watchdiff

Alternative to watch with visual indication of what was added or removed every time a command was run.

Executes a program periodically and displays the output with colors indicating changes as a diff. Additions are marked in green, and deletions in red. Colors will fade after consecutive executions with the same output.

Similar to watch -d, but also displays the output that was overwritten.
