INFO(1)

NAME
info - read Info documents

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

DESCRIPTION
Read documentation in Info format.

  Frequently-used options:

-a, --all
    use all matching manuals

-k, --apropos=STRING
    look up STRING in all indices of all manuals

-d, --directory=DIR
    add DIR to INFOPATH

-f, --file=MANUAL
    specify Info manual to visit

-h, --help
    display this help and exit

--index-search=STRING
    go to node pointed by index entry STRING

-n, --node=NODENAME
    specify nodes in first visited Info file

-o, --output=FILE
    output selected nodes to FILE

-O, --show-options, --usage
    go to command-line options node

--subnodes
    recursively output menu items

-v, --variable VAR=VALUE
    assign VALUE to Info variable VAR

--version
    display version information and exit

-w, --where, --location
    print physical location of Info file

The first non-option argument, 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.
