The grep command in Linux is a utility used to search any given input files for one or more matching words or patterns. It is used to search a single file or an entire directory, including child directories, for a matching string.
The fgrep command differs from both grep and egrep in the sense that it interprets PATTERN as a list of fixed strings (instead of regular expressions), separated by newlines.
Going by the official documentation, there isn't any difference between fgrep and the grep -F command. However, there's reportedly one major difference between the two tools: the string matching algorithm they use. While fgrep uses the Aho-Corasick algorithm, grep makes use of a modified version of Commentz-Walter.
