Device Management- Mounting and Unmounting using Shell Scripting

Q:- Write a shell script to mount and unmount devices using shell scripting. Also display the list of devices currently available to the system.

 

 Code

#!/bin/bash
function mntdev
{
 echo "Currently mounted devices are: "
 lsblk
}
function pcidev
{
 echo "Following are the PCI devices: "
 lspci
}
function usbdev
{
 echo "Following are the USB devices"
 lsusb
}
function mountfunc
{
 echo "Enter the name of the device to be mounted "
 read devicename
 echo "Enter the directory present in Home for the destination"
 read directoryname
 mkdir $directoryname
 mount /dev/$devicename $directoryname
 echo "The device is mounted"
 cd $dirname
 ls
 cd ..
}
function unmountfunc
{
 lsblk
 echo "Enter the path for unmounting"
 read path
 umount -v $path
 echo "The device has been unmounted"
} 
while [ true ]
do
echo "Please Enter a Choice"
echo "0]List the currently mounted devices"
echo "1]List PCI devices"
echo "2]List connected USB devices"
echo "3]Mount a device"
echo "4]Unmount a device"
echo "5]Exit"
read ch



case $ch in
0)mntdev ;;
1)pcidev ;;
2)usbdev ;;
3)mountfunc ;;
4)unmountfunc ;;
5)
echo "Terminating script" 
break ;;
*)echo "Invalid choice entered" ;;
esac
done
