I am trying to change the "custom-command" value for the Tilix terminal emulator in dconf from
python3 $HOME/Scripts/memux/main.py to
python3 $HOME/.pps/pecan.py, but I can't figure out the format for use with the dconf command line tool, and gsettings seems to lack the functionality to change a single setting of a key. Using the GUI is not an option. I did rtfm, and the last argument needs to be a string in "GVariant format".
dconf write /com/gexperts/Tilix/profiles/2b7c4080-0ddd-46c5-8f23-563fd3ba789d/custom-command (some-argument)
Running the above command with no final argument results in the following.
error: value not specified Usage: dconf write KEY VALUE Write a new value to a key Arguments: KEY A key path (starting, but not ending with '/') VALUE The value to write (in GVariant format)
How do I format the string so that dconf accepts it? Or, if there's another better way, how do I set the value via that? Below is a pair of screenshots with the GUI dconf-editor page containing the value I need to edit, if that helps.
