Re^3: problem count the number of words -- oneliner

[pme]

Hi kschwab,

Are you sure? This one gives the same result like wc.

perl -ne 's/\S+/$i++/egi;END{print "$i\n"}' f1 f2

Guess it depends on what OP means by "all words", but sure.

# works like wc
perl -ne 's/\s+/$i++/eg;END{print "$i\n"}' f1 f2

Not sure why you have the "i" modifier.

You are right, we do not need "i".
