Well, yeah, split
by default - sort of. However, the first argument, if any,
is the regular expression. Only if
the first argument is missing, it results to the default.
In your example, which of course you haven't tested, you
one argument. One argument split
will split $_
, using the regular expression
given - in your case, the value of $line
Which is not at all what you want.
I said "sort of", meaning that the default case (that is,
no arguments to split) trailing empty fields
are removed - just like in awk. Which doesn't
happen if you use /\s+/ as first argument.
Use ' ' to get the effect of the default
You know, you would have saved a lot of trouble, from both
you and me (and people who thought you spoke the truth and
used your suggestion) if you had either tried out your
suggestion or had consulted the manual page. But I guess a
quick typing without thinking is the fast lane to fame.
