Operation Manual

18.1.7 Man Pages and Info Pages
For some GNU applications (such as tar), the man pages are no longer maintained. For
these commands, use the --help option to get a quick overview of the info pages,
which provide more in-depth instructions. Info is GNU's hypertext system. Read an
introduction to this system by entering info info. Info pages can be viewed with
Emacs by entering emacs -f info or directly in a console with info. You can
also use tkinfo, xinfo or the help system to view info pages.
18.1.8 Selecting Man Pages Using the man
Command
With man man_page you normally display a man page for instant reading. Now, if
a man page with the same name exists in different sections, man prompts the user, the
page from which section shall be made visible. The user is then expected to type the
section as the answer.
If you want to return to the previous behavior, set MAN_POSIXLY_CORRECT=1 in a
shell initialization le such as ~/.bashrc.
18.1.9 Settings for GNU Emacs
GNU Emacs is a complex work environment. The following sections cover the con-
guration les processed when GNU Emacs is started. More information is available at
http://www.gnu.org/software/emacs/.
On start-up, Emacs reads several les containing the settings of the user, system admin-
istrator and distributor for customization or preconguration. The initialization le ~/
.emacs is installed to the home directories of the individual users from /etc/skel.
.emacs, in turn, reads the le /etc/skel/.gnu-emacs. To customize the program,
copy .gnu-emacs to the home directory (with cp /etc/skel/.gnu-emacs
~/.gnu-emacs) and make the desired settings there.
