________
The above listed pages are some of the most commonly used of the man (i.e., built-in online manual) pages that are included in major Linux distributions.
The brief discription after each topic is taken directly from the first line of the NAME section of the corresponding man page.
The word print that is used in some of the above discriptions is traditional UNIX terminology that means to output or to display and does not refer to the use of a printer.
Minor changes have been made to the original versions of the above-listed man pages, including adjustment of formatting for optimal web browser display and removal of obsolete links.
Links to LINFO pages on the same topic are enclosed in parenthesis.
