如何在Linux上传递带有感叹号的参数？

./my_script.sh "hello!"

./my_script.sh hello\!

#!/bin/bash
param="$1"
echo "参数是：$param"

./my_script.sh "hello!"

参数是：hello!

#!/bin/bash
options=$(getopt -o "" -l "param:" -n "my_script.sh" -- "$@")
eval set -- "$options"

while true; do
    case "$1" in
        --param)
            param="$2"
            shift 2
            ;;
        --)
            shift
            break
            ;;
        *)
            echo "Unknown option: $1"
            exit 1
            ;;
    esac
done

echo "参数是：$param"

./my_script.sh --param="hello!"

参数是：hello!
