Silently ensures that a FS is mounted on the given mount point (checks if it's OK, otherwise unmount, create dir and mount)

(mountpoint -q "/media/mpdr1" && df /media/mpdr1/* > /dev/null 2>&1) || ((sudo umount "/media/mpdr1" > /dev/null 2>&1 || true) && (sudo mkdir "/media/mpdr1" > /dev/null 2>&1 || true) && sudo mount "/dev/sdd1" "/media/mpdr1")
In my example, the mount point is /media/mpdr1 and the FS is /dev/sdd1 /mountpoint-path = /media/mpdr1 filesystem=/dev/sdd1 Why this command ? Well, in fact, with some external devices I used to face some issues : during data transfer from the device to the internal drive, some errors occurred and the device was unmounted and remounted again in a different folder. In such situations, the command mountpoint gave a positive result even if the FS wasn't properly mounted, that's why I added the df part. And if the device is not properly mounted, the command tries to unmount, to create the folder (if it exists already it will also work) and finally mount the FS on the given mount point.
Sample Output
alex@alex-G73Sw:~$ (mountpoint -q "/media/mpdr1" && df /media/mpdr1/* > /dev/null 2>&1) || ((sudo umount "/media/mpdr1" > /dev/null 2>&1 || true) && (sudo mkdir "/media/mpdr1" > /dev/null 2>&1 || true) && sudo mount "/dev/sdd1" "/media/mpdr1")
alex@alex-G73Sw:~$ 

What Others Think

When I unplug my USB drive, sometimes mountpoint still reports the path as a mount point ! In this case, your command was useful, thanks.

works well, but why " || true " ?

@gentroot: Because bracket block needs end with true to exec the following mount command, as is joined with &&.

One thing I would like to say is that car insurance canceling is a feared experience so if you’re doing the suitable things as being a driver you won’t get one. A number of people do receive the notice that they’ve been officially dropped by their insurance company they then have to struggle to get supplemental insurance after a cancellation. Cheap auto insurance rates usually are hard to get from cancellation. Knowing the main reasons for auto insurance canceling can help people prevent getting rid of in one of the most essential privileges readily available. Thanks for the ideas shared through your blog. situs judi online24jam terpercaya 2022
