在bash shell脚本中使用getopts来获取长和短的命令行选项

getopts optstring name

#!/bin/bash

while getopts ":vh-:" opt; do
  case $opt in
    -) # 长选项
      case $OPTARG in
        verbose)
          verbose=1
          ;;
        help)
          help=1
          ;;
        *)
          echo "Invalid option: --$OPTARG" >&2
          exit 1
          ;;
      esac
      ;;
    v) # 短选项
      verbose=1
      ;;
    h) # 短选项
      help=1
      ;;
    \?) # 无效选项
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :) # 缺少参数
      echo "Option -$OPTARG requires an argument" >&2
      exit 1
      ;;
  esac
done

shift $((OPTIND-1))

# 处理非选项参数
non_option_args=("$@")

if [ -n "$help" ]; then
  echo "Usage: $0 [-v] [--verbose] [--help]"
  exit 0
fi

if [ -n "$verbose" ]; then
  echo "Verbose mode enabled"
fi

echo "Non-option arguments: ${non_option_args[@]}"
