdir - create directory

Text editors:
    * vim 
    * nano
    * gedit

Networking:
    * ping - send a ping to an address
    * ssh (also in TUXEDO.md) - remotely connect to a computer
    * ifconfig - network interface configuration/info
    * iwconfig - like ifconfig but dedicated to wireless

• man
• top - terminal based task manager
• touch
• cat - read a file(s) and write to stdout
• echo
• grep
• pwd
• sudo - run program as another user
• whois
• whereis - search for location of file/program

Important to prioritise commands.

For now I suggest we close this issue, I think we should split this into basic commands and more advanced commands and add LinAnt's suggestions.
