【ubuntu】切换shell并显示git分支名字

y9kp

显示当前shell

bash 复制代码

echo $SHELL

bash 复制代码

which bash

根据输出，例如 /bin/bash 改变shell：

bash 复制代码

chsh -s /bin/bash

退出
重新登录

加入函数及覆盖PS1

bash 复制代码

# Function to return the current Git branch name
git_branch() {
  # Check if the current directory is in a Git repository
  if git rev-parse --git-dir > /dev/null 2>&1; then
    # Get the current Git branch
    git_branch=$(git symbolic-ref HEAD 2>/dev/null | sed -e 's,.*/\(.*\),\1,')
    # If the branch name is not empty, print it
    if [ ! -z "$git_branch" ]; then
      echo "($git_branch)"
    fi
  fi
}

bash 复制代码

export PS1='\[\e[0;32m\]\u@\h:\[\e[0;36m\]\w\[\e[0;33m\] $(git_branch)\[\e[0m\] $ '
