UNIX Regular Expressions
Appendix A
127
When you attemp to match the pipe (|), ampersand (&) or the comma (,) character in a
regular expression, you must escape those special characters using a backslash (\)
character because these three characters also have special meaning (i.e., are used as
delimiters) by the parser of the template property syntax. For example, a pathname of
´a\|b will have the backslash removed by the template property parser before being
passed as a regular expression to the regular expression parser (i.e., as ´a|b ). To match
a pathname that contains one of these three characters, one must escape the backslash
and the special character itself (i.e., ´a\\\|b will be passed to the regular expression
parser as ´a\|b).
