Dfc: Display file system space usage using graph and colors

Question

Hi all,
I wrote a little tool, somewhat similar to df(1) which I named dfc.
To present it, nothing better than a screenshot (because of colors):
And there is a few options available (as of version 3.0.0):
Usage: dfc [OPTIONS(S)] [-c WHEN] [-e FORMAT] [-p FSNAME] [-q SORTBY] [-t FSTYPE]
[-u UNIT]
Available options:
-a print all mounted filesystem
-b do not show the graph bar
-c choose color mode. Read the manpage
for details
-d show used size
-e export to specified format. Read the manpage
for details
-f disable auto-adjust mode (force display)
-h print this message
-i info about inodes
-l only show information about locally mounted
file systems
-m use metric (SI unit)
-n do not print header
-o show mount flags
-p filter by file system name. Read the manpage
for details
-q sort the output. Read the manpage
for details
-s sum the total usage
-t filter by file system type. Read the manpage
for details
-T show filesystem type
-u choose the unit in which
to show the values. Read the manpage
for details
-v print program version
-w use a wider bar
-W wide filename (un truncate)
If you find it interesting, you may install it from the AUR: http://aur.archlinux.org/packages.php?ID=57770
(it is also available on the archlinuxfr repository for those who have it enabled).
For further explanations, there is a manpage or the wiki on the official website.
Here is the official website: http://projects.gw-computing.net/projects/dfc
If you encounter a bug (or several!), it would be nice to inform me. If you wish a new feature to be implemented, you can always ask me by sending me an email (you can find my email address in the manpage or on the official website).
Cheers,
Rolinh

I know I changed the options a lot with 2.1.0 release. I thought it would be better to have -t for filtering and -T for printing the file system type so someone using the original df would not be surprised.
I'm sorry for the inconvenience. There should not be any changes like this one in the future though but I thought it was needed (especially because of the unit options).

Anyway, I now cannot find any way of having colored output showing only some mounts (that aren't all the same type), without modifying the code.
Two suggestions:
1. Introduce a --color option like ls and grep (--color=WHEN, where WHEN is always,never,auto)
Ok, I'll implement this one for 2.2.0 release It'll be more like "-c always", "-c never" and "-c auto" (default) because I do not use long options but I think this would be OK, right?

This was already planned for 2.2.0 release

This is what I would have suggested.

Thanks I'm glad you like it!

This is perfectly fine Moreover, I seem to have some troubles with my e-mail addressee... So it's actually better that you posted your requests here!
