OK- it looks like you are using Zorin Lite- which is XFCE. Application Finder is only on Zorin Lite.
In Gnome- it would restart the Gnome-Shell (Zorin Core and Zorin Ultimate).
My hats off to you for choosing Zorin Lite. It is a great desktop.
To restart the panel in XFCE or Zorin Lite, enter into Alt+F2 instead
To restart the Desktop in XFCE or Zorin Lite, enter in:
That being said… The only reason I could possibly see to place the
mv ~/.local/icons/AltGr.png ~/.local/icons/AltGr0.png
within its own bash script would be if you wanted to constantly rotate the icons out with eachother in order to create an animated desktop icon.
Which Would Not Work, By the Way.
If all you want to do is to replace the icon- then enter the applicable mv command into your Terminal. Replace the icon with the new one… One Time Only… Then use Alt+F2 to
or restart the panel in order to see the changes.
And for the Curious - Since the suggestion was made by me asking if the OP was trying to create an animated icon: No, that cannot be used to create an animated Icon on the desktop- before anyone starts asking. For one thing, either Gnome-Shell or XFCE4panel would need to be constantly restarted and that would not only be bad for the system after a while, but it would also bog the system down to the point of being unusable.
IF I wanted to create an animated Icon on my desktop, I would probably use a Lua Script to make an animated Conky that is background, then place a Transparent Icon on top of it. (And this may not even work on the New XFCE due to how XFCE changed how it handles desktop transparency.)
Bash Scripts are used for Repetitive or Repeatable actions, not for a one time change.
