1. 프로세스 리스트 확인 : tasklist
1) 설명 : 프로세스 리스트를 보여준다
2) 입력 구조 : TASKLIST [/S 시스템 [/U 사용자 이름 [/P [암호]]]] [/M [모듈] | /SVC | /V] [/FI 필터] [/FO 형식] [/NH]
3) 기본 구성 : 프로세스 명, pid, 세션명 등을 보여준다
2. 프로세스 kill : taskkill
설명 : 개발을 진행하거나 하다보면 여기저기 튀어나오는 좀비들때문에 여간 귀찮은것이 아니다.
그럴때 프로세스를 죽일수 있는 명령어가 taskkill 이다
2) 기본 구성 : TASKKILL[/S시스템[/U사용자이름[/P[암호]]]] { [/FI 필터] [/PID 프로세스 id | /IM 이미지 이름] } [/T] [/F]
3) 주요 옵션
a. /PID 프로세스 ID : 특정 프로세스ID의 프로세스 종료하기
예시 : taskkill /PID 21500 -> 21500 PID를 가지는 프로세스 종료해라
b. /IM 프로세스명 : 특정 이름을 가지는 프로세스 종료(와일드카드(*) 사용가능)
예시 : taskkill /IM java* -> java로 시작하는 이름을 가진 프로세스 종료해라
c. /T : 지정된 프로세스와 그 자식 프로세스 까지 종료
예시 : taskkill /T /PID 21303 -> PID가 21303인 프로세스와 그 자식 프로세스 까지 종료
3. WMIC 명령어를 통한 부모 프로세스 찾기
wmic를 통해 보고싶은것만 찾아보자
-> wmic process where 항목="항목값" get 파라미터1, 파라미터2, 파라미터3
-> 프로세스 항목의 값이 "항목값인" 프로세스의 파라미터1, 파라미터2, 파라미터3 정보를 표시해준다.
예시) wmic process where name="chrome.exe" get processid, parentprocessid, commandline
-> 프로세스명이 chrome.exe인 프로세스의 pid, ppid, commandline을 볼수 있다.
