Имя (Name)
dh_fixperms - fix permissions of files in package build
       directories
Синопсис (Synopsis)
dh_fixperms [debhelper options] [-Xitem]
Описание (Description)
dh_fixperms is a debhelper program that is responsible for
       setting the permissions of files and directories in package build
       directories to a sane state -- a state that complies with Debian
       policy.
       dh_fixperms makes all files in usr/share/doc in the package build
       directory (excluding files in the examples/ directory) be mode
       644. It also changes the permissions of all man pages to mode
       644. It removes group and other write permission from all files.
       It removes execute permissions from any libraries, headers, Perl
       modules, or desktop files that have it set. It makes all files in
       the standard bin and sbin directories, usr/games/ and etc/init.d
       executable (since v4). Finally, it removes the setuid and setgid
       bits from all files in the package.
       When the Rules-Requires-Root field has the (effective) value of
       binary-targets, dh_fixperms will also reset the ownership of all
       paths to "root:root".
Параметры (Options)
-Xitem, --exclude item
           Exclude files that contain item anywhere in their filename
           from having their permissions changed. You may use this
           option multiple times to build up a list of things to
           exclude.
