Defining the header in groff mm does not change it in the first page

I am trying to define a custom header in groff using mm macros.

If I define .PH it takes effect on page 2, but not on page 1.

Why is this happening?

% cat sample2.mm

This is what I get.

For page 1, the header is the default one: page1

For page 2, the header is the expected one: Page2

Solution

  • .PH defines the page header for the next page and further. If anything has been done on the first page, including seeing some comments, the headers in .PH arguments are used from the second page.

    If you move the .PH line to the top, it will be processed for the first page too. Don't put any comments above it.
