如何更换linux bash 为zsh

Posted 2023-03-29

Linux/Unix提供了很多种Shell，常用的Shell有这么几种，sh、bash、csh等，想知道你的系统有几种shell，可以通过以下命令查看：

cat /etc/shells

显示如下：

/bin/bash

/bin/csh

/bin/ksh

/bin/sh

/bin/tcsh

/bin/zsh

切换shell的命令

chsh -s /bin/zsh 参考技术A usermod -s /bin/zsh username 参考技术B #!/bin/bash read -p "Please enter your string:" STR

Linux终极shell-zsh的完美配置方案！——oh-my-zsh

Zsh 介绍

Zsh 兼容 Bash，据传说 99% 的 Bash 操作 和 Zsh 是相同的

Zsh 官网：http://www.zsh.org/

先看下你的 Linux支持哪些 shell：cat /etc/shells，正常结果应该是这样的：

/bin/sh

/bin/bash

/sbin/nologin

/bin/dash

/bin/tcsh

/bin/csh

默认 CentOS / Ubuntu / Mac 系统用的是 Bash，倒也不是说 Bash 不好，而是说我们有更好的选择。

Zsh 安装

CentOS 安装：sudo yum install -y zsh

Ubuntu 安装：sudo apt-get install -y zsh

在检查下系统的 shell：cat /etc/shells，你会发现多了一个：/bin/zsh

使用 Zsh 扩展集合：oh-my-zsh

oh-my-zsh 帮我们整理了一些常用的 Zsh 扩展功能和主题：https://github.com/robbyrussell/oh-my-zsh

我们无需自己去捣搞 Zsh，直接用 oh-my-zsh 就足够了，如果你想继续深造的话那再去弄。

先安装 git：sudo yum install -y git

安装 oh-my-zsh（这个过程可能会有点慢，或者需要重试几次）：wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O - | sh

整个过程效果如下图：

在以 root 用户为前提下，oh-my-zsh 的安装目录：/root/.oh-my-zsh

在以 root 用户为前提下，Zsh 的配置文件位置：/root/.zshrc

为 root 用户设置 zsh 为系统默认 shell：chsh -s /bin/zsh root

如果你要重新恢复到 bash：chsh -s /bin/bash root

现在你关掉终端或是重新连上 shell，现在开头是一个箭头了，如下图：

现在zsh和oh-my-zsh都安装好了，现在重点讲下zsh的配置!

创建~/.zshrc配置文件，先给看下我的配置，可以凭自己喜好更改：

# 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/amoscykl/.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

# zhs的主题

ZSH_THEME="ys"

# Set list of themes to load

# Setting this variable when ZSH_THEME=random

# cause zsh load theme from this variable instead of

# looking in ~/.oh-my-zsh/themes/

# An empty array have no effect

# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

 

# Uncomment the following line to use case-sensitive completion.

# CASE_SENSITIVE="true"

 

# Uncomment the following line to use hyphen-insensitive completion. Case

# sensitive completion must be off. _ and - will be interchangeable.

# HYPHEN_INSENSITIVE="true"

 

# Uncomment the following line to disable bi-weekly auto-update checks.

# DISABLE_AUTO_UPDATE="true"

 

# Uncomment the following line to change how often to auto-update (in days).

# export UPDATE_ZSH_DAYS=13

 

# Uncomment the following line to disable colors in ls.

# DISABLE_LS_COLORS="true"

 

# Uncomment the following line to disable auto-setting terminal title.

# DISABLE_AUTO_TITLE="true"

 

# Uncomment the following line to enable command auto-correction.

# ENABLE_CORRECTION="true"

 

# Uncomment the following line to display red dots whilst waiting for completion.

# COMPLETION_WAITING_DOTS="true"

 

# Uncomment the following line if you want to disable marking untracked files

# under VCS as dirty. This makes repository status check for large repositories

# much, much faster.

# DISABLE_UNTRACKED_FILES_DIRTY="true"

 

# Uncomment the following line if you want to change the command execution time

# stamp shown in the history command output.

# The optional three formats: "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"

# HIST_STAMPS="mm/dd/yyyy"

 

# 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 z zsh-autosuggestions extract web-search zsh-syntax-highlighting 

)

 

source $ZSH/oh-my-zsh.sh

 

# User configuration

 

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

 

# You may need to manually set your language environment

# export LANG=en_US.UTF-8

 

# Preferred editor for local and remote sessions

# if [[ -n $SSH_CONNECTION ]]; then

#   export EDITOR=‘vim‘

# else

#   export EDITOR=‘mvim‘

# fi

 

# Compilation flags

# export ARCHFLAGS="-arch x86_64"

 

# ssh

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

 

# Set personal aliases, overriding those provided by oh-my-zsh libs,

# plugins, and themes. Aliases can be placed here, though oh-my-zsh

# users are encouraged to define aliases within the ZSH_CUSTOM folder.

# For a full list of active aliases, run `alias`.

#

# Example aliases

# alias zshconfig="mate ~/.zshrc"

# alias ohmyzsh="mate ~/.oh-my-zsh"

#

#自动补全插件

source ~/.oh-my-zsh/plugins/incr/incr.zsh

 

# 自动更新的时间间隔，单位是天，这里设置 30 天更新一次

export UPDATE_ZSH_DAYS=1
