zsh: command not found: brew 报错解诀办法

命令行执行：

  1. /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

安装wget

  1. brew install wget

验证——安装redis试试

  1. wget https://download.redis.io/releases/redis-6.0.8.tar.g

替换bash的方式：chsh -s /bin/zsh。关闭终端，再次打开即为zsh。

zsh 下 git 别名（alias） 和 oh-my-zsh git 插件

学习 git 的过程中，想给一些 git 命令设置一些别名，这样也可以提高一下效率。
因为用的是 zsh ，就在 ~/.zshrc

  1. 1. alias gst='git status'
  2. 2. alias gcm='git commit -m '
  3. 3. alias gps='git push'
  4. 4. alias glg='git log --graph'

结果在执行 gcm 的时候，运行不正确。用 alias gcm 查看该别名设置：

1. ➜  ~ alias gcm
2. gcm='git checkout master'

原来配置成了其他命令。
但是奇怪的是，在 .zshrc 文件中并没有找到相关配置。经过仔细阅读，最终发现了下面这条语句：

1. # Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
2. # Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
3. # Example format: plugins=(rails git textmate ruby lighthouse)
4. # Add wisely, as too many plugins slow down shell startup.
5. plugins=(git)

原来我的 zsh 安装了 oh-my-zsh，不知道是我自己安装还是默认自带了一个 git 插件，那我们按照注释说明，到那个插件下看一下吧。

1. cd ~/.oh-my-zsh/plugins/git
2. ls
3. README.md      git.plugin.zsh

可以看到一个 git.plugin.zsh 文件，vi 打开，看到一些 functions 和 N 多的 alias。
具体文件内容我就懒得贴出来了，如果你有兴趣，终端下执行一下 alias 就列出所有可用别名，比看那个 git.plugin.zsh 文件更清楚明了 。

即便你没有安装 zsh 和 oh-my-zsh，个人觉得这些别名的设置还是可以借鉴一下的。

最后说一句：不同的 shell ，alias 配置文件是不同的，你执行 alias 显示的也会不同。比如 Mac 默认的 bash，其配置文件可能是 /etc/bashrc、~/bashprofile 或者 /etc/profile。而 zsh 默认是 ~/.zshrc. 另外，用命令 alias 设置的别名为临时别名，shell 重启后就会失效。如: alias la="ls -al" 。如果你重启了还有效，那可能能在上述配置文件中找到。^^

open 命令

参数-a，指定打开文档的app：

 ` open -a TextEdit settings.xml`

参数-e，使用“文本编辑器”app打开：

 ` open -e settings.xml`

参数-t，使用系统默认的编辑器打开：

 ` open -t settings.xml`
