Since I use computer from start, I still can’t remember the command line even in Windows. I mean I always look up on Google for the commands. I have tried some (not many) Linux distros, sometimes things work differently in different Linux. It is same with my programming syntax. I don’t remember much. Every time I just copy and paste. ?
Most of the time in Linux, things to know are:
Using sudo
chmod
cd and ls
Other commands just look up from the Internet ?
Things that I always get confused:
Check IP address.
In Windows, we use ipconfig
Ubuntu, ifconfig
Sometimes ifconfig is not ship by default
So there is “ip a”.
There is another skill to learn in Linux is using the desktop environment.
In Ubuntu 20.04, it is easy to create a launcher (shortcut on desktop)
Recently I tried with Debian 11, not sure there is a bug in Gnome 40, it is more difficult. By default, Desktop icons are not available now. I have to enable it by Gnome Tweaks. There are many things that are more difficult to do in recent updates. I don’t know why.
Recently I found Debian is a little bit faster to boot up and lighter in RAM usage. Ubuntu is easier to use but it took 2 minutes 30 seconds to reach the GUI compared to Debian 1 minute in a very old machine with Celeron duo core and 2 GB RAM. I learn to analyze the startup process and disable some processes to speed up the booting. If you are developing B4J GUI app and using openjdk 11 JFX, switch to X11 or Xorg session otherwise it won’t run since Gnome load with Wayland by default.
