openwrt hotplug mount script enhanced

最近在rg100a上折腾openwrt…
参考dev上的信息,强化了下自动mount的脚本
顺便又学习了下shell script,嗯,玩中学,学中玩^^

/etc/hotplug.d/block/10-mount

#!/bin/sh

blkdev=`dirname $DEVPATH`
if [ `basename $blkdev` != "block" ]; then
 
    device=`basename $DEVPATH`
    case "$ACTION" in
        add)
                mkdir -p /mnt/$device
                # vfat & ntfs-3g check
                if  [ `which fdisk` ]; then
                        isntfs=`fdisk -l | grep $device | grep NTFS`
                        isvfat=`fdisk -l | grep $device | grep FAT`
                        isfuse=`lsmod | grep fuse`
                        isntfs3g=`which ntfs-3g`
                else
                        isntfs=""
                        isvfat=""
                fi 
 
                # mount with ntfs-3g if possible, else with default mount
                if [ "$isntfs" -a "$isfuse" -a "$isntfs3g" ]; then
                        ntfs-3g -o nls=utf8 /dev/$device /mnt/$device
                elif [ "$isvfat" ]; then
                        mount -o iocharset=utf8 /dev/$device /mnt/$device
                else
                        mount /dev/$device /mnt/$device
                fi
                ;;
        remove)
                umount /dev/$device
                ;;
    esac
