quota

The command line tool "quota" is used in Unix-like operating systems to manage disk quotas for users.

It allows administrators to set limits on the amount of disk space a user or group can use.

With the "quota" command, administrators can track and control disk usage, preventing users from exceeding their allocated storage space.

The tool provides information on current disk usage, limits, and usage warnings for each user or group.

It allows administrators to generate reports on quota usage for auditing purposes or to identify users who may require additional storage space.

The "quota" command also enables administrators to modify user/group quota settings, such as adjusting limits or resetting usage statistics.

It supports soft quotas and hard quotas. Soft quotas allow users to temporarily exceed their limit without any immediate consequences, whereas hard quotas enforce strict limits.

The command can also be used by regular users to check their own disk quota information and usage status.

The "quota" tool typically works in tandem with the "quotacheck" command, which is used to initialize or update the disk quota system.

Overall, the "quota" command is a critical tool for system administrators to manage and control disk space allocation and usage in Unix-like systems.
