 +==== Superuser ==== 
 +=== Execute sudo cmd without needing to type password === 
 +== Staying Safe == 
 +  - backup ''/etc/sudoers'' file i.e. copy to somewhere safe 
 +  - leave at least one terminal window open as root 
 +  - edit ''/etc/sudoers'' with ''visudo'' not ''sudo''. It's a wrapper for your already configured editor (not necessarily vi) 
 +== The Magic == 
 +  * create a wrapper script that does all your magic for you. Don't add sudo to the cmds in the wrapper script 
 +  * using ''visudo'' add to the end of your ''/etc/sudoers'' file ''USERNAME ALL=(ALL:ALL) NOPASSWD: FULL_PATH_TO_SCRIPT'' substituting in USERNAME and FULL_PATH_TO_SCRIPT as necessary 
 +  * to execute the cmd without password type ''sudo FULL_PATH_TO_THE_SCRIPT''
