[[Category:Command Group: Strings]]
In order to adjust the behaviour of the regex commands, certain flags can be set when using them. Flags are specified at the end of the pattern and start with <tt>/</tt>. Flags need to be lowercase. If there are any non-flag characters in the flags they will be ignored and considered part of the pattern itself.
<code>"I'm a coOkIe clicker" [[regexMatch]] ".*cookie.*/gio"{{cc|Flag g, i and o are set}}</code>
