Because of the missing spaces. Debug run of prog4:
One line is due to the -v option (verbose), and the following line is after parsing (substitutions) due to the -x option (debug).
You see it recognizes 0==0 as one token, but it needs 3 token i.e. two spaces:
I notice that (Mandrake) Linux and Windows do not seem to operate alike in terms of installing third party software.
Windows, on one hand, creates icons and adds items to the Start Menu, with the help of the InstallShield--or equivalent, of course, but Linux, on the other hand, seems to care... (3 Replies)

Are the programs written on schedulers ,thread library , process management, memory management, et al called systems programs ?

Hello.
The last days I extended an open-source C++ library by some faster functions. This library provides a lot of short test programs which guarantee that the library works exactly.
The compilation of each test works in a Makefile automatically.
What I need is a shell script which... (5 Replies)
Hey guys,
Suppose i run passwd via bash shell. It is a suid program, which temporarily runs as root(owner) and modifies the user entries.
However, when i write a C file and give 4755 permission and root ownership to the 'a.out' file , it doesn't run as root in bash shell. I verified this by... (2 Replies)

io::async::protocol::linestream
IO::Async::Protocol::LineStream(3pm) User Contributed Perl Documentation IO::Async::Protocol::LineStream(3pm)NAME
"IO::Async::Protocol::LineStream" - stream-based protocols using lines of text
SYNOPSIS
Most likely this class will be subclassed to implement a particular network protocol.
package Net::Async::HelloWorld;
use strict;
use warnings;
use base qw( IO::Async::Protocol::LineStream );
sub on_read_line
{
my $self = shift;
my ( $line ) = @_;
if( $line =~ m/^HELLO (.*)/ ) {
my $name = $1;
$self->invoke_event( on_hello => $name );
}
}
sub send_hello
{
my $self = shift;
my ( $name ) = @_;
$self->write_line( "HELLO $name" );
}
This small example elides such details as error handling, which a real protocol implementation would be likely to contain.
DESCRIPTION EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_read_line $line
Invoked when a new complete line of input is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_read_line => CODE
CODE reference for the "on_read_line" event.
METHODS
$lineprotocol->write_line( $text )
Writes a line of text to the transport stream. The text will have the end-of-line marker appended to it; $text should not end with it.
