umount multiple mountpoints under same directory
0
My system has a USB, an sd card and an SSD connected. I mounted all the devices USB(/dev/sdb1), SSD(/dev/sda1) and sd card(/dev/mmcblk1p1) under /mnt. Is there any way to unmount all the devices connected at /mnt?
(I can do this by performing grep to lsblk/df/mount output and unmounting individual one but I am looking for another easy solution OR by performing 3 times umount /mnt)
Update 2
Here is output of lsblk(multiple mountpoints)
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232.9G 0 disk
└─sda1 8:1 0 232.9G 0 part /mnt
sdb 8:16 1 14.7G 0 disk
└─sdb1 8:17 1 14.7G 0 part /mnt
and after performing recursive umount
sudo umount --recursive /mnt
lsblk

Better question. Why are you mounting so many partitions to a single point? This sounds like a bad idea....

@j-money, I agree with what you are saying. But, let's say some (bad)programs are mounting these devices under the same tree(/mnt) and In my program, when I want to mount my device at /mnt I want to unmount all the existing ones. Hence I want to know is there any easy way of doing.

Get rid of the program. In this obscure situation, the results are as expected. I do not think there is a way to unmount all mounted points

Try with lazy unmount:
sudo umount -l /mnt

This still doesn't unmount all the /mnt mount points. It just unmounts the last mounted device.
– Rushikesh Gaidhani

Sorry, try "sudo umount -R /mnt" instead.
– Cristian Vrinceanu

This also works same, just unmounted the last mounted device. The other devices are still mounted. Also, I didn't find the '-R' option in the umount manual.
