Since I acquired a hosting plan, with the great Dreamhost team, I’ve been creating some websites, experimenting with stuff, login in, login out, via terminal ssh and also using CyberDuck sftp client for Mac. And, even though I use Linux for a while now, sometimes laziness takes his best, and it seems like my brain goes numb! Let me explain… Every time I login on my server space, I type a username (if I’m in the terminal this part is skipped, because local user is the same in the remote server, thereby no need to specify user) and a password. This is cool, if you do it one or two times a day, but if you keep doing this a lot, and have a bunch of servers (working in system administration can do this for you =] ) to login, you will get tired typing all this username/passwords all the time!

Keep reading so I can change your opinion! (or not…)
To change file permissions, you simply need to know the chmod command. Its simple to learn, and there are two different modes to use it: a symbolic mode and a numeric mode. By now you have some hints, on how to use a little of both, so now we get into detail.
