THAT ====^^^ is your problem.
---------- perldoc -f split ----------
split /PATTERN/,EXPR,LIMIT
split /PATTERN/,EXPR
split /PATTERN/
...
---------- perldoc -f split ----------
See the '/' around PATTERN? That means that we're dealing with a
regular expression, and '|' is a special char for regexps. Your split
says "Split at NOTHING OR NOTHING", since that '|' basically means "OR".
Since NOTHING can't be matched you split after each character.
If you write it like "split /\|/, $line" it'll work.
More information can be found in
perldoc perlrequick
or
perldoc perlretut
The section you're looking for starts with 'Matching this or that' in
both documents.
Take a look at 'perldoc -f quotemeta' if you're running into similar
problems when using more complex matching and generated search
expressions.
