Ubuntu Manpage: dfc - display file system space usage using graph and colors

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.
