NAME       xfs_quota - manage use of quota on XFS filesystems
SYNOPSIS       xfs_quota [ -x ] [ -p prog ] [ -c cmd ] ... [ -d project ] ... [ path ... ]       xfs_quota -V
DESCRIPTION       xfs_quota is a utility for reporting and editing various aspects of filesystem quota.
       The options to xfs_quota are:
       -c cmd    xfs_quota commands may be run interactively (the default) or as arguments on the command line. Multiple -c arguments may                 be given.  The commands are run in the sequence given, then the program exits.
       -p prog   Set the program name for prompts and some error messages, the default value is xfs_quota.
       -x        Enable expert mode.  All of the administrative commands (see the ADMINISTRATOR COMMANDS section below) which allow modi‐                 fications to the quota system are available only in expert mode.
       -d project                 Project  names  or  numeric  identifiers may be specified with this option, which restricts the output of the individual                 xfs_quota commands to the set of projects specified. Multiple -d arguments may be given.
       -V        Prints the version number and exits
