LEARN ABOUT LINUX
info
INFO(1) User Commands INFO(1) NAME
info - read Info documents SYNOPSIS
info [OPTION]... [MENU-ITEM...] DESCRIPTION
Read documentation in Info format. OPTIONS
-k, --apropos=STRING look up STRING in all indices of all manuals. -d, --directory=DIR add DIR to INFOPATH. --dribble=FILENAME remember user keystrokes in FILENAME. -f, --file=FILENAME specify Info file 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=FILENAME output selected nodes to FILENAME. -R, --raw-escapes output "raw" ANSI escapes (default). --no-raw-escapes output escapes as literal text. --restore=FILENAME read initial keystrokes from FILENAME. -O, --show-options, --usage go to command-line options node. --subnodes recursively output menu items. --vi-keys use vi-like and less-like key bindings. --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 show the general manual for Info readers info info-stnd show the manual specific to this Info program info emacs start at emacs node from top-level dir info emacs buffers start at buffers node within emacs manual info --show-options emacs start at node with emacs' command line options info --subnodes -o out.txt emacs dump entire manual to out.txt info -f ./foo.info show file ./foo.info, not searching dir REPORTING BUGS
