+# quotacheck
+
+> Scan a filesystem for disk usage; create, check and repair quota files.

+- Check all mounted non-NFS filesystems:
+
+`sudo quotacheck --all`

+- Force check even if quotas are enabled:
+
+`sudo quotacheck --force {{mountpoint}}`
+
+- Check quotas on a given filesystem in debug mode:
+
+`sudo quotacheck --debug {{mountpoint}}`
+
+- Report progress as quotacheck progresses:
+
+`sudo quotacheck --verbose {{mountpoint}}`
+
+- Check user quotas:
+
+`sudo quotacheck --user {{user}} {{mountpoint}}`

+
+`sudo quotacheck --group {{group}} {{mountpoint}}`
