Jude_Juu 2023. 10. 24. 11:39

리눅스 환경에서 명령프롬프트를 실행시키는 프로그램 UBUNTU에서 cal 툴을 사용하려고 할 때,

명령어가 실행이 되지 않을 때가 있다.

mj@ubuntu:~$ cal
Command 'cal' not found, but can be installed with:
sudo apt install ncal

이러한 경우는 bsdmainutils 설치를 해주면 금방 해결이 된다.

1. sudo apt-get update -y

2. sudo apt-get install -y bsdmainutils

1. sudo apt update

2. sudo apt install bsdmainutils

3. Do you want continue? [Y/n] - y

mj@ubuntu:~$ sudo apt-get update -y
