info
The info command is a Linux command that can be used to display information about a variety of system topics. It is a powerful tool that can be used to troubleshoot problems, or to learn more about how the system works.
The info command will display a hierarchical tree of information about the topic. You can use the arrow keys to navigate through the tree, and the q key to exit
help
Usage: info [OPTION]... [MENU-ITEM...]
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.
Examples:
info show top-level dir menu
info info-stnd show the manual for this Info program
info emacs start at emacs node from top-level dir
info emacs buffers select buffers menu entry in emacs manual
info emacs -n Files start at Files node within emacs manual
info '(emacs)Files' alternative way to start at Files node
info --show-options emacs start at node with emacs' command line options
info --subnodes -o out.txt emacs
dump entire emacs manual to out.txt
info -f ./foo.info show file ./foo.info, not searching dirman
