Regex tips and tricks

Following are some of the useful JavaScript-based Regex patterns that can be used while searching the configuration options:

• .* - To search for zero or more occurrences of the string that follows the special character combination.

• \d - To search for any digit. Equivalent to [0-9]. For example, \d or [0-9] matches 6 in IPV6.

• ^...$ - To search for a string of finite length, starting and ending with definite characters. For example, ^c....._m...m$ matches CONFIG_MODEM.
