@SGS thank you for the command to list timers, much appreciated.
@filo thank you very much! These are a lot of useful infos and you were right, it was an environment variable issue.
So, I can say for sure that I posted in the right section: I’m such a newbie!
‘crontab -e’ command opens Keta editor 'cause a global environment variable is set to use Keta text editor.
Now the fun part, I come from Debian, where by default you find Bash shell, so… I was trying to use Fish shell as Bash, but this isn’t how things work.
I opened:
~/.config/fish/config.fish
and configured:
set -g EDITOR /usr/bin/nano
set -g SUDO_EDITOR /usr/bin/nano
set -g VISUAL $EDITOR
So this is the Fish shell equivalent of setting environment variables inside ~/.bashrc (on Bash).
I edited crontab -e with ‘nano’, thus the temporary file (crontab.something) acts correctly as a buffer, inside I wrote:
@reboot rclone mount --daemon GDrive: /home/elia/DB/
Saved with Ctrl + X and reboot.
My Google Drive was successfully mounted at boot.
This lookslike to me a little bit “dirty” as solution, so I’ll definitively give a try to the systemd service way you pointed me. For now, a big thank you!
