info command

On Unix-like operating systems, the info command reads documentation stored in the info format, developed by the Free Software Foundation.


The info format is similar to that of man, the traditional Unix manual format. Info additionally provides a robust structure for linking pages together, similar to hyperlinks. Info pages are made using the texinfo tools, and can link with other pages, create menus and ease navigation in general.

The default location of info documentation is /usr/share/info.


info [OPTION]... [MENU-ITEM...]


-k, --apropos=STRING

look up STRING in all indices of all manuals.

-d, --directory=DIR

-f, --file=FILENAME

-h, --help

go to node pointed by index entry STRING.

-n, --node=NODENAME

specify nodes in first visited Info file.

-o, --output=FILENAME

output selected nodes to FILENAME.

-R, --raw-escapes

-O, --show-options, --usage

-w, --where, --location

MENU-OPTION, if present, is the menu entry to start from; it is searched for in all 'dir' files along INFOPATH. If it is not present, info merges all 'dir' files and shows the result. Any remaining arguments are treated as the names of menu items relative to the initial node visited.

For a summary of key bindings, type h within info.

info --show-options emacs
