Sometimes it’s useful to write a bash script that do something like “Do this job, if it’s still running after XX second kill it”, how to implement this in a normal bash environment ?
Nothing simpler: Use the timeout shell command to achieve this.
From its info page:
timeout runs the given COMMAND and kills it if it is still running after the specified time interval
Let’s see how to use it.
I’m in the process of re-installing ArchLinux on my new Dell Latitude 6530, this is because at the end of the first installation I noticed that while running fdisk -l I received a message like this one (that’s not my original disk, but the message was the same):

I “shrinked” the original Windows 7 to 40 GB with Gparted live and created the partitions during the installation of ArchLinux with cfdisk so what’s wrong with these operations ?
While installing a new computer (soon a post on my new arch-linux laptop) I’ve re-discovered a command that I don’t use frequently, but that can be really useful : lsblk
lsblk lists information about all or the specified block devices. The lsblk command reads the sysfs filesystem to gather information.
The command prints all block devices (except RAM disks) in a tree-like format by default.

Check constantly your disk or its partitions is one of the essential things in a linux system. Today users usually checks this through graphical tools, but the real Linux old-timers use a terminal and the command “df“. Today I want to show you how to use “dfc“, similar to df but with the addition of colors and a percentage bar. You know, sometimes the eyes wants their part!
