NAME
       dfc - display file system space usage using graph and colors

SYNOPSIS
       dfc [OPTION(S)] [-c WHEN] [-u UNIT] [-t FILESYSTEM]

DESCRIPTION
       dfc  is a tool similar to df(1) except that it is able to show a graph
       along with the data and is able to use color (color  mode  is  "color-
       auto" by default but you can change this with "-c" option).

       The  available  size correspond to the space available to a user point
       of view and not from root's perspective (ie: use f_bavail  instead  of
       f_bfree).   In  the  same  idea, used space is computed simply by sub‐
       stracting the available space from the total size.

       Without any argument, size is displayed in human readable format.   Be
       aware  that  when  using     human-readable     format,  there might be some
       rounding when computing the size. If you want maximum  precision,  use
       the "-u" option and choose the unit.

       dfc(1)  also  has a built in feature that makes the output auto adjust
       based on terminal width. If you want to override     this  behavior,  use
       the "-f" option.

OPTIONS
       -a     Show information about all file systems found in the mtab file.

       -b     Do not show the graph bar.

       -c [WHEN]
          Choose  color  mode  where  WHEN    is  one of the following sub-
          option:

          "always":         Color will always be used, no matter what stdout
          is.

          "auto":        This is default when "-c" is not activated. Color
          is used only if "stdout" is a  terminal.    For  instance,    color
          will  be    disabled  with    this option if you pipe the output of
          dfc(1) into another command.

          "never":        Color will never be used.

       -f     Override auto-adjust behavior by forcing information to be dis‐
          played.    You  probably do not want to activate this option but
          choice is yours.    This option can be useful  if  you  pipe  the
          output of dfc(1) though.

       -h     Show a short help text.

       -i     Show information about inodes.

       -m     Use  SI units (metric) (ie: size is computed using powers of 10
          instead of powers of 2).

       -n     Do not print header.

       -o     Show mount options.

       -s     Sum the total usage.

       -t [FILESYSTEM]
          Allows you to perform filtering on file system type. FILESYSTEM
          could  take  any known file system value. For instance, "ext4",
          "ufs", "tmpfs", "reiserfs", etc.

          Multiple selection on file system is  also  possible.  In     this
          case,  FILESYSTEM needs to be comma separated (without spaces).
          For instance, if you want to filter  "ext4"  and    "tmpfs",  you
          would use the following:

           dfc -t ext4,tmpfs

          You  can also use negative matching to filter the output. To do
          so, you just need to prepend a "-" to FILESYSTEM. In  the     fol‐
          lowing example, dfc(1) will display all file system type except
          those mentionned:

           dfc -t -rootfs,tmpfs

       -T     Show filesystem type.

       -u [UNIT]
          Show size using unit specified. UNIT can take one of  the     fol‐
          lowing value:

          "h":    Human readable (default when not using "-u" option).

          "b":    Show bytes.

          "k":    Show size using Kio.

          "m":    Show size using Mio.

          "g":    Show size using Gio.

          "t":    Show size using Tio.

          "p":    Show size using Pio.

          "e":    Show size using Eio.

          "z":    Show size using Zio.

          "y":    Show size using Yio.

          NOTE: When using "-u" option along with "-m" option, those sub‐
          options are replaced by their SI counterparts.

       -v     Print dfc version and exit.

       -w     Use a wider bar.
