脚本集锦-linux批量挂在磁盘

1.挂载硬盘/取消挂载
fdisk -l
mount /dev/sdb1 /mnt/usb
umount /mnt/usb 或者 umount /dev/sdb1
2.设置硬盘自动挂载
blkid /dev/sdl 查看磁盘的uuid，如果查看不到uuid，就对磁盘进行格式化
格式化命令：mkfs.ext4 /dev/sdl ，/dev/sdl为磁盘名
vi /etc/fstab 添加开机自动
格式如下：

批量挂载磁盘脚本：

#!/bin/sh

#backup /etc/fstab
cp /etc/fstab /etc/fstab.bak
PARTITION_LIST="sdb sdc sdd sde sdf sdg sdh sdi sdj sdk sdl"
cnt=0

for PARTITION in $PARTITION_LIST
do
  cnt=$(($cnt+1));
  UUID=`blkid "/dev/""$PARTITION" | awk '{print $2}' | sed 's/\"//g'`
  echo $UUID

  echo "add $PARTITION to /etc/fstab"
  MOUNTDIR="/mnt/disk"$cnt
  echo "mkdir -p $MOUNTDIR"
  mkdir -p $MOUNTDIR

  echo "appending \"$UUID $MOUNTDIR ext4 defaults 0 0\" to /etc/fstab "
  echo "$UUID $MOUNTDIR ext4 defaults 0 0" >> /etc/fstab
  echo "" 
done

#mount all partitions
mount -a

#show mounted partitions
df -h
