Here's a short summary of commands in PGP 2.6.2i:

Generate new key pair:  pgp -kg
Add key:                pgp -ka     keyfile           [keyring]
Extract key:            pgp -kx[a]  userid   keyfile  [keyring]
View key(s):            pgp -kv[v] [userid]           [keyring]
View fingerprint:       pgp -kvc   [userid]           [keyring]
Check & view in detail: pgp -kc    [userid]           [keyring]
Remove userid or key:   pgp -kr     userid            [keyring]
                        (Repeat for multiple userids on a key)
Add another userid:     pgp -ke     userid            [keyring]
Edit passphrase:        pgp -ke     userid            [keyring]
Edit trust params:      pgp -kx     userid key.tmp    [keyring]
  (3 steps)             pgp -kr     userid            [keyring]
                        pgp -ka     key.tmp           [keyring]
Sign a key in pubring:  pgp -ks other_id [-u sign_id] [keyring]
Remove a sig from key:  pgp -krs    userid            [keyring]
Revoke, dis/enable:     pgp -kd     userid            [keyring]

Encrypt:                pgp -e[a]  textfile TO_id [TO_id2 TO_id3...]
Sign:                   pgp -s[a]  textfile                         [-u MY_id]
Sign & encrypt:         pgp -se[a] textfile TO_id [TO_id2 TO_id3...][-u MY_id]
Make detached cert:     pgp -sb[a] [+clearsig=on] mainfile          [-u MY_id]
  (Can do binaries)     (clearsig=on may be set in CONFIG.TXT)
Encrypt with IDEA only: pgp -c     textfile
Decrypt or check sig:   pgp [-d] [-p] cryptogram
                        (-d to keep pgp data, -p for original file name)
Check detached cert:    pgp certfile [mainfile]
                        (If root of filenames are the same omit [mainfile])

Use [a] for ASCII output
Use [-o outfile] to specify an output file
Use [+batchmode] for errorlevel returns
Use [f] for stream redirection ( pgp -f[ARGS] <infile >outfile )
Use [w] to wipe plaintext file (encryption operations)
Use [m] to force display of plaintext only (no output file)
Use [t] to alter line endings for unix, etc.
