ssh终端显示git分支名：
1 #set git branch 2 green=$'e[0;32m' 3 magenta=$'e[0;36m' 4 normal_colours=$'e[m' 5 6 function find_git_branch { 7 local dir=. head 8 until [ "$dir" -ef / ]; do 9 if [ -f "$dir/.git/HEAD" ]; then 10 head=$(< "$dir/.git/HEAD") 11 if [[ $head == ref: refs/heads/* ]]; then 12 git_branch="(${head#*/*/})#" 13 elif [[ $head != '' ]]; then 14 git_branch='(detached)' 15 else 16 git_branch='(unknown)' 17 fi 18 return 19 fi 20 dir="../$dir" 21 done 22 git_branch='#' 23 } 24 25 PROMPT_COMMAND="find_git_branch; $PROMPT_COMMAND" 26 PS1="[$green][u@h W][$magenta]$git_branch[$green]\[$normal_colours] "
将上面这段，追加 /etc/profile 或 ~/.bash_profie 或 ~/.bashrc 任何一个的最后，然后source /etc/profile (或source ~/.bash_profile 或 source ~/.bashrc)，让其生效即可。
