Mac终端人性化配置记录（Bash&item2+oh my zsh）

一、Bash

觉得 item2 + oh my zsh 太麻烦的，可以试试这个简约版的，支持换颜色

配置步骤

.bash_profile和.bashrc的区别

.bash_profile 针对系统所有用户的权限配置（建议安装在这个文件里）
.bashrc 针对某一个用户的权限配置

具体操作

方法一

1. 根目录下点击快捷键shift + command + . 显示隐藏文件

2. 按顺序：访达->前往->前往文件夹->输入~/.bash_profile（必须显示隐藏文件才可以找到，不然就算打开文件所在文件夹也会看不到）

   1. 没有就新建
   2. 双击打开

3. 将下面得代码复制到文件最下面

   function git_branch {
      branch="`git branch 2>/dev/null | grep "^\*" | sed -e "s/^\*\ //"`"
      if [ "${branch}" != "" ];then
   	   if [ "${branch}" = "(no branch)" ];then
   		   branch="(`git rev-parse --short HEAD`...)"
   	   fi
   	   echo " ($branch)"
      fi
   }
   
   export PS1='\u@\h \[\033[01;36m\]\W\[\033[01;34m\]$(git_branch)\[\033[00m\] \$ '
   
   # 30（黑色）、31（红色）、32（绿色）、 33（黄色）、34（蓝色）、35（洋红）、36（青色）、37（白色）
   

4. 保存并退出

5. 终端执行

source ~/.bash_profile

6. 重新打开有仓库的文件夹即可显示

方法二

1. 打开终端 输入

vim ~/.bash_profile

2. 将下面得代码复制到文件最下面

   function git_branch {
      branch="`git branch 2>/dev/null | grep "^\*" | sed -e "s/^\*\ //"`"
      if [ "${branch}" != "" ];then
   	   if [ "${branch}" = "(no branch)" ];then
   		   branch="(`git rev-parse --short HEAD`...)"
   	   fi
   	   echo " ($branch)"
      fi
   }
   
   export PS1='\u@\h \[\033[01;36m\]\W\[\033[01;34m\]$(git_branch)\[\033[00m\] \$ '
   
   # 30（黑色）、31（红色）、32（绿色）、 33（黄色）、34（蓝色）、35（洋红）、36（青色）、37（白色）
   

3. 保存退出，并执行

:wq

source ~/.bash_profile

4. 退出终端界面，重新打开有仓库的文件夹即可显示


遇到的问题

Mac 电脑重启后不生效

因为系统不会自动加载.bashr文件，所以不生效，建议还是配置在.bash_profile文件里面
给文件改名字吧！执行以下命令即可~

mv .bashrc .bash_profile

---

二、item2+oh my zsh

参考文章：https://blog.csdn.net/weixin_31463675/article/details/113081803

背景

系统默认的 shell / zsh / bash使用起来不是很方便。为了用户能更好的和电脑系统进行交流，我们就可以借助 item2 感觉比 Mac 自带的终端好用。
oh my zsh 可配置主题

安装方式

第一步、安装iterm2

这是前提
官网地址：https://iterm2.com/

第二步、安装 oh my zsh

官网地址：https://ohmyz.sh/

我选择的安装：

$sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

其他安装方式

$sh -c "$(wget https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"

安装完成后如下图所示

1. cat /etc/shells 可查看当前所有
2. echo $SHELL 查看当前 shell
3. chsh -s /bin/bash 切换到 bash
4. chsh -s /bin/zsh 切换到 zsh

第三步、安装主题

主题地址：https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
默认配置的主题：robbyrussell
主题列表如下：
路径：~/.oh-my-zsh/theme(访达->前往->前往文件夹)

配置主题位置如下：路径：~/.zshrc(访达->前往->前往文件夹)

第四步、自定义主题

如果配置的主题某些部分不太满意，比如不想显示计算机名，可以拷贝一份出来，修改名字，把${user_host}去掉
按需修改即可

遇到的问题：

用 chsh -s /bin/zsh 命令不生效，提示 chsh: Shell not changed

参考解决文章https://blog.csdn.net/FungLeo/article/details/99448425

mac系统:zsh切换bash提示chsh: no changes made问题
