abc\b
abc when followed by a word boundary (e.g. in abc! but not in abcd)
perl\B
perl when not followed by a word boundary (e.g. in perlert but not in perl stuff)
\x
tells the regular expression parser to ignore white space that is neither
backslashed nor within a character class. You can use this to break up your
regular expression into (slightly) more readable parts.
/x
used to add regexps within other text. If the first character in a pattern is
forward slash '/', the '/' is treated as the delimiter. The pattern must contain a
second '/'. The pattern between ‘/’ will be taken as a regexp, and anything
after the second ‘/’ will be parsed as a list of regexp options ('i', 'x', etc). An
error occurs If the second '/' is missing. In regular expressions, the leading
and trailing space is treated as part of the regular expression.
