NAME
open - perl pragma to set default PerlIO layers for input and output
SYNOPSIS
use open IN => ":crlf", OUT => ":bytes";
use open OUT => ':utf8';
use open IO => ":encoding(iso-8859-7)";
use open IO => ':locale';
use open ':utf8';
use open ':locale';
use open ':encoding(iso-8859-7)';
use open ':std';
DESCRIPTION
Full-fledged support for I/O layers is now implemented provided Perl is
configured to use PerlIO as its IO system (which is now the default).
The "open" pragma serves as one of the interfaces to declare default
"layers" (also known as "disciplines") for all I/O. Any two-argument
open(), readpipe() (aka qx//) and similar operators found within the
lexical scope of this pragma will use the declared defaults. Three-
argument opens are not affected by this pragma since there you (can)
explicitly specify the layers and are supposed to know what you are
doing.
With the "IN" subpragma you can declare the default layers of input
streams, and with the "OUT" subpragma you can declare the default lay-
ers of output streams. With the "IO" subpragma you can control both
input and output streams simultaneously.
If you have a legacy encoding, you can use the ":encoding(...)" tag.
if you want to set your encoding layers based on your locale environ-
ment variables, you can use the ":locale" tag. For example:
$ENV{LANG} = 'ru_RU.KOI8-R';
# the :locale will probe the locale environment variables like LANG
use open OUT => ':locale';
open(O, ">koi8");
print O chr(0x430); # Unicode CYRILLIC SMALL LETTER A = KOI8-R 0xc1
close O;
open(I, "), "\n"; # this should print 0xc1
close I;
These are equivalent
use open ':utf8';
use open IO => ':utf8';
as are these
use open ':locale';
use open IO => ':locale';
and these
use open ':encoding(iso-8859-7)';
use open IO => ':encoding(iso-8859-7)';
The matching of encoding names is loose: case does not matter, and many
encodings have several aliases. See Encode::Supported for details and
the list of supported locales.
Note that ":utf8" PerlIO layer must always be specified exactly like
that, it is not subject to the loose matching of encoding names.
When open() is given an explicit list of layers they are appended to
the list declared using this pragma.
The ":std" subpragma on its own has no effect, but if combined with the
":utf8" or ":encoding" subpragmas, it converts the standard filehandles
(STDIN, STDOUT, STDERR) to comply with encoding selected for input/out-
put handles. For example, if both input and out are chosen to be
":utf8", a ":std" will mean that STDIN, STDOUT, and STDERR are also in
":utf8". On the other hand, if only output is chosen to be in ":encod-
ing(koi8r)", a ":std" will cause only the STDOUT and STDERR to be in
"koi8r". The ":locale" subpragma implicitly turns on ":std".
The logic of ":locale" is described in full in "encoding", but in short
it is first trying nl_langinfo(CODESET) and then guessing from the
LC_ALL and LANG locale environment variables.
Directory handles may also support PerlIO layers in the future.
NONPERLIO FUNCTIONALITY
If Perl is not built to use PerlIO as its IO system then only the two
pseudo-layers ":bytes" and ":crlf" are available.
The ":bytes" layer corresponds to "binary mode" and the ":crlf" layer
corresponds to "text mode" on platforms that distinguish between the
two modes when opening files (which is many DOS-like platforms, includ-
ing Windows). These two layers are no-ops on platforms where binmode()
is a no-op, but perform their functions everywhere if PerlIO is
enabled.
IMPLEMENTATION DETAILS
There is a class method in "PerlIO::Layer" "find" which is implemented
as XS code. It is called by "import" to validate the layers:
PerlIO::Layer::->find("perlio")
The return value (if defined) is a Perl object, of class "Per-
lIO::Layer" which is created by the C code in perlio.c. As yet there
is nothing useful you can do with the object at the perl level.

OPENVT(1) Linux User's Manual OPENVT(1)
NAME
openvt - start a program on a new virtual terminal (VT).
SYNOPSIS
openvt [-c vtnumber] [-f] [-s] [-u] [-l] [-v] [--] command com-
mand_options
DESCRIPTION
openvt will find the first available VT, and run on it the given com-
mand with the given command options, standard input, output and error
are directed to that terminal. The current search path ($PATH) is used
to find the requested command. If no command is specified then the
environment variable $SHELL is used.
OPTIONS
-c vtnumber
Use the given VT number and not the first available. Note you
must have write access to the supplied VT for this to work.
-f Force opening a VT: don't try to check if a VT is already in
use.
-s Switch to the new VT when starting the command. The VT of the
new command will be made the new current VT.
-u Figure out the owner of the current VT, and run login as that
user. Suitable to be called by init. Shouldn't be used with -c
or -l.
-l Make the command a login shell. A - is prepended to the name of
the command to be executed.
-v Be a bit more verbose.
-w wait for command to complete. If -w and -s are used together
then openvt will switch back to the controlling terminal when
the command completes.
-- end of options to openvt.
EXAMPLES
openvt can be used to start a shell on the next free VT, by using the
command:
openvt bash
To start the shell as a login shell, use:
openvt -l bash
SEE ALSO
chvt(1), login(1).
