  16. .Sh DESCRIPTION
  17. .Nm
  18. displays the current usage and mountpoints of mounted filesystems in a space-separated list containing:
  19. Filesystem, Total, Used, Available, Use percentage, Mountpoint.
  20. If
  21. .Ar file
  22. is given
  23. .Nm
  24. filters to the first filesystem containing each
  25. .Ar file .
  26. .Pp
  27. Unlike some implementations the table formatting isn't perfect, you might want to use
  28. .Xr column 1
  29. to get more readable output.
  30. Also padding is disabled when output isn't a TTY so you can more easily use tools like
  31. .Xr cut 1 .
  32. .Sh OPTIONS
  33. .Bl -tag -width Ds
  34. .It Fl a
  35. Display all mounted filesystems, otherwise
  36. .Nm
  37. deduplicates filesystems and skips ones with a blocksize of zero.

  40. .It Fl i
  41. Print inode usage statistics.
  42. .It Fl l
