The Original recomended systemd method dosn't work for me; trying to execute a systemd service from a script but bormatic ask for password passphrase when executing a backup.
I would love to use an alias with something like Pass( The Linux Pasword Manager ) in the lines of:
pass_import=pass show borgmatic | head -n1
that would promp for my master password and grab the password for my encypted borgmatic passphrase... thing is is it possible to pass that to borgmatic so it dosent need user input during execution?

borgmatic version: [1.5.10]

borgmatic installation method: [AUR]

Borg version: [1.1.13]

Python version: [3.8.5]

operating system and version: [Arch Linux]

Thanks for the question! Have you tried the encryption_passcommand option? It would look something like this in borgmatic's configuration:

storage:
    encryption_passcommand: "pass show borgmatic"

However, I don't believe the | head -n1 portion will work, because Borg doesn't support running actual shell commands like that to get the passphrase. However, Borg does have an example using pass directly: https://borgbackup.readthedocs.io/en/stable/quickstart.html#passphrase-notes

So maybe give that a shot, and if that doesn't work, Borg's documentation needs updating to show a working pass example (if possible)?
