Quickly create formatted disks and detailed operation steps for shell scripts

This article introduces you how to use shell scripts to implement partition formatting and mount a disk. The specific content is as follows:

Check the current disk partition status

Check the current partition status of a disk, use the command: fdisk -l

fdisk -l
//View disk informationlsblk

Let the hard disk enter partition mode

fdisk /dev/sdb

Order(enter m Get help)： m //Print options menu
Add a new partition:
Order(enter m Get help)：n //Add a partition
Select a partition type：
Select (default p): e 
//Enter e indicates the creation of an extended partition
Number of partitions:
Partition number (1-4，default 1)：1

Set up sectors:
Start Sectors (2048-83886079，default为 2048)：Enter 
Last Sectors, +Sectors or +size{K,M,G} (2048-83886079，default为 83886079)：Enter

save
Order(enter m Get help)：w //save退出

Format operation, you can mount it and use it after completion

mkfs -t ext3 /dev/sdb

//mount the file system and mirror the ISO to the specified folder.//temporary:mount /dev/cdrom（Source File） /mnt（Source load point）
//permanent:vi /etc/fstab
dev/sdb /mnt iso9660 default 0 0

Create, format, and mount newly added disk scripts through administrator selection

Note: Create the disk first

#! /bin/bash
#Use shell script to implement partition format mount of a diskPS3="Prompt to select the disk to create:"
select W in `ls /dev/sd*|grep -o 'sd[b-z]'|uniq` quit
do
  case $W in
  sda)
   fdisk -l /dev/sda
   break;;
  sd[b-z])
    echo "n
      p

      w" | fdisk /dev/$W
   -i size=512 /dev/${W}"1" &amp;&gt;/dev/null
  mkdir -p /data/${W}"1" &amp;&gt;/dev/null
  echo -e "/dev/${W}"1" /data/${W}"1" xfs defaults 0 0\n" &gt;&gt; /etc/fstab
  mount -a &amp;&gt;/dev/null
  break;;
  quit)
  break;;
  *)
  echo "The wrong disk，Please check again";;
  esac
done

Automatically create, format and mount newly added disk scripts

#!/bin/bash
useshellScript implementation partition format mounts a disk

for V in $(ls /dev/sd[b-z])
do
 echo -e "n\np\n\n\n\nw\n" |fdisk $V
  -i size=512 ${V}1 &amp;&gt;/dev/null
 sleep 1
 M=$(echo "$V" |awk -F "/" '{print $3}')
 mkdir -p /data/${M}1 &amp;&gt;/dev/null
 echo -e "${V}1 /data/${M}1 xfs defaults 0 0\n" &gt;&gt;/etc/fstab
 mount -a &amp;&gt;/dev/null
done

Cancel the mount

 umount /dev/sdb

Delete the partition

Note: Enter the disk session

fdisk /dev/sdb 

//Enter partition modem d 1 Operation in turn
