• man 1 'gpg' [EN]

Parameters

–verify [[SIGFILE] [FILE ...]]

Assume that SIGFILE is a signature and verify it without generating any output. With no arguments, the signature packet is read from stdin (it may be a detached signature when not used in batch mode). If only a SIGFILE is given, it may be a complete signature or a detached signature, in which case the signed stuff is expected in a file without the .sig or .asc extension (if such a file does not exist it is expected at stdin; use a single dash (-) as filename to force a read from stdin). With more than 1 argument, the first should be a detached signature and the remaining files are the signed stuff.

Example

Verify the signature of a downloaded file

gpg --verify "install-x86-minimal-20141007.iso.DIGESTS.asc"
