regular-expression [character]
Enter a regular expression then use one or a combination of
the following characters to match:
• . = (period) any single character (including a white
space)
• * = (asterisk) the sequences in a pattern (0 or more
sequences)
• + = (plus) the sequences in a pattern (1 or more
sequences)
• ? = (question mark) sequences in a pattern (either 0 or 1
sequences). You must enter an escape sequence
(CTRL+v) prior to entering the ? regular
expression.
• [ ] = (brackets) a range of single-character patterns.
• ( ) = (parenthesis) groups a series of pattern elements
to a single element
• { } = (braces) minimum and the maximum match count
• ^ = (caret) the beginning of the input string. If the caret
is used at the beginning of a sequence or range, it
matches on everything BUT the characters specified.
• $ = (dollar sign) the end of the output string.
