Another way to handle this would be using substr:
As you will find out, there are many ways to do what
you ask. I have a regex:
#!perl -w
_ = 'abcdefghi';
s/(\w{3})(?=\w)/$1-/g;
printf "%-s\n", $_;
Output:
abc-def-ghi
The s/ express groups together three characters and then uses (?=\w) to
do the hypen if there is a following character if not, then no hyphen(end of
data).
Wags ;)
Help I have searched everywhere for
this
in Perl I have a value of
"ABCDEFGHI"
I want to parse this string so that it reads
"ABC-DEF-GHI"
In other words I want to be able to insert
dashes after the third and 6th character.
Is there anyway to do this in
Perl?
