QID 671103

The less utility is a text file browser that resembles more, but has more capabilities.
Less allows you to move backwards in the file as well as forwards.
Since less doesn't have to read the entire input file before it starts, less starts up more quickly than text editors (for example, vi).
You should install less because it is a basic utility for viewing text files, and you'll use it frequently.
Security fix(es): the is_utf8_well_formed function in gnu less before 475 allows remote attackers to have unspecified impact via malformed utf-8 characters, which triggers an out-of-bounds read.(cve-2014-9488)
