Best way to remove last word from a string

[Guy Smiley]

Hello,

After googling and perldoc'ing, I'm still struggling to figure out the best
way to remove the last word from a string (without any line-ends or carriage
returns).

$output = "data1 data2 data3 data4";

Would like to see:

data1 data2 data3

I need to get this done soon and I have a long way to go before I understand
how to do this with a regex.

I'm also thinking that I could split the string at the spaces and construct
a new string by iterating through the array count minus 1. But this seems
like overkill.

my @datas = split(' ', $output);
for-loop
etc;

Any insight is greatly appreciated.

Which parts of the docs have you studied?

Then you'd better start right away, eh?

Well, if you start with splitting like that, you can make use of the
pop() function instead of iterating through the array. Doing so would
not be overkill IMO.
