Accept shell command parameters to automate things

[razum2um]

Hi, I definitely understand the purpose of 2FA, but I really need to automate some things in my workflow:

# using `gopass` (gpg-encrypted passwords in a git repo)
gopass show -f -o '...'
# and a separate host for 2fa secrets like that
ssh user@host 'oathtool --totp -b $(cat secret)'
