LinuxAIOSometimes you want to test or show different GNU/Linux distributions, or just different desktop environment, and in these cases you usually have to put different ISO on CD/DVD or better on USB Sticks and this usually take some time. Luckily now there is a new and nice project that makes the work of testing different distributions much more easy: the Linux AIO (All In One) project.

From the Linux AIO website:

Our plan is to bring some of the major Linux distributions (Ubuntu and flavors, Linux Mint (“Debian”), Debian Live) with different desktop environments on one ISO file that can be burnt on one DVD or USB flash drive. Every one of them can be used as Live system, with no need of installation on hard drive or can be eventually installed on computer for full experience.

If, like me, you work on terminals connected via ssh to remote computer/server you are probably used to tmux and screen and so it’s not a problem if you have to close your session, as you’ll be able to easily re-connect when you need it, but sometimes you could forget about using one of these utility.

Started a long-running process over ssh, but have to leave and don’t want to interrupt it?
Just start a screen, use reptyr to grab it, and then kill the ssh session and head on home.

Sometimes it’s useful to know which components you are using on a GNU/Linux computer or server, you can go with the long way, taking a look at the boot message for all the hardware discovered, use some terminal commands such as lsusb,lspci or lshw or some graphical tools such as hardinfo (my favourite graphical tool) or Inex/CPU-G.

But I’ve discovered on my Linux Mint, that, by default, I’ve now a new option: inxi

inxi it’s a full featured system information script wrote in bash, that easily will show on a terminal all the info of your system.

Tee

The command “tee” it’s one of the basic commands that you should find in any system, yet it’s not so popular or use, this command reads standard input and writes it to both standard output and one or more files, effectively duplicating its input.
