NAME

       dfc - display file system space usage using graph and colors

SYNOPSIS

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

DESCRIPTION

       dfc(1)  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 substracting 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 displayed.  You probably
              do not want to activate this option but choice is yours.  This option may 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 following 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 following 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 suboptions are  replaced
              by their SI counterparts.

       -v     Print dfc(1) version and exit.

       -w     Use a wider bar.

       -W     Wide path name (avoid truncation of file name). May require a larger display.
