Unlock keyring in (headless) scripts

[khufkens]

To start a script as a batch job you will need to pass the keyring password and unlock the keyring for this session. In the past this would trigger an interactive prompt but for 'reasons' this seems not to work anymore. This is a workaround.

#!/usr/bin/env Rscript
args = commandArgs(trailingOnly=TRUE)

library("ecwmfr")

# set file based keyring and unlock with argument
options(keyring_backend="file")
keyring::keyring_unlock("appeears", args[1])
