PerlIO::scalar - in-memory IO, scalar IO
SYNOPSIS
my $scalar = '';
...
open my $fh, "<", $scalar or die;
open my $fh, ">", $scalar or die;
open my $fh, ">>", $scalar or die;
or
my $scalar = '';
...
open my $fh, "<:scalar", $scalar or die;
open my $fh, ">:scalar", $scalar or die;
open my $fh, ">>:scalar", $scalar or die;
DESCRIPTION
A filehandle is opened but the file operations are performed "in-memory" on a scalar variable. All the normal file operations can be
performed on the handle. The scalar is considered a stream of bytes. Currently fileno($fh) returns -1.
IMPLEMENTATION NOTE
"PerlIO::scalar" only exists to use XSLoader to load C code that provides support for treating a scalar as an "in memory" file. One does
not need to explicitly "use PerlIO::scalar".

METHODS

o $newvalue (scalar)
scalar = $object->base_width ($newvalue=undef)
o $newvalue (scalar)

o $flags (Gtk2::Gdk::WindowHints) optional, usually inferred from $geometry
The $flags argument, describing which fields in the geometry are valid, is optional. If omitted it will be inferred from the geometry
itself.

hi,
I am searching for a native tool on MacOS that can increase the resolution of a group of image files whose aspect ratios (file width versus height) vary widely. There are numerous files so I don't wish to do this manually. Someone suggested the sips command with the resampling option but... (5 Replies)

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:
