then in your script, write
gpg --passphrase-fd=0 rest_of_command_specs <secret
I will probably end up doing this, but I am interested if there is any
way to securely take data from a bash variable and put it to a file. Is
there a write function? I would normally use echo, but that is not
secure. Is this a task that is beyond bash?
bash has it's own bultin echo, in case your security concern was the
fork()/exec() ?
