리눅스 / 명령어 / which, whereis, locate - 명령어 위치 찾기

 

www.manualfactory.net/10837

 

 

 

 

명령어의 위치를 찾을 때 사용할 수 있는 명령어에는 which, whereis, locate가 있습니다.

명령어의 위치만 찾을 때는 which를 사용하고, 관련된 파일들의 위치까지 찾을 때는 whereis나 locate를 사용합니다.

 

 

 

 

각 명령어로 find 명령어를 찾아보겠습니다.

 

[root@localhost ~]# which find

yum install mlocate
