Consider the following rules and guidelines when you use a line terminator:
mode is active, the Rule Engine recognizes the line terminators as new line characters.
You can specify the
flag to indicate that the period character matches any character except for a line terminator.
You can use the caret and dollar characters to ignore line terminators and to match the beginning and end of the input sequence.
mode is active, the caret characters match the beginning of the input sequence and after any line terminator. The end of the input is not included. The dollar symbol matches before a line terminator and at the end of the input sequence.
