That's probably because what I provided isn't a complete script, but rather an example of what it would look like when done manually. Posting again with comments to clarify:
Code:
> cat pass # Run the 'cat' program to show the contents of file 'pass' which
# contains the passphrase
s3cr3t # Contents of file 'pass'
# Calling gpg in batch mode, telling it not to allocate a TTY, asking for
# ASCII-Armor output (non-binary data), providing the passphrase in file 'pass',
# symmetric enryption for file 'test.file'
> gpg --batch --no-tty --armor --passphrase-file pass --symmetric test.file
> ls test.* # Display a listing of the original & encypted file
test.file test.file.asc
> file test.file.asc # Run the 'file' utility to take a guess at the type of the
# content of file 'test.file.asc'
test.file.asc: PGP armored data message # It tells us that it's encrypted,
# armored data
All you have to do is substitute the filenames I used with those you have. As soon as you've got that down, start using variables instead of filenames. And when that's done you can start with the for loop.
