28. You cannot unmount a filesystem that you had previously mounted to the /mnt directory. What command can show you which users are still using the /mnt directory?

Answer 1

24) The ‘df‘ command stands for “disk filesystem“, it is used to get a full summary of available and used disk space usage of the file system on Linux system.

26) Edquota command is used to edit the quotas for a user or group. This is just an editor, from where you can change the quota values.

27) To repair a ReiserFS filesystem you need to run reiserfsck command, which is a checking tool for the ReiserFS filesystem (just like fsck command for ext2/ext3 file system).Reiserfsck searches for a Reiserfs filesystem on a device, replays any necessary transactions, and either checks or repairs the file system.

28) Use umount command to unmount any mounted filesystem on your system. Run umount command with disk name or mount point name to unmount currently mounted disk.
