Copy quota settings

Set quota on all filesystems
sudo setquota -a -u [username] [block-soft] [block-hard] [inode-soft] [inode-hard]
Set grace times
sudo setquota -t -u [block-grace] [inode-grace] [/path/to/filesystem]

说明
setquota is a command-line quota editor that sets disk quotas for users, groups, or projects on a filesystem. Unlike the interactive edquota command, setquota allows quota configuration in a single command, making it suitable for scripts and automation. Quotas can limit both disk space usage (blocks) and number of files (inodes). Each limit has a soft limit (can be exceeded temporarily) and a hard limit (absolute maximum). When a soft limit is exceeded, the grace period begins, after which the soft limit becomes a hard limit. Block limits are typically specified in kilobytes, though this may vary by quota format. If a numeric value is given instead of a username, it is treated as a UID/GID/project ID.
