====== Permissions ======
Created lørdag 22 oktober 2016

**#** **To change permissions of a file/folder, use** //chmod//
$ chmod //who=<PERMISSIONS> <FILE_NAME>//

**#** **Who  **
	u **= user that owns the file**
	g **= group the file belongs to**
	o **= other users (everyone else)**
	a **= all of the above (use instead of ugo)**
	
**#** **Permissions **
	r **= read access**
	w **= write access**
	x **= execute-able**


== Basic Examples ==
$ chmod og=rx ~/Documents          **# owner and group gets read and execute access**
$ chmod g=	~/Documents            **# no access for group (empty space means no access)**

**#** **You'll sometimes see numeric given permissions**
	r = 4	w = 2	x = 1
	
**#** **So as an example, we could say **
	[owner] : rwx = 4+2+1 = 7
	[group] : r-x = 4+0+1 = 5
	[other] : r-x = 4+0+1 = 5

**# Would be produced as**
$ chmod 755 //<FILE_NAME>//

== Bulk chmod ==
# **chmod directories to 755**	//-type d//  **for directory**
$ find //directory// -type d -exec chmod 755 {} +

**#** **chmod files to 644 **//-type f//	**for files**
$ find //directory// -type f -exec chmod 644 {} +

== Change ownership ==
**# Let's say we have a folder owned by **//root//** - maybe we created a new partition with **//gparted//** ex.** 
$ chown //username// /path/to/folder
