#gpg --list-keys user_ID

#gpg --fingerprint user_ID

#gpg --verify pgpfile

#gpg --verify sigfile

Verify the signature of the file but do not output the data. The second form is used for detached signatures, where sigfile is the detached signature (either ASCII armored or binary) and are the signed data; if this is not given, the name of the file holding the signed data is constructed by cutting off the extension (“.asc” or “.sig”) of sigfile or by asking the user for the filename.
