Shell颜色及显示git分支配置

# 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="$magentau$white@$greenh$white:$cyanw$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
