| - | ''user@computer:~$'' '''/usr/bin/camera &'''
| + | |
| - | | + | |
| - | :Everything is run from a terminal, quite literally in *NIX. A GUI program is a running instance of a terminal process. Therefore the camera program can be launched. The & amperstand tells it to disassociate from the current terminal and create it's own process

| - | ''user@computer:~$'' '''ln -s /sbin/ifconfig /usr/bin'''
| + | |
| - | | + | |
| - | :The user PATH does not include /sbin for some reason by default on NITs, which is annoying as typing in /sbin/ifconfig - which should be in /usr/bin/ anyway. Thus we are going to symlink it.

| - | | + | |
| - | ''user@computer:~$''''' ifconfig | grep "inet addr"
| + | |
| - | | + | |
| - | :Example use of grep. grep outputs the entire line matching the pattern, in this case "inet addr" which is piped into it from the output of ifconfig using the | pipe character
| + | |
| - | | + | |
| - | | + | |
| - | ''user@computer:~$'' '''ifconfig | grep "inet addr" | awk '{ print $2 }' | cut -d : -f2'''
| + | |
| - | | + | |
| - | :Advanced example pipes from ifconfig to grep to awk and finally to cut to output the clean IP address which can then be fed into something else if desired
| + | |
| - | | + | |
| - | | + | |
| - | ==Logged in as root from here on out. Not necessary for every command but for some of them. If you have sudoer installed you can simply prefix each command with sudo. If not you are gonna use an equivalent of sudo su - or simply login a root using another method. For easyroot users, simply type $ root and enter.==

| - | :SSH example. Specify the user _at_ the IP address of the computer you want to access. Keep in mind that this works only over LAN by default (you need to forward port 22 on the router and give outside IP address or use some type of fake VPN). If you get a RSA error message, simply delete ~/.ssh/known_hosts using ''$'' '''rm ~/.ssh/known_hosts''' Type exit to leave remote session
