Those are alternate delimeters. See the "substitution operator" in perlop. Also read perlre. There is a wealth of information on perldoc.perl.org.	[reply]

You can use any pair of non-alphanumeric, non-whitespace charaters as delimiters of a regex pattern. So these regexes are equivalent: `s/a/b/; s"a"b"; s^a^b^; s{a}{b}; s(a)[b];` [download] Only ' is an exception, this character prevents variable interpolation if used as delimiter Advantage is that you can use / inside them without escaping the character. Also it could be argued that {} [] or () as delimiters just look better, especially for complex patterns. Edit: Deleted one erraneous example found by ikegami	[reply] [d/l]

`>perl -ce"/a/b/" Bareword found where operator expected at -e line 1, near "/a/b" (Missing operator before b?) syntax error at -e line 1, near "/a/b" -e had compilation errors.` [download] `/a/b/` is the same as `m/a/ b /`	[reply] [d/l] [select]
