Nemo Action updating

In a terminal navigate to the sgs.nemo-actions folder created when you originally cloned the repo

e.g cd sgs.nemo-actions

Once in the correct folder update your local copy with the latest commits, before reinstalling your actions.

git pull origin; cd ..

Debug

nemo -q; NEMO_DEBUG=Actions NEMO_ACTION_VERBOSE=5 nemo --debug

Write an action

To make scripts executed to multiple files with a progress bar, use bash_action.sh. Simple example:

• execute ls command on each selected files: Exec=<scripts/bash_action.py "ls {}" %F>
• same effect, but adding a bash variable: Exec=<scripts/bash_action.py "filename={}; ls \"$filename\"" %F>

Take a look to existing actions. Particularly flac_to_wav.nemo_action is a simple real-world example.

To specify icon you can use Icon-Name. Available icons are located in /usr/share/icons/gnome/32x32/actions.

Debug actions (show actions logs and Nemo errors about actions)

nemo -q; NEMO_ACTION_VERBOSE=1 nemo --no-desktop

Some tricks:

• the space between " and %F> is important; ie "%F> will not work
