3.22 Comparison

This section describes commands which compare files and/or buffers against each other.

Diff

Editor Command

Arguments: [ file1 ] [ file2 ]
Key sequence: None

Compares the current buffer with another file.

A prefix argument makes it compare any two files, prompting you for both filenames.

Diff Ignoring Whitespace

Editor Command

Arguments: [ file1 ] [ file2 ]
Key sequence: None

Compares the current buffer with another file, like Diff but ignoring whitespace.

A prefix argument is interpreted in the same way as by Diff.
