一个优化了一下的自动挂载脚本

[i-do-not-know-my-name]

#!/bin/bash

# 定义挂载目录和用户权限

            fi
            
            # 创建挂载点
            mkdir -p "$MOUNT_POINT"
            
            # 根据文件系统类型设置挂载选项
            case "$FSTYPE" in

done

部分思路根据下面的进行改动

#!/bin/bash

NEW_USB_DEVICE=`ls /dev/ | grep sd..`
FS_TYPE=`blkid|grep /dev/sd..|awk -F'TYPE=' '{print $2}'|awk '{print $1}'|sed  's/"//g'`

echo "Check New Device"
if [ ! -z ${NEW_USB_DEVICE} ]; then
	echo "Check FileSytem Type."
	mkdir /usb-dir >/dev/null 2>&1
	if [[ "${FS_TYPE}" =~ "ntfs" ]]; then
		echo "Mounting NTFS...."
		mount -t ntfs-3g /dev/${NEW_USB_DEVICE} /usb-dir
	else
		echo "Mounting ....."
		mount /dev/${NEW_USB_DEVICE} /usb-dir || mount -t ntfs-3g /dev/${NEW_USB_DEVICE} /usb-dir
	fi
else
	echo "No USB_DEVICE"
	exit 1
fi

MOUNT_INFO=$(df -h | grep "/dev/${NEW_USB_DEVICE}")

# check mounted device
echo "Check Mounted Device"
if [ ! -z "${MOUNT_INFO}" ]; then
	USB_DEVICE=$(ls /dev/| grep sd..)
	if [ ! -z $USB_DEVICE ]; then
		echo "Mount ${USB_DEVICE} Successfully"
		exit 0
	else
		umount /usb-dir
		echo "Device Not Found"
		exit 1
	fi
else
	echo "Mount ${USB_DEVICE} Failed"
	exit 1
fi
