linux CentOS 安装oh my Zsh
linux 默认bash shell是这样
想变的酷一点，类似这样：
zsh
先了解下什么是zsh？
https://wiki.archlinux.org/index.php/Zsh_(%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87)
安装oh my Zsh
官网：https://ohmyz.sh/ 提供两种安装方式
//via curlsh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"//via wgetsh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

继续执行安装oh my Zsh

安装成功
更改默认shell
查看系统默认shell,$SHELL是大写
echo $SHELL
查看系统shell列表
cat /etc/shells
更改系统shell为zsh
chsh -s /usr/bin/zsh
更换主题
oh my Zsh默认主题是这样子的
修改vi ~/.zshrc的ZSH_THEME="robbyrussell"为ZSH_THEME="agnoster"
➜ / vi ~/.zshrc# 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="/root/.oh-my-zsh"# Set name of the theme to load --- if set to "random", it will# load a random theme each time oh-my-zsh is loaded, in which case,# to know which specific one was loaded, run: echo $RANDOM_THEME# See https://github.com/robbyrussell/oh-my-zsh/wiki/ThemesZSH_THEME="robbyrussell"# Set list of themes to pick from when loading at random# Setting this variable when ZSH_THEME=random will cause zsh to load# a theme from this variable instead of looking in ~/.oh-my-zsh/themes/# If set to an empty array, this variable will 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.

退出终端（如xshell)，重新登录，就变成这样了
环境变量问题
更换shell后，mongo环境变量用不了，需要重新配置mongo环境变量
vi ~/.bash_profile# 加入mongo配置export MONGODB_HOME=/usr/local/mongodb-4.0.2/binexport PATH=$MONGODB_HOME:$PATH
使用source ~/.bash_profile使环境变量生效

命令从指定点开始将 File 参数指定的文件写到标准输出。如果没有指定文件，那么会使用标准输入。Number 变量指定将多少单元写到标准输出。Number 变量的值可以是正的或负的整数。如果值的前面有 +（加号），从文件开头指定的单元数开始将文件写到标准输出。如果值的前面有 -（减号），那么从文件末尾指定的单元数开始将文件写到标准输出。如果值前面没有 +（加号）或 -（减号），那么从文件末尾指定的单元号开始读取文件
