Re: regex for a phrase beginning with some chars

The \b anchor may also be useful, depending on how you define a "word":

use strict;
use warnings;

while (<DATA>) {
    print if /^ascii\b/i;
}

__DATA__
does not begin with ascii
ascii is the one
AsCii works too
asciibetically sorted
[download]

Prints:

ascii is the one
AsCii works too
[download]

Updated: Added "asciibetically" line to demonstrate \b (johngg++)

I think your application of the `\b` anchor might better have been demonstrated with a string like "asciibetically sorted" which would show that there is no word boundary after the "ascii" part. Cheers, JohnGG	[reply] [d/l]
