install-info makes, updates or removes entries in the Info directory,
the dir file. When updating or creating entries, if no description is
specified on the command line or in the Info file it attempts to guess
a description from the contents of the file.
See the description of the --section option for details of where the
entry will be placed and a description of the expected format of the
OPTIONS [Toc] [Back]
Gives the filename of the Info file whose menu entry is to be
created, updated or removed. If --remove-exactly is specified,
then filename should be the exact entry name to be removed (i.e.
"emacs-20/emacs" or "gcc"), otherwise the basename of this filename
is used as the referent of the menu entry which is created,
unless there's an overriding START-INFO-DIR entry inside the
given file. This file must therefore exist (or be about to be
installed, or have previously existed when removing an entry) in
the same directory as the dir file (see the --infodir option).
If filename ends in .gz it is taken to refer to a file compressed
with GNU gzip; if it doesn't exist, but a corresponding
filename.gz does, the latter is used instead.
When adding or updating entries the file must exist at the path
specified (possibly with an additional .gz extension).
Specifies that the entry for the file filename is to be removed;
by default entries are created or updated.
If the removal results in a section becoming empty the section
heading (and the spare blank line) will be removed as well,
unless this is the last section in the file or --keep-old is
specified. See the --section option for details about the
expected format of the dir file.
If there are several suitable entries in the dir file only those
in the first matching contiguous group will be removed and the
others silently ignored.
It is not an error for no suitable entry to be found, though
install-info will issue a warning unless the --quiet option was
When --remove is specified the --maxwidth, --align and --calign
formatting options are silently ignored.
This option is essentially the same as --remove except that
filename is taken as the exact entry to be removed, rather than
as the name of an existing file. This can be important when
trying to remove entries that refer to info files in subdirectories
(i.e. "emacs-20/emacs") because --remove will operate on
the basename of the given filename rather than the exact name
given. (i.e. --remove "emacs-20/emacs" would cause install-
info to look for "emacs", not "emacs-20/emacs").
--section regexp title
Specifies that, if a new entry is to be made, it should be
placed in a section of the dir file whose title matches regexp.
If no such section exists one will be created as the second last
section in the file (see below), with title title. A section is
a part of the dir menu delimited by blank lines; the first line
is assumed to be the title.
If a new entry is to be created install-info will attempt to
insert it within the section according in alphabetic order; if
the entries in the section aren't already sorted the new location
within the section will be unpredictable. The order of
existing entries will not be changed.
The default is to append new entries to the end of the file.
The last section (even if it only consists of the title line)
should always exist, to ensure that new sections are created in
the right place. The final section should be titled to reflect
the fact that Info files with no more well specified location
are appended to it.
If there is already an entry for the Info file being installed
it is replaced in situ with the new entry.
If a section is specified when removing an entry the section is
ignored and a warning is issued.
If a section is requested when adding an entry but the file contains
no section headings at all then install-info will create
both the requested section and a Miscellaneous section at the
end of the file.
Specifies that the dir file is, and the installed copy of the
new Info file was, is or will be located in infodir. The
default is /usr/info.
Specifies that the first line of the description should be
indented at least nnn characters; extra spaces will be added as
required. If necessary because of the length of the dir menu
entry details it may be offset more. The default is 27.
Specifies that the second and subsequent lines of the description
should be indented at least nnn characters. The default is
Specifies that the maximum width for the Info file is nnn. This
is used when wordwrapping the descriptive text. The default is
Prevents the usual display of the new menu entry just before it
is inserted, and of the messages announcing the replacement and
removal of existing entries and the creation and deletion of
--help Causes install-info to display its usage information and exit.
Causes install-info to display its version and copyright information
Specifies that the description to use after the menu entry in
new or updated entries be xxx. The default is to use the the
value specified in the Info file itself; this is found by
searching for a section of the form
* Auto-PGP: (auto-pgp). PGP under GNU Emacs.
If the entry found in the Info file itself extends across several
lines, each giving a menu entry, the text found in the file
is used verbatim. In this case the alphabetic ordering scheme
is turned off, and the entries are inserted at the top of section
in question. In this case the --menuentry, --maxwidth,
--align, --calign and --menuentry options are ignored.
If there is no dir entry in the file the program will try to
find a paragraph early in the file starting this file documents.
It will capitalise the first character of the remainder, and use
It is an error for none of these methods to yield a description.
If a description argument is given when --remove is specified it
is ignored and a warning is issued.
Specifies that the entry in the menu should be xxx. The default
is to use the the value specified in the Info file itself. If
this is not present the basename of the Info file is used (any
.info is deleted, and the entry is made mixed case). See above
for details of the format expected for the menu entry in the
When removing entries the value of the --menuentry option must
match the actual menu entry field in the menu item to be removed
(case not significant). If --menuentry is omitted no check on
the menu entry is done.
Inhibits the replacement of existing entries and the removal of
If the file being installed alreay has an entry in the directory
the old entry will be left alone instead of being replaced; the
default is to overwrite any old entry found with the newly generated
If --remove is specified --keep-old will prevent the removal of
the section heading which would otherwise happen if the section
is made empty by the removal.

processing steps are shown.
