gpg --export
or
gpg --export-secret-key

"--export Either export all keys from all keyrings (default keyrings and
those registered via option --keyring), or if at least one name
is given, those of the given name. The new keyring is written to STDOUT or to the file given with option --output. Use together
with --armor to mail those keys."
