There appears to be several other too - DOC is right about the hundreds of switches!!:

pgp s (Sign Functions):
- -----------------------

pgp s [-u userid] [-bafqtvz] [-o file2 [-o ]]

PGP Sign file(s)

-a ASCII armoring
-b Detached signature
-f Filter Mode; Read from stdin to stdout
-o

Output file for most recent input file
-q Quiet mode
-t Text mode
-u UserID of the key you wish to sign with. May only be
specified once. If not specified, your default signing
key will be used.
-v Verbose
-z Batch mode (assumes no user interaction; not yet
implemented.)
-h Display this screen

--license Display usage license

pgp e (Encrypt Functions):
- --------------------------

pgp e [[-r -r ] [-s [-u ]] | [-c]] [-afqtvz]
[-o outfile1] [-o ]

PGP Encrypt file(s)

-a ASCII armoring
-c Conventional Encryption (IDEA only; is mutually exclusive
with -s, -u and -r)
-f Filter Mode; Read from stdin to stdout
-o

Output file for most recent input file
-q Quiet mode
-r UserID to encrypt to. May be specified multiple times.
-s Sign, as well as encrypt (use pgps to just sign). If no
userid is specified with -u, the default userid is used.
-t Text mode
-u UserID of the key you wish to sign with. May only be
specified once.
-v Verbose
-z Batch mode (assumes no user interaction; not yet
implemented.)
-h Display this screen

--license Display usage license

pgp v (Decrypt/Verify Functions):
- ---------------------------------

pgp v [-dfKmqvz] [-o file2 -o ]

Decrypt/Verify PGP encrypted and/or signed file(s)

-f Filter Mode; Read from stdin to stdout
-K Do not process any keys that are present (normally pgpv
will add keys to your keyring if found in an input file)
-m More Mode; display using pager rather than saving
-o

Output file for most recent input file
-q Quiet mode
-v Verbose
-z Batch mode (assumes no user interaction; not yet
implemented).

-h Display this screen

--license Display usage license

pgpk (Key Management functions):
- --------------------------------
To generate your own unique public/private key pair:
pgpk -g [ DSS|RSA ]

To add a key file's contents to your public or private key ring:
pgpk -a keyfile [keyfile ...]

To remove a key from your public and private key ring:
pgpk -r userid (or pgpk -rk userid)

To remove a user ID from your public and private key ring:
pgpk -ru userid

To remove a signature from your public key ring:
pgpk -rs userid

To edit your user ID or pass phrase:
pgpk -e your_userid

To edit the confidence you have in a person as an introducer:
pgpk -e her_userid

To extract (copy) a key from your public key ring:
pgpk -x userid -o keyfile

To extract (copy) a key from your public key ring in ascii form:
pgpk -xa userid -o keyfile

To list the contents of your key rings:
pgpk -l[l] [userid]

To check signatures on your public key ring:
pgpk -c [userid]

To sign someone else's public key on your public key ring:
pgpk -s her_userid [-u your_userid]

To disable or re-enable some else's public key on your public key ring:
pgpk -d her_userid

To permanently revoke your own key on your public and private key rings:
pgpk --revoke your_userid

To revoke a signature you made on someone else's key on your pub key ring:
pgpk --revokes your_userid

To view the license granted you:
pgpk --license

11.1 Are there undocumented features in PGP?

Several undocumented command-line switches exist. Peter Simons
has provided a comprehensive list:
* The "-i" option will cause PGP to include more information about
the file in the encrypted message. With the "-p" option, PGP
restores the original filename when you decrypt the message, but
if this option is also used, and both sender and recipient are
using the same platform, then the original file permissions and
timestamp will also be restored.
* With the "-l" option PGP gives lots more information about what it
is doing. During key generation, for example, you get to see the
actual numbers used in your public and secret key.
* The "-km" option will display the "web of trust" (see question
4.7) in a nested list. This way you can see which key introduces
which.
* By putting "encrypttoself=on" in your configuration file, all
messages that you encrypt will always be encrypted with your own
public key as well. This way you will be able to decrypt and read
every message you send. This can be useful if you have PGP set up
to encrypt every outgoing message, and your "outbox" will keep the
encrypted versions. Note: if someone else ever manages to obtain
your secret key, he will be able to read every encrypted message
you ever sent out, if this option was enabled.
* To create a file containing n random bytes, use the "pgp filename
+makerandom=n". There is a bug in the international versions of
PGP, which results in this random data being a lot less random
than normal.
