Understanding the RegEx!

Question

Literal VS Metacharacter VS RegEx

Literal: consists of usual words.
Ex: "solo" . In this case All the "solo"-s available inside the context will be matched.

Metacharacter: are used to specify more general search terms that we would like to identify.
Ex: " ^ " metachar is used to specify the start of the sentence.

RegEx: is a pattern that the regular expression engine attempts to match in input text.
Non-formally speaking : uses metachars and literals to achieve more general
search results.
Ex: " ^apathy ":In this case, we give more general scope of matching, to match all the lines starting with apathy.

Last example to make the difference clear:

Ex: flower | ^[Ff]ruit

In the example above we have 2 parts seperated by OR(|).
The first part is just a literal, the second is a regex.

So all the flowers and fruits will be matched, where both the fruits starting with upper and lower case will be matched(as we have [Ff]), but only the ones that are the beginning of a line (as we have ^ metachar) .
