# dehtmldiff(1)

get usable diff from an HTML page

## NAME

dehtmldiff - get usable diff from an HTML page

## SYNOPSIS

**dehtmldiff** \[*file*...\]

**dehtmldiff** {\[--help\] \| \[--version\]}

## DESCRIPTION

**dehtmldiff** creates usable diff files from HTML pages. This is useful in the scenario where a patch has been posted to a mailing list viewable via a web page.

The corrected diff is sent to standard output. Note that you will probably need to use the **-l** option when applying the patch, in order to ignore any whitespace differences there may be.

## OPTIONS

- **--help**

  Display a short usage message.

- **--version**

  Display the version number of dehtmldiff.

## LIMITATIONS

The way this command works is fairly primitive; it boils down to some simple text replacements, followed by an **unwrapdiff** pass. As a result, all of the limitations that apply to **unwrapdiff** also apply to **dehtmldiff**.
