On FreeBSD >= 13.0 the pdfjam script throws an error:

pdfjam "input.pdf" 1-20 -o output.pdf
sed: 1: "/\\\usepackage{hyperref}/d": RE error: trailing backslash (\)
sed: 1: "/\\\hypersetup.*/d": RE error: trailing backslash (\)
sed: 1: "/\\\usepackage.*{geomet ...": RE error: trailing backslash (\)
sed: 1: "/\\\usepackage.*{color}/d": RE error: trailing backslash (\)

While here, pet portfmt.
