This is a small collection of "Nemo actions", which are basically small executable scripts that are visible as options in the right-click menu of the Nemo file browser.
Nemo is the default file browser of the Cinnamon desktop environment, which is the default in Linux Mint.
"Installing" these scripts is done by placing them in one of the following folders:
~/.local/share/nemo/actions/- Placing them here will make them available only for the current user.
/usr/share/nemo/actions/- Placing them here will make them avilable for everyone on the system.
A quick git clone command can look like this:
git clone git@github.com:JonasAlfredsson/nemo-actions.git ~/.local/share/nemo/actions/A detailed example of a Nemo action file can be found in the official
repository, and as usual the ArchWiki provides additional useful
information to the subject at hand. So I suggest you check that out both of
these if you want to create your own custom actions. The only thing to remember
is that all files need to have .nemo_action as their file ending, otherwise
they will not be recognized by the file browser.
