The --passphrase-fd lets you specify any file descriptor as the source of
the passphrase. "0" is stdin. You can send the passphrase through other file
descriptors if you need to use stdin for your data.

echo secret  | gpg -e --passphrase-fd 0 .......

Searching the list archives for passphrase && stdin should give you a wealth
of examples for just about any environment. 'passphrase' alone in the
subject line produced around 340 matches.

Although, if your going to save this command if a file somewhere, you'd be
probably just as safe, and have an easier time implementing, if you used a
key with no passphrase. 8-}(
