macOS切换使用zsh并安装ohmyzsh

macOS下切换 zsh 为默认 shell，并安装 oh-my-zsh。

查看系统支持的 Shells#

终端执行 cat /etc/shells 命令可以查看系统支持几种 Shells；

➜  ~ cat /etc/shells
# List of acceptable shells for chpass(1).
# Ftpd will not allow users to connect who are not using
# one of these shells.

/bin/bash
/bin/csh
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh

macOS 预装了 zsh。

查看系统当前使用的 Shell#

终端执行 echo $SHELL 命令可以查看 macOS 系统当前账户使用的默认 Shell：

➜  ~ echo $SHELL
/bin/zsh

切换当前 Shell 为 zsh#

终端执行 chsh -s /bin/zsh 命令可以切换默认 Shell 为更注重用户体验和交互的 zsh。

zsh 配置 profile#

man#

关于 zsh 的加载、启动和运作机制，建议通过 man zsh 手册。

可以阅读 INVOCATION、COMPATIBILITY、RESTRICTED SHELL 相关章节内容。

FILES#

参考 man bash 相关配置 bash-FILES、macOS Env PATH 的讨论。

关于 zsh 的启动加载配置流程机制，可以阅读 man zsh 手册中的 STARTUP/SHUTDOWN FILES、FILES 等章节。

$ man zsh

FILES
       $ZDOTDIR/.zshenv
       $ZDOTDIR/.zprofile
       $ZDOTDIR/.zshrc
       $ZDOTDIR/.zlogin
       $ZDOTDIR/.zlogout
       ${TMPPREFIX}*   (default is /tmp/zsh*)
       /etc/zshenv
       /etc/zprofile
       /etc/zshrc
       /etc/zlogin
       /etc/zlogout    (installation-specific - /etc is the default)

If ZDOTDIR is unset, HOME is used instead. Files listed above as being in /etc may be in another direc- tory, depending on the installation.

未设置环境变量 ZDOTDIR，默认就是 HOME 目录。

系统级配置文件 /etc/zprofile 和 /etc/zshrc 中有内容。

startup#

Customizing the bash shell and its startup files

ohmyzsh/plugins/profiles/ allows you to create separate configuration files for zsh based on your long hostname (including the domain).

安装 OMZ（Oh My ZSH）#

终端执行以下命令可通过 curl（或 wget、httpie）从 github 下载安装流行的 Zsh 配置 Oh My ZSH：

# curl
$ sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
## 或者
$ curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | zsh

# wget
$ sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
## 或者
$ wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

# httpie（有待验证）
$ http --download https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | sh -c
## 或者
http --download https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | zsh

卸载 OMZ#

在终端中运行 uninstall_oh_my_zsh 命令可以卸载 OMZ。

Color Themes#

robbyrussell/oh-my-zsh

https://github.com/robbyrussell/oh-my-zsh/wiki/themes

A list of Themes that don't come bundled with oh-my-zsh

https://github.com/robbyrussell/oh-my-zsh/wiki/External-themes

OMZ 提供了数百种主题，相关文件在 ~/.oh-my-zsh/themes 目录下。

Themes are located in a themes folder and must end with .zsh-theme. The basename of the file is the name of the theme.

    zsh_custom
    └── themes
        └── my_awesome_theme.zsh-theme

Then edit your .zshrc to use that theme.

    ZSH_THEME="my_awesome_theme"

在 .zshrc 里通过 ZSH_THEME 键来设置主题，默认主题是：

    ZSH_THEME=”robbyrussell”

推荐主题#

  • pygmalion (⭐️⭐️⭐️️⭐️⭐️️)
  • bira (⭐️⭐️⭐️️⭐️️)
  • bureau
  • agnoster
  • random
