The grep family of commands is specifically designed for searching plain-text data sets for lines that match a regular expression.
grep: The standard Global Regular Expression Print command.
egrep: (Extended grep) used for searching using extended regular expressions.
fgrep: (Fixed grep) used for searching for fixed strings rather than regular expressions, which is faster for simple text searches
