dfc (disk free color) displays filesystem disk space usage with color output. Enhanced version of df with better formatting and visual indicators.

Basic Usage

  • dfc - Show all filesystems
  • dfc / - Show specific mount point
  • dfc -h - Human-readable sizes
  • dfc -T - Show filesystem types

Options

  • -h - Human-readable sizes (KB, MB, GB)
  • -T - Show filesystem type
  • -t type - Show only specific filesystem type
  • -x type - Exclude filesystem type
  • -a - Show all filesystems including pseudo
  • -i - Show inode information
  • -l - Local filesystems only
  • -n - No color output

Common Examples

Human Readable

dfc -h

Show disk usage in readable format.

With Types

dfc -T

Include filesystem types.

Specific Mount

dfc -h /

Check root filesystem.

Local Only

dfc -l

Show only local filesystems.

Inode Usage

dfc -i

Display inode information.

Tips

  • Use -h for human-readable output
  • Use -T to see filesystem types
  • Color coding helps identify usage levels
  • Use -l to filter out network mounts
  • Essential for disk space monitoring
  • More visual than standard df
  • Great for quick system checks
  • Use -i to check inode exhaustion
