Quand on travaille régulièrement sous Linux, il est intéressant de savoir quelles commandes on utilise le plus souvent. Cela peut vous aider à optimiser vos alias, automatiser certaines tâches ou tout simplement mieux comprendre votre utilisation quotidienne.
history | awk '{print $2}' | sort | uniq -c | sort -nr | head -10
Explication étape par étape :
history : affiche l'historique des commandes que vous avez tapées dans votre terminal
awk '{print $2}' : avec awk, on récupère uniquement la deuxième colonne, qui correspond à la commande (le premier mot)
sort : trie toutes les commandes par ordre alphabétique
uniq -c : compte les occurrences de chaque commande
sort -nr : trie numériquement (-n) et en ordre décroissant (-r), pour avoir les plus fréquentes en premier
head -10 : affiche uniquement les 10 premières lignes, soit les 10 commandes les plus utiliséesVous pouvez aussi modifier la commande pour compter non seulement le premier mot, mais toute la ligne de commande (exemple : git status vs git pull). Dans ce cas, remplacez awk '{print $2}' par awk '{$1=""; print $0}'. Ce qui donne :
history | awk '{$1=""; print $0}' | sort | uniq -c | sort -nr | head -10

In short, we're just a bunch of geeks. Back in 2016, Star Labs was formed in a pub. We all depended on using Linux, all with different laptops and all with different complaints about them. It always perplexed us that a laptop had never been made specifically for Linux. Whilst many had been "converted" to run Linux - they seldom offered the experience that macOS and Windows users had. So, after a few pints, we decided to make one.

If you need to downgrade the Kernel version on Ubuntu Linux, here's how you can safely do this with the linux-image and related packages.
ck@ubuntu:~$ dpkg -l|grep linux-image
ii linux-image-5.15.0-73-generic 5.15.0-73.80 amd64 Signed kernel image generic
ii linux-image-5.15.0-75-generic 5.15.0-75.82 amd64 Signed kernel image generic
ck@ubuntu:~$ grep TIMEOUT /etc/default/grub
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
Change the values to:
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=5
Followed by the command sudo update-grub. At the next system (re-)boot, the GRUB menu should show up.

wmctrl -r Firefox -e 0,110,15,1450,1030
Anyone knows a good way to resize any window to for example 640x480?
Reason is, of course, screencasting.
Under windows I've used ZoneSize from donationcoder. (Btw: For Firefox it's easy, just us...
Use the wmctrl command:
To list the windows:
$ wmctrl -l
0x00c00003 -1 rgamble-desktop Bottom Expanded Edge Panel
0x00c00031 -1 rgamble-desktop Top Expanded Edge Panel
0x00e00022 -1 rgamble-desktop Desktop
0x0260007c 0 rgamble-desktop Google - Mozilla Firefox
To resize a window based on its title:
wmctrl -r Firefox -e 0,0,0,640,480
The arguments to the resize option are gravity,X,Y,width,height so this will place the window at the top-left corner of the screen and resize it to 640X480.
Linux Window Managers quietly control app windows, ensuring their appearance and arrangement, working in the background of your OS.

xdg-open {file | URL}
Delete the file /usr/share/applications/wslview.desktop.
I hit this too on a fresh Ubuntu 22.04.1 LTS release.
I deleted the file /usr/share/applications/wslview.desktop and xdg-open started to work as expected.
I don't know what exactly happens but it seems that the wslview.desktop launcher is meant for using Ubuntu in Windows WSL. But for some reason it's launched for every xdg-open invocation. When it's removed, xdg-open will use another launcher associated with the URL, the correct one.
