git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh}/plugins/zsh-autosuggestions

git clone https://github.com/zsh-users/zsh-history-substring-search ${ZSH_CUSTOM:-~/.oh-my-zsh}/plugins/zsh-autosuggestions

chsh -s /bin/zsh root
chsh -s /bin/zsh

在.bashrc中添加：

个性化文字

precmd(){
    echo -e "                          ~~哟呵，又在写bug o_o#"
}

setopt HIST_FIND_NO_DUPS
setopt HIST_IGNORE_ALL_DUPS
setopt nosharehistory
setopt INC_APPEND_HISTORY
setopt incappendhistorytime
export HISTFILESIZE=1000000000
export HISTSIZE=1000000000
export HISTTIMEFORMAT="[%F %T] "
export HISTFILE=~/.zsh_history
