I found this little snippet in a post (from 2000) by Randal L. Schwartz:
http://www.perlmonks.org/?node_id=20235
The discussion was about:
File::Slurp allows you read a filehandle into a scalar. However there
is another way to do this without having to load an extra module at
runtime. The select statement changes $/ (the input record separator)
to a null character instead of a \n. And there you go..
And a previous poster shows an example of doing it with `select';
Randal responded:
I just go:
my $contents = do { local $/; <HANDLE> };
The $/ variable is not per-filehandle, so no need to select.
I have not been able to get this to work.
My code uses the old style `open' just in case it would matter:
use strict;
use warnings;
my $file = '.bashrc';
open(FH, $file) or die "Can't open $file: $!";
my $content = do { local $/; <FH> };
print $content . "\n";
But when I print `$content' my .bashrc file looks totally normal.
I expected to see it as one long string.
I also tried it with nothing in the script except(`use' stuff) and
Randal's code slightly modified:
use strict;
use warnings;
my $content = do { local $/; <> };
print $content . "\n";
Of course it changed nothing. The file was still printed with all
newlines in place.
Should I be seeing a file with no newlines being printed as a very
long line?
