Linux Commands for Beginners 09 - Understanding Permissions

permissions in Linux you know it's one of those things that's actually somewhat difficult to explain because the way that permissions are handled in Linux are you know it's a bit different than you know Windows for example and what I want to do or at least attempt in this video is to explain that to you guys so that you'll understand how to read the permission string inside your Linux system so let's go ahead and dive right in so here we have my laptop again and I'm goin g to go ahead and sho and show you guys my file listing in my home directory nothing too amazing here but I want to basically go over the permission string but we also need some files so I'm going to use a touch command I'm going to do test1 dot txt and then I'll do test2 test three and so on so you see we have a few files here we also have a bunch of folders so I want to go over what all of I've mentioned before that the first character in this case is D on this line refers to whether or not as a file or a directory now sometimes I'll say folder when I mean to say directory you know I use that interchangeably but file you know folder directory same thing so we know bin is a directory or a folder it starts with D in fact all of them do until you get down here where we have test123 which is simply just a - a - means file as I've mentioned previous in the series you know most of the time files are colored white folders are blue and colorization changes from one terminal emulator to the next but some distributions actually don't even colorize output so how does that work so alias LS this is the alias that I'm using for my LS command and most distributions will use color Auto as part of their alias by default so when you first install your distribution and then you create a user account for the default bash RC includes maybe not everything that I have here but it will almost always include this part right here so that basically sets up the colorization if I remove that line or that section here
