This week’s command is: uname

This command is used to list out miscellaneous information about your system.
The syntax is as follows: uname [OPTION]...

I usually use this to find out exactly what kernel release I’m using. (no, I’m not geeky enough to memorize each kernel that I use)

Here’s the usage (taken from the console with modification):
-a, --all print all information, in the following order: -s, --kernel-name print the kernel name (for me this prints Linux) -n, --nodename print the hostname of your computer -r, --kernel-release print the kernel release number -v, --kernel-version print the kernel version -m, --machine print the machine hardware name (for me this prints i686) -o, --operating-system print the operating system --help display this help and exit --version output version information and exit

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.

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.
