포고플러그 시리즈4에 아치리눅스 사용하기 (11) - 웰컴 메시지+컬러 쉘 적용하기

 

포고플러그E02용 김구스님 한방팩에 적용되어 있는 웰컴메시지 및 컬러쉘 화면 저도 참 좋아하는데요.

한번 적용해 보겠습니다.

 

밋밋했던 SSH 화면이 화려하게 바뀝니다.

먼저 혹시 모를 사고에 대비 bash.bashrc를 다른 이름으로 저장한다

 

mv /etc/bash.bashrc /etc/bash.bashrc.original

nano /etc/bash.bashrc

 

 

그리고 아래의 내용을 그대로 붙여넣는다. (putty 사용자는 마우스 오른쪽 버튼이 붙여넣기, 드래그는 복사.)

 

# /etc/bash.bashrc

#

# This file is sourced by all *interactive* bash shells on startup,

# including some apparently interactive shells such as scp and rcp

# that can't tolerate any output. So make sure this doesn't display

# anything or bad things will happen !

 

# Test for an interactive shell. There is no need to set anything

# past this point for scp and rcp, and it's important to refrain from

# outputting anything in those cases.

 

# If not running interactively, don't do anything!

[[ $- != *i* ]] && return

 

# Bash won't get SIGWINCH if another process is in the foreground.

# it regains control.

# Enable history appending instead of overwriting.

만약 명령어가 존재하지 않는다거 하는 에러가 발생한다면 (이것 때문에 쉘이 망가져서 고생 좀 했음...)

아래를 실행해서 업데이트해준다.

 

 

pacman -Sy pkgfile

pkgfile --update

 

 

혹시 문제가 생기거나 한다면 일단 로그아웃 한 후에 다시 접속해서 복사해 두었던 원본 bash.bashrc 파일로 대체하고 다시 해본다.

(적용된 웰컴 메시지 화면 등을 보고 싶다면 로그아웃 후에 다시 접속해야 한다.)

 

팁으로 소스에도 있지만 로그인 시마다 어떤 명언같은 인용구가 랜덤으로 보이게 하고 싶다면, 

 

pacman -S fortune-mod

nano /etc/bash.bashrc

 

# [[ "$PS1" ]] && /usr/bin/fortune (이 부분을 찾아 밑에 넣어준다.)

[[ "$PS1" ]] && echo -e "\e[00;33m$(/usr/bin/fortune)\e[00m"

 

위와 같이 수정 후 로그아웃했다가 다시 로그인하면 브라운 색상으로 인용구가 매번 로그인할 때마다 랜덤으로 나온다.

맨 처음의 화면은 root로 로그인했을 때이고, 다른 사용자 계정으로 로그인하게 되면 웰컴 메시지는 동일하지만 쉘 모양이 root와는 다르다.

하지만 컬러는 적용되어 있어 ls 등을 했을 때 구분이 좀더 쉽게 된다.
