This week’s command is: useradd.

This command is used to add new users to your linux system. The syntax is as follows:
useradd [options] [user]

The following was taken from a great site for learning about linux commands(ss64.com) and will further explain the command:

OPTIONS
-c comment Comment field.

-d dir Home directory.
The default is to use user as the directory name
under the home directory specified with the -D option.

Wow, this is crazy. Here it is

Kyle and I are going to be starting a podcast in the near future called Cit3.

We’ll be talking about anything related to the previous week.

More about this later,

This week’s command is: alias

This command is great. In short it allows you to create Pseudo commands.

For example, on the server that this site runs on (my server), I regularly need to check to see what connections my computer has initiated, and what services they’re through. I do this using the linux command netstat using the following command line string: “netstat -pan | grep tcp“. Since I’m not doing this blog on netstat I will not explain that to you. If you have any questions, just comment on this post below and either me(Jon) or Kyle will attempt to explain it to you.

Alright, I told you that I’d be posting another quickie on screen so here it is.

There’s not much more to talk about that’s relevant, except for one piece.

Restoring from saved sessions:
In order to view the saved sessions enter screen -r. you should be presented with a list of available sessions.
To restore a session enter the following command: screen -r SESSION_NAME.

That’s pretty much all that you need to know.

The guys at The Original Talk Like A Pirate Day Site have created thier own holiday. Talk like a pirate on Monday, September 19. This’ll be my first year taking part in it, and I’m sure I’ll have fun. Who knows… you might too.

A friend of mine is going to be posting stuff up here periodically. His name’s Kyle Smith. He’s a smart guy, and should make some good contributions to the site.

From The Gallery Website

“We are incredibly pleased to announce the release of Gallery 2.0! Over three years of design and development have gone into creating the best online photo management product possible. Gallery 2.0 is the natural successor to Gallery 1, and we hope that you like what you see. Don’t wait, download Gallery 2 now!”

I just installed it, and it was a breeze, I should have a link up here in a little bit.

This week’s command is: screen

I actually just found this command recently. It’s a great little treasure that expands the use of unix in a huge way. Let me explain.

For those of you who don’t know, Unix uses a CLI (or Command Line Interface), meaning that there are no “windows” or “X” boxes to close the windows, it’s all handeled by the keyboard and text on the screen.

Multitasking is critical with computers, and until recently, I’ve been cheating by opening up separate windows in my SSH (or Secure Shell) client. This can be a little bit tiring because you have to connect to the server each time you make a new window.
