Linux disk quota Management Picture and text case

Disk quota is the storage limit of the specified disk in the computer, that is, the administrator can impose a quota on the disk space that users can use, and each user can only use the disk space within the maximum quota range. This can prevent other users from working properly or even affecting the operation of the system due to the excessive use of disk space by one user. This feature is very important in server management, but it doesn't make much sense for stand-alone users.
