It also accepts a limit clause in case you need a specified number of result elements. It accepts arguments similar to split() except that the splitting is done in reverse order. Map reverse split(/$pattern/, scalar reverse($expr), $limit) # 4) Reverse each string within the result array

# 3) Reverse split()'s result array element order My $limit = # Number of chunks to split into My $pattern = # Precompiled regex pattern (i.e. # The only exception is that the pattern must be a precompiled regex (i.e. I'm a bit late to this question, but I put together a more generic solution: # Similar to split() except pattern is applied backwards from the end of the string Consider the following expressions evaluated in list context (each returned list is provided in the associated comment): split(/-|,/, '1-10,20', 3) Also, note that any such additional field is produced whenever there is a separator (that is, whenever a split occurs), and such an additional field does not count towards the LIMIT.

If the PATTERN contains capturing groups, then for each separator, an additional field is produced for each substring captured by a group (in the order in which the groups are specified, as per backreferences) if any group does not match, then it captures the undef value instead of a substring. # Capturing everything after ':' that is not ':' and until the end of the string So I want to expand it with an extract from the perldoc split that explains this behavior, for the sake of new readers. But I found the answer from YOU very interesting as I didn't know split could work like that.
