Re^2: glob: where are the full paths?

For example, glob '{a,b}{c,d}' doesn't returns paths at all.

use strict;
use warnings;
use 5.010;

say glob '{a,b}{c,d}';

Uhm, where's the documentation for that?

Ok, here's part of it:

In list context, returns a (possibly empty) list of filename expansions on the value of EXPR such as the standard Unix shell /bin/csh would do. In scalar context, glob iterates through such filename expansions, returning undef when the list is exhausted.

What do the curly braces do?

Its in the manual , See File::Glob for details. The metanotation a{b,c,d}e is a shorthand for abe ace ade . Left to right order is preserved, with results of matches being sorted separately at a low level to preserve this order. As a special case {, }, and {} are passed undisturbed. `$ perl -le"print for glob shift" "abe ace ade" abe ace ade $ perl -le"print for glob shift" "see also sea shore " see also sea shore $` [download]	[reply] [d/l]
