In the command:

bash
git diff --word-diff=color --word-diff-regex=.

The --word-diff=color option highlights changes within lines by coloring the differences. The --word-diff-regex=. makes it so that every single character is treated as a "word" for the purpose of diffing, which means it will highlight every changed character in the diff.

How it works:

  • Added text is typically shown in green.
  • Removed text is typically shown in red.

Example:

If you change a line from:

bash
hello world

to:

bash
hello git

The output will highlight:

  • world in red (removed)
  • git in green (added)

Customizing Colors

If you want to customize the colors, you can use Git's color.diff configuration. For example:

bash
git config --global color.diff.old "red bold"
git config --global color.diff.new "green bold"

This will make removed text bold red and added text bold green.

Alternative: --color-words

You can also use:

bash
git diff --color-words

This is a shorthand for --word-diff=color --word-diff-regex=. and achieves the same effect.
