安装oh-my-zsh后，由于oh-my-zsh有一个git插件（git.plugin.zsh），查看这个文件的命令是
vim ~/.oh-my-zsh/plugins/git/git.plugin.zsh
或者用vscode打开（前提是已经安装了vscode的code命令）
code ~/.oh-my-zsh/plugins/git/git.plugin.zsh
如果嫌麻烦，可以参考，下面是一些常用命令的别名
alias g='git'
alias ga='git add'
alias gaa='git add --all'
alias gra='git remote add'
alias gst='git status'
alias gd='git diff'
alias gcm='git checkout $(git_main_branch)' #即切换到master分支
alias ggpull='git pull origin "$(git_current_branch)"'
alias ggpush='git push origin "$(git_current_branch)"'
alias gpf!='git push --force'
alias gcmsg='git commit -m'
alias gco='git checkout'
alias gm='git merge'
alias grh='git reset'
alias grhh='git reset --hard'
alias gbd='git branch -d'
alias grb='git rebase'
alias grba='git rebase --abort'
alias grbc='git rebase --continue'
