findmnt – find all the mounts and their source

If you are looking for the source of a mount and the various options used in the mount, then the quickest way to get that is ::

findmnt

By default, with no parameters, it lists all the mounts in a tree like view and all the options used to mount the path. It also lists the source of the mount.

By default again, it uses some capabilities of the terminal to show the tree which you can disable with the option “-a”.

You can check the man page for more information on this command, it has some pretty good examples as well.

And just in case, you are unable to find the package (util-linux) containing the command:

sudo yum install util-linux

Find directory/file with inode number

Couple of days back, I was getting the following error:

Directory inode 2362521 has an unallocated block #245823.  Allocate?

And this continued for hours together and I was in a hurry. Did not really care about the error and all I wanted was to get rid of the error but for that I needed to get to the file/directory with inode number  mentioned in the error and finally “find” command came to rescue:

find . -inum

This gave me the directory with the inode number in the error and all I had to do was delete that directory 🙂
