Re: Calling PASE command in batch

Then, something like this might work:

#!/bin/sh

build_script() {

cat <<End-of-message
#!/usr/local/bin/expect -f
spawn /QOpenSys/usr/bin/gpg
expect {
default {exit 2}
"Enter passphrase:"
}
send "${PASSPHRASE}\n"
}

build_script | /usr/local/bin/expect -f -


You will need to adjust the spawn command for the location of gpg on your
system.

You may need to expand the script, depending on what gpg prompts for, as well.

GPG displays "Enter passphrase: "

I just read a little closer. Not sure if this works:

echo {$PASSPHRASE} | gpg (Assume the passphrase can come from stdin)

You might also need to use an expect script to get the password into gpg.
Not
sure as I have not used that command. Try the simple echo first. If that
doesn't work, what string does gpg display when it requests the pass
phrase?
