一、oh-my-zsh基本介绍
oh-my-zsh：
https://github.com/ohmyzsh/ohmyzsh
https://github.com/ohmyzsh/ohmyzsh
注意：需要先安装zsh命令，才能安装oh-my-zsh，先测试是否安装了zsh
root@server:/opt # zsh --version
zsh 5.8 (x86_64-ubuntu-linux-gnu)
root@server:/opt #
联网安装方式：
curl sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"wget sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"fetch sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
二、离线安装
1、先下载好对应的ohmyzsh的安装包，然后解压缩
root@server:~ ‹master*›# ls -l oh-my-zsh.tar.gz
-rw-r--r-- 1 root root 21923840 Sep 27 16:01 oh-my-zsh.tar.gz

2、安装oh-my-zsh
进入到/root/.oh-my-zsh/tools目录下，先备份install.sh，然后将以下脚本复制
#!/bin/sh
#
# This script should be run via curl:
# sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
# or via wget:
# sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
# or via fetch:
# sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
#
# As an alternative, you can first download the install script and run it afterwards:
# wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
# sh install.sh
#
# You can tweak the install behavior by setting variables when running the script. For
# example, to change the path to the Oh My Zsh repository:
# ZSH=~/.zsh sh install.sh
#
# Respects the following environment variables:
# ZDOTDIR - path to Zsh dotfiles directory (default: unset). See [1][2]
# [1] https://zsh.sourceforge.io/Doc/Release/Parameters.html#index-ZDOTDIR
# [2] https://zsh.sourceforge.io/Doc/Release/Files.html#index-ZDOTDIR_002c-use-of
# ZSH - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
# REPO - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
# REMOTE - full remote URL of the git repo to install (default: GitHub via HTTPS)
# BRANCH - branch to check out immediately after install (default: master)
#
# Other options:
# CHSH - 'no' means the installer will not change the default shell (default: yes)
# RUNZSH - 'no' means the installer will not run zsh after the install (default: yes)
# KEEP_ZSHRC - 'yes' means the installer will not replace an existing .zshrc (default: no)
#
# You can also pass some arguments to the install script to set some these options:
# --skip-chsh: has the same behavior as setting CHSH to 'no'
# --unattended: sets both CHSH and RUNZSH to 'no'
# --keep-zshrc: sets KEEP_ZSHRC to 'yes'
# For example:
# sh install.sh --unattended
# or:
# sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
#
set -e
# Make sure important variables exist if not already defined
#

# POSIX: https://pubs.opengroup.org/onlinepubs/009695299/utilities/id.html
USER=${USER:-$(id -u -n)}
# $HOME is defined at the time of login, but it could be unset. If it is unset,
# a tilde by itself (~) will not be expanded to the current user's home directory.
# POSIX: https://pubs.opengroup.org/onlinepubs/009696899/basedefs/xbd_chap08.html#tag_08_03

#
# 1. Run `sudo` with `-v`. Does the following:
# • with privilege: asks for a password immediately.
# • without privilege: exits with error code 1 and prints the message:
# Sorry, user <username> may not run sudo on <hostname>
#
# 2. Pass `-n` to `sudo` to tell it to not ask for a password. If the
# password is not required, the command will finish with exit code 0.
# If one is required, sudo will exit with error code 1 and print the
# message:
# sudo: a password is required
#
# 3. Check for the words "may not run sudo" in the output to really tell
# whether the user has privileges or not. For that we have to make sure
# to run `sudo` in the default locale (with `LANG=`) so that the message
# stays consistent regardless of the user's locale.

3、执行 ./install.sh，如果是普通用户安装，需要输入root密码才能安装，root用户直接安装则不用
4、安装完成后，配置自动补全功能。vim ~/.zshrc
# 找到 plugins的行，取消注释添加
plugins=(git zsh-autosuggestions)
# zsh模式退出后，需要将输出保留在终端上显示，需要在.zshrc配置中添加（可加可不加）
alias clear=""效果实现第一次输入命令后，第二次输入后会提示，然后直接tab键即可显示整个命令
