I just discovered alt-scroll just by accident.

  Desktop Zoom (Xubuntu/Kubuntu): In Xfce (Xubuntu) and KDE (Kubuntu), Alt + Scroll is the default shortcut to zoom in and out of the entire desktop. This is an accessibility feature used to magnify specific parts of the screen.

Also I have "make-icon" to bragg about:

  convert  -size 24x24 -gravity center -background yellow -fill black\
     label:$1 ~/.local/share/icons/$1.png
  file=~/.local/share/applications/$1-noko.desktop
  echo [Desktop Entry] > $file
  echo Name=$1 >> $file
  echo Comment=noko-made >> $file
  echo Exec=$1 >> $file
  echo Terminal=false >> $file
  echo Icon=~/.local/share/icons/$1.png >> $file
  echo Type=Application >> $file

What exactly do we see here?

A shell injection vulnerability ad soon as somebody copies the same approach somewhere else or trained your LLM on it.

Write correct code by default, always, otherwise it will end up somewhere you care about.

The best way to do that is to avoid shell, as a language that makes writing insecure code the most convenient.

(The original intent looks like it's making a desktop/launch icon, e.g. you might call it with "firefox" as an argument and it would put its logo into an application starter, provided a logo of the correspond name is already in the place the script expects.)

Erh? Bash-reading disability?

make-icon ABCD:

1) Makes a small picture ABCD.png from the first letters of the string "ABCD".

2) Makes ABCD application icon to using the picture ABCD.png.

3) Moving youres pointing device on that icon and pressing appropriate button now executes ABCD.

"convert" is from Imagemagick of course.

    cat <<EOR > "${file}"
      [Desktop Entry]
      Comment=Bash has heredocs.
    EOR

I think the reason they are confused is that this is entirely out of context.

Neat! Does someone know a way to implement this in hyprland?

Nobody knows. I wanted preset zoom for watching widescreen movies on laptop. But xev does show anything at alt-scroll.
