Shell颜色及显示git分支配置

Posted 2020-06-30 fuleying

# Ubuntu终端下命令行颜色配置

## Parses out the branch name from .git/HEAD:

find_git_branch () {

local dir=. head

until [ "$dir" -ef / ]; do

if [ -f "$dir/.git/HEAD" ]; then

head=$(< "$dir/.git/HEAD")

if [[ $head = ref:\ refs/heads/* ]]; then

git_branch="[→ ${head#*/*/}]"

elif [[ $head != ‘‘ ]]; then

git_branch="[→ (detached)]"

else

git_branch="[→ (unknow)]"

fi

return

fi

dir="../$dir"

done

git_branch=‘‘

}

 

# git目录显示当前分支

 

PROMPT_COMMAND="find_git_branch; $PROMPT_COMMAND"

# Here is bash color codes you can use

black=$‘\[\e[1;30m\]‘

red=$‘\[\e[1;31m\]‘

green=$‘\[\e[1;32m\]‘

yellow=$‘\[\e[1;33m\]‘

blue=$‘\[\e[1;34m\]‘

magenta=$‘\[\e[1;35m\]‘

cyan=$‘\[\e[1;36m\]‘

white=$‘\[\e[1;37m\]‘

normal=$‘\[\e[m\]‘

PS1="$magenta\[email protected]$green\h$white:$cyan\w$yellow\$git_branch$white$red\$ $normal"

 

 

用法：把上述代码追加到~/.bashrc文件后面，source ~/.bashrc后打开新终端就可以看到效果了
