.bashrc의 PS1이 다른 곳에서 덮어쓰기되었습니다.

색상 및 Git 저장소 정보를 포함하여 Red Hat Enterprise Linux 6 시스템에서 사용자 정의 PS1 라인을 사용하려고 합니다. Ubuntu 또는 Mint를 실행하는 다른 시스템에서 성공적으로 작동하는 사전 정의된 버전이 있습니다.

광산에서는 .bashrc맨 아래에 다음 섹션을 추가했습니다.

# Colors
Black='\e[0;30m'        # Black
Red='\e[0;31m'          # Red
...
NC="\e[m"               # Color Reset

# show git branch
parse_git_branch() {
  # git branch 2> /dev/null | sed -e '/^\[^*\]/d' -e 's/* \(.*\)/|\1/'
  git rev-parse --abbrev-ref HEAD 2> /dev/null | sed 's/^/|/g'
}
PS1="\[$Green\]\u@\h \[$BBlack\]\w\[$Yellow\]\$(parse_git_branch)\[$NC\] $ "

그러나 터미널을 열면 여전히 기본 PS1 라인이 표시됩니다. 인쇄물 .echo $PS1​ \[\033]0;\u@\h: \w\007\]\u@\h:\w>분명히 이 변수는 어딘가에서 재정의되었습니다. 하지만 어디서, 어떻게 찾을 수 있나요?

그런데 .bashrc실행은 확실합니다. 라인을 추가 echo "hello"하고 터미널을 열었을 때 결과를 확인하여 이를 확인했습니다 .

고쳐 쓰다

실행하면 bash -x많은 출력이 인쇄됩니다.

+ On_White='\e[47m'
+ NC='\e[m'
+ PS1='\[\e[0;32m\]\u@\h \[\e[1;30m\]\w\[\e[0;33m\]$(parse_git_branch)\[\e[m\] $ '
++ PS1='\[\033]0;\u@\h: \w\007\]\u@\h:\w> '
