info (Unix)
From Wikipedia, the free encyclopedia
info is a command line utility initially written for use with GNU/Linux and then ported to other Unix-like operating systems. It is a kind of hypertextual, multipage documentation and help viewer working on a terminal, so no GUI is needed; info processes info files, which are Texinfo formatted files, 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 takes you to the last(visited) node
- To follow a cross reference, you can move the cursor on a link (a word preceded by a *) and press enter.
