Hi @vinjam_likitha

This takes anything from start of the line to end of the line if it is Alphanumeric (alphabet or numbers).

^ - Indicates start of the line.
$ - End of the line.
a-zA-Z - Alphabets irrespective of the case.
0-9 - Numbers

Hi @vinjam_likitha

The regular expression ^[a-zA-Z0-9-]*$ matches any string that contains only letters (uppercase or lowercase), digits or hyphens.

• The ^ and $ characters are anchors that match the start and end of a line respectively.
• The * character matches zero or more occurrences of the preceding character.
• The square brackets [a-zA-Z0-9-] define a character set that matches any uppercase letter, lowercase letter, digit or hyphen.

Hope it will help you

Regards
Gokul
