dfc
disk usage display with color-coded graphs
TLDR
SYNOPSIS
dfc [-abdfhilmMnosTvwW] [-c when] [-e format] [-p fsname] [-q sortby] [-t fstype] [-u unit]
DESCRIPTION
dfc (disk free color) is an enhanced df command that displays filesystem disk space usage with color-coded bar graphs. It provides a more visual and readable alternative to the traditional df output.The graph bars change color based on usage levels: typically green for low usage, yellow for moderate, and red for high usage. This visual representation makes it easy to quickly identify filesystems approaching capacity.Output can be customized extensively through column selection, sorting, and filtering. The tool supports multiple export formats including CSV, JSON, and HTML for integration with other tools or reporting systems. Filesystem type filtering allows focusing on specific storage types.Configuration options can be set in ~/.config/dfc/dfcrc or /etc/dfc.conf for persistent preferences. Color thresholds and graph characters can be customized in the configuration file.

INSTALL
CAVEATS
Colors require a terminal with color support. Very long mount point names may be truncated in default mode (use -W for full paths). Some virtual filesystems may show unexpected values. Graph width adapts to terminal width.
HISTORY
dfc was created by Robin Hahling as a colorful, user-friendly replacement for the traditional df command. The project focuses on making disk space monitoring more visual and accessible. It's written in C and available in repositories of most major Linux distributions.
