나는 로그인하고 호스트 이름 정보를 얻기 위해 pexpect.py 스크립트를 사용하고있다.
는 기본적으로 난 당신이 몇 가지 명령을 실행하고 닫으려면 자동화 된 사용자들은 아래에 볼이파이썬 Pexpect SSH 명령 줄 로그인 인수
~$:./pexpect.py -h{hostname} -u{user} -p{password}
처럼 실행합니다. 마지막에 줄을 추가하여 사용자가보고 싶은 정보를 선택할 수 있도록하고 싶습니다. .. 기본적으로
~$:./pexpexct.py -h{hostname} -u{username} -p{password} -x{user defined} -z{user defined}
-x 존재와 목록의 가동 시간과 -z 존재 ifconfig를 ..도있을 것입니다 -a, -b, -c 말 : 그래서 그 대신 위의 명령 라인의 그것과 같을 것 . 나는이 코드에서 인수를 추가하는 방법으로 잃었어요 :이 라인에서
