What is something *new* you have learned about Linux within the past 7 days?

I'm not sure how I missed it but xargs has an option for parallel processes, the -P option. I had gone so far as to install and learn GNU Parallel instead.

I just learned that then shell redirection operator > calls openat() with O_WRONLY | O_CREAT | O_TRUNC.
The The call that uses >> would replace O_TRUNC with O_APPEND.

Happy New Year, best wishes to you and yours.

TIL I can run weston in a tty while running an X11 desktop, and run wayland stuff there including waydroid, just switch back and forth with ctrl-alt-fkey.

When one does something like:

Code:

$ eject      # Open drive and place CD media in it
$ eject -t   # Close the drive

If I then begin typing in the terminal window, when the drive "settles down" and recognizes that there's media present, I lose input focus in that terminal window as though I'd clicked somewhere else on the desktop. Not sure what causes this -- I'm using KDE/Plasma on OpenSUSE so it could be part of the notification subsystem -- but I've had to retype so many commands when this happens. :^D

Very likely. There is a slight, unexpected delay with media notifications on my Plasma desktop. That means they end up popping up at the wrong time when I connect a device, and like in your case, the notification steals the focus. Fortunately it hasn't caused major damage.

I just discovered axi-cache,
the Apt Xapian Index Cache command.
It is a local fulltext search engine for debian packages,
apparently used by aptitude,
(it was installed by aptitude)
with far better results than apt-cache search.
Compare this

Code:

$ apt-cache search "role playing game"
gearhead - roguelike mecha role playing game
gearhead2 - roguelike mecha role playing game in space
rolldice - A virtual dice roller
$

to this

Code:

$ axi-cache search "role playing game"
26 results found.
Results 1-20:
100% freedink-data - adventure and role-playing game (game data)
97% freedink-engine - adventure and role-playing game (engine)

Today, I learned viewing YAML files in vim, set these in .vimrc (or in vim) to make it easier

Code:

set cuc
set cul

I've learned that I've been shorting myself of a great chance to learn a lot about Linux by putting off the exercise of installing SlackWare for fear of lack of having a GUI to lean on. I've also learned that when OpenSuse doesn't work on my Workstation however, it works like a charm on the old Laptop that my father gave me which was his employer issued laptop.

or you could learn that you can install just about any Linux in a virtual machine. i suggest Linux From Scratch.

I learned to stop wining about xterm not returning the return-values of an executed program (xterm -e).
Giving in to using temporary files and unlink, I have to admit that there is probably nothing wrong with that. Also, I venture that whichever programming-language you use, that

Code:

IO::popen

is a gift from above.

I learnt more about Linux in 6 months after installing Slackware than the previous 2 years of using Ubuntu.
Why do you think that Slackware doen't have a GUI? Xfce and KDE are both included in the installer.

I now use LFS instead of Slackware but I could never have built it without what I learnt from Slackware.

But could you have learned so much with Slackware without the previous 2 years of Ubuntu experience?
