getopts; complete 用于获取短参数和提供补齐。少数人用while shift/read;case 来解析
还有一个select in ; do，和py2 print 是异曲同工之败笔，请
->展示zenity的所有功能，并生成一个简短的MC风格的文字冒险

#!/bin/bash

while getopts ":n:s:err" opt; do #?未知 :空
  case $opt in
    n) n=$OPTARG ;;
    s) s=$OPTARG ;;
    err) isErr=1 ;;
  esac
done
printf "%d*%s E%d\n" $n $s $isErr

ycm() {
  local cur prev words cword
  _init_completion -n = || return

  case $prev in
    -s) COMPREPLY=($(compgen -e -- "${cur}")); return 0 ;;
    *) COMPREPLY=($(compgen -W "-n -s -err" -- "${cur}"));;
  esac
}
complete -F ycm $0

使用 chmod +x a.sh; . a.sh 注册后./执行 即可Tab补齐

这样，您可以快速阅读调用帮助： for c in python node ruby lua "kotlin -h" "git init" pip sed awk grep nano bash;do ? $c; done
或者，下载存储库及文件 uc cd https://github.com/hyprwm/Hyprland?d1

uc ls https://mirrors.ustc.edu.cn/xbmc/releases/android/x86/kodi-20.2-Nexus-x86.apk

切换文件夹 ? a b/{1,2} c/ (在jupyter)安装依赖 ? import srt
🎁 允许用py调用系统上的.so 库如 pkgcSel caca alpm
