info is a software utility which forms a hypertextual, multipage documentation and help viewer working on a command line interface, useful when there is no GUI available.

info processes info files, which are files in a special format[citation needed], (often generated from a Texinfo source), and presents the documentation as a tree, with simple commands to traverse the tree and to follow cross references. For instance

  • n goes to the next page.
  • p goes to the previous page.
  • u goes to the upper page.
  • l goes to the last visited node
  • Moving the cursor over a link (a word preceded by a * ) and pressing the enter key follows a cross reference.

The C implementation of info was designed as the main documentation system of GNU based Operating Systems and was then ported to other Unix-like operating systems. However, info files had already been in use on ITS emacs.
