1.alias

以安装了zsh为例，其中通过在 ~/.zshrc 追加 alias，减少常用指令的时间时间开销 ，"shift + g"跳到文件最后一行

#git
alias ga="git add"
alias gl="git log"
alias gt="git status"
alias gc="git commit"
alias gco="git checkout"
alias gcb="git checkout -b"
alias gp="git push"
alias gpl="git pull"
alias gd="git diff"
alias gb="git branch"
alias gst="git status"
alias gg="git add . && git commit -m 'feat: auto commit' && git push"
2.nodejs 
alias n10="nvm use 10.22.0"
alias dev="npm run dev"
alias debug="npm run debug"
3.common 
alias czsh="vi ~/.zshrc"
alias szsh="source ~/.zshrc"

alias la='ls -a'
alias lla='ls -al'

alias showip="ifconfig | grep inet | grep -v inet6"
alias mkdir="mkdir -p"

alias nginx='/usr/local/nginx/sbin/nginx'

alias tree="find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g'"
alias t="trans"

alias jdk6="export JAVA_HOME=$JAVA_6_HOME" #编辑一个命令jdk6，输入则转至jdk1.6

alias jdk8="export JAVA_HOME=$JAVA_8_HOME" #编辑一个命令jdk8，输入则转至jdk1.8
export JAVA_HOME=`/usr/libexec/java_home`  #最后安装的版本，这样当自动更新时，始终指向最新版本
