Open Source
Info pages, which are another component of the built-in help system, are available for many software products from the GNU Project.[19] To get started, try typing info
or info info
or info some_program
(such as info gcc
) at the prompt. The navigation commands are different from those for the man pages: ? provides a list of commands and h starts a tutorial (but q still quits). It is worth checking the info pages for information on specific GNU programs.[20] You can also find the built-in documentation for the GNU C library (or glibc
) by typing info libc
at the prompt.[21]
