一个mount U盘的脚本

一个mount U盘的脚本

由于工作需要，经常在redhat 9下使用U盘，redhat 9下U盘无法自动mount，所以，写了一个脚本来简化操作。
通常情况下，U盘设备应该是 /dev/sda1， 但是，有时候先后使用两个不同的U盘时，后面插入的一个是 /dev/sdb1，所以，使用了 fdisk -l | grep sd[b-z]1 | awk '{print $1}'  来取得它的设备名。代码只能mount 一个U盘，因为我基本上不会同时插入两个U盘，有这一需求的朋友可以自己修改。

#! /bin/sh
#
# Mount/Unmount a USB disk.
#
# Mount:
#    We try to mount /dev/sda1 first, if failed, search /dev/sdb1, /dev/sdc1 ...,
#    and try to mount the 1st one we found.
#

MOUNT_DIR=/mnt/usb
MOUNT_DEV=/dev/sda1

mount | grep $MOUNT_DIR

if [ "$?" = "0" ]
then

    # Kill all process locked the USB disk
    fuser -m -v -k -i $MOUNT_DIR

    umount $MOUNT_DIR
    if [ "$?" = "0" ]
    then
        echo USB disk at $MOUNT_DIR has been unmounted
    else
        echo Can not unmount $MOUNT_DIR
    fi

else
    mount -t vfat /dev/sda1 $MOUNT_DIR -o codepage=936,iocharset=cp936 2>/dev/null

    if [ "$?" = "0" ]
    then
        echo USB disk $MOUNT_DEV has been mounted at $MOUNT_DIR
    else

        #
        # Search all USB disk devices, and mount the first one
        #
        for MOUNT_DEV in $(fdisk -l | grep sd[b-z]1 | awk '{print $1}')
        do
            if [ "$?" = "0" ]
            then
                mount -t vfat $MOUNT_DEV $MOUNT_DIR -o codepage=936,iocharset=cp936 2>/dev/null
                if [ "$?" = "0" ]
                then
                    echo USB disk $MOUNT_DEV has been mounted at $MOUNT_DIR
                    exit 0
                fi
            fi
        done

        echo Can not mount $MOUNT_DEV to $MOUNT_DIR

    fi

fi

exit 0

注意：如果U盘是在Windows下格式化的，则上面可能没有分区，所以，U盘设备是/dev/sda (而不是/dev/sda1)，则上面的脚本不合适，需要修改。
