# Linux Commands

Hope you have installed Ubuntu Linux and successfully able to open Linux terminal.

Please Note: If you are using Windows OS, You can skip this step for now. But this commands will be used to play arround with ruggedBOARD-A5D2x. Because ruggedBOARD-A5D2x runs on Linux OS.

In your terminal, type

`Ubuntu@pc:~$ ls`

and hit enter.

The ls command, short for “list”, tells your computer to list all of the file names for the folder you are in

`Ubuntu@pc:~$pwd` 

and hit enter.   prints the current working directory.

Similarly Create your own Directory (Folder) called “Work”

`Ubuntu@pc:~$ cd ~`\
`Ubuntu@pc:~$ mkdir Work`

Change your directory to Work //cd means change directory

`Ubuntu@pc:~$cd Work`

In similar way  create  few more directories under “Work”  for  ruggedBOARD\
Ex:    `Ubuntu@pc:~$ Work/ls`

If you want to get more manual about any commands  use Command called “man”

Syntax : *Ubuntu\@pc:\~$ man command*

Ex : `Ubuntu@pc:~$ man mkdir`

Similarly follow the other commands to get more hands-on the Linux-OS

**Note**: *cd /bin*  -- you could find the all commands  which are available in Ubuntu-OS

*cp, mv , touch, find , grep, ps , chmod,......etc.*
