이전 버전을 가리키는 방법은 무엇입니까?

내 서버의 기본 gpg는 1.4.20입니다. 하지만 몇 가지 실험을 수행하려면 gpg 버전 1.4.13을 설치해야 합니다.

다음 명령을 실행합니다.

   ./configure 
   make 
   make install

이 시점에서 gpg는 기본 디렉터리( /usr/local/bin/gpg)에 설치됩니다. 을 사용하면 gpg --version가리키는 버전이 이라는 것을 알 수 있습니다 . 원래 1.4.20 버전( 폴더 1.4.13아래)을 가리키기를 원합니다 . /usr/bin/gpg어떻게 해야 합니까?

(base) :~$ type gpg
gpg is /usr/local/bin/gpg
(base) :~$ gpg --version
gpg (GnuPG) 1.4.13
