CentOS 리눅스 wget 설치하기 . 사용법(..이어받기..)

 

얼마전에 리눅스 사용중에 파일 다운로드가 필요하여

wget 명령어를 알게 되었습니다.

 

■ wget

인터넷을 통해 파일이나 디렉터리를 다운로드 할수 있는 기능입니다.

 

그런데 wget 명령어를 실행해보니 명령어를 찾을수 없다고 하네요.

[root@localhost ~]# wget -bash: wget: command not found [root@localhost ~]# man wget No manual entry for wget

 

CentOS7 minimal (최소) 버전이라 설치가 안되어 있어요.

yum 으로 일단 설치부터 합니다.
