macOS上使用zsh

mac自带的 terminal.app 默认使用的是 bash 在使用起来不太舒服,比如:自动大小写转换、跳转目录、git仓库的信息…等等。zsh 能在各方面上对其碾压(后面细说)。再说mac自带的termianl.app虽然用上去还可以,推荐一款软件iTerm.app 来搭配 zsh 使用。这款软件对比terminal软件上,优势在于他的分屏功能、插件和主题(oh-my-zsh更优秀)。

zsh介绍

zsh 是一款功能强大的 shell 软件,它可以兼容 bash,并且提供了很多高效的改进:

首先先看看当前系统中有哪些可以使用的终端:cat /etc/shells 我的电脑中显示如下:

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

zsh安装

Mac系统自带了zsh, 一般不是最新版。使用 homebrew 安装最新版,执行命令:

# 安装zsh
brew install zsh
# 把zsh设为默认
chsh -s /bin/zsh

oh-my-zsh

Oh My Zsh是一个令人愉快的开源社区驱动框架,用于管理您的zsh配置。它捆绑了大量有用的功能,助手,插件,主题以及一些让你惊叹的东西。

安装 oh-my-zsh

# curl/wget 二选一即可
# via curl
$ sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
# via wget
$ sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

Please look over the ~/.zshrc file to select plugins, themes, and options.
p.s. Follow us at https://twitter.com/ohmyzsh.

这样,oh-my-zsh安装成功了,可以打开一个新的命令行标签页查看效果。

设置

配置设置

配置文件在 ~/.zshrc (当前登录用户根目录) 使用vim或其他编辑器打开。

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH=$HOME/.oh-my-zsh

# Set name of the theme to load. Optionally, if you set this to "random"
# it'll load a random theme each time that oh-my-zsh is loaded.
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="robbyrussell"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

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

source $ZSH/oh-my-zsh.sh

# User configuration

# export MANPATH="/usr/local/man:$MANPATH"

# ssh
# export SSH_KEY_PATH="~/.ssh/rsa_id"

# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"
...
# 更多默认设置 ~/.oh-my-zsh/templates/zshrc.zsh-template

主题设置

~/.zshrc 文件中修改 ZSH_THEME="robbyrussell" 默认使用的是 robbyrussell。主题文件放在 ~/.oh-my-zsh/themes 文件夹下面。

themes

主题样式可见: https://github.com/robbyrussell/oh-my-zsh/wiki/Themes

可以网上下载别人的主题文件放入 ~/.oh-my-zsh/themes/hello.zsh-theme。然后启用主题 ZSH_THEME="hello"

插件设置

~/.zshrc 文件中修改 plugins=(git) 默认启用 git。如需启用更多插件,可加入需启用插件的名称,如下: plugins=(rails git textmate ruby lighthouse)

推荐一款插件

zsh-syntax-highlighting(命令语法高亮)

https://github.com/zsh-users/zsh-syntax-highlighting

zsh-syntax-highlighting

目录别名/命令别名(alias)

目录别名

如果我想在命令行中用sublime text打开某个文件:

# sublime text
alias st="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"
# vscode
alias vs="/Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code"

# 打开文件
$ st ./index.js
# 打开文件夹
$ st ./src/

组合命令,可以为git各种命令行操作配置别名。

# 配置sthost
alias sthost="st /etc/hosts"
# 输入sthost即可完成使用sublime打开host文件
$ sthost

# git·命令
alias gl="git clone"
alias ga="git add"
alias gac="ga . && gcm"

目录别名

# 配置目录别名
alias projects="/Users/hello/Documents/Files/projects"
# 不管你在任何目录,cd projects 即可到达
$ cd projects

目录跳转有个更出名的插件:autojump。【强大的一批】

# 安装autojump
$ brew install autojump
# 配置别名
alias j="autojump"

# 使用
$ autojump some-folder
$ j some-folder

卸载 oh-my-zsh

直接在终端中,运行 uninstall_oh_my_zsh 即卸载。

# 卸载
$ uninstall_oh_my_zsh

完事

到这就差不多了,后面有好东西再做更新。
