For example:#

.od matches any three-character string ending with "od", including "hod", "mod", and "nod".

[hm]od matches "hod" and "mod".

[^m]od matches all strings matched by .od except "mod".

^[hm]od matches "hod" and "mod", but only at the beginning of the string or line.

[hm]od$ matches "hod" and "mod", but only at the end of the string or line.

\[.\] matches any single character surrounded by "[" and "]" since the brackets are escaped, for example: "[a]" and "[b]".
