Look at the --passphrase-fd, --passphrase-file, or --passphrase
options.  They are all in the manual, and can be used to provide a
passphrase during batch operation.

However, if you are including the passphrase in a script, it is worth
asking yourself if there is any security benefit in having a
passphrase-protected key at all.  After all, an attacker who gets
access to the script needs merely to read it to know the passphrase.
