"Break" from a Loop
I created a script-
PHP Code:
while [ ${Check} = "N" ]
do
echo "try this"
for file in `cat file_list`
do
echo $file
if [ ${NewCheck} = "N" ]
then
sVar="F"
else
[B]break[/B]
fi
done
sleep 300
done
EOF
exit 0
Here we have "while" loop then a "for" loop and finally an "if" conditional. Now when the "if" condition fails then I use "break".
My qusn is will this BREAK , break it out of "For" Loop or totally out of "While" loop i.e. exit it out of script.
Expert opinion needed. Dont have enough time to test the it myself.
Thanks
Sumeet

io::async::loop::glib
IO::Async::Loop::Glib(3pm) User Contributed Perl Documentation IO::Async::Loop::Glib(3pm)
NAME
"IO::Async::Loop::Glib" - use "IO::Async" with Glib or GTK
SYNOPSIS
use IO::Async::Loop::Glib;
my $loop = IO::Async::Loop::Glib->new();
$loop->add( ... );
...
# Rest of GLib/Gtk program that uses GLib
Glib::MainLoop->new->run();
Or
$loop->loop_forever();
Or
while(1) {
$loop->loop_once();
}
DESCRIPTION
This subclass of "IO::Async::Loop" uses the "Glib::MainLoop" to perform read-ready and write-ready tests.
The appropriate "Glib::IO" sources are added or removed from the "Glib::MainLoop" when notifiers are added or removed from the set, or when
they change their "want_writeready" status. The callbacks are called automatically by Glib itself; no special methods on this loop object
are required.
CONSTRUCTOR
$loop = IO::Async::Loop::Glib->new()
This function returns a new instance of a "IO::Async::Loop::Glib" object. It takes no special arguments.
METHODS
There are no special methods in this subclass, other than those provided by the "IO::Async::Loop" base class.
$count = $loop->loop_once( $timeout )
This method calls the "iteration()" method on the underlying "Glib::MainContext". If a timeout value is supplied, then a Glib timeout will
be installed, to interrupt the loop at that time. If Glib indicates that any callbacks were fired, then this method will return 1 (however,
it does not mean that any "IO::Async" callbacks were invoked, as there may be other parts of code sharing the Glib main context. Otherwise,
it will return 0.

o Glib - Perl wrappers for the GLib utility and Object libraries
o Gtk2 - Perl interface to the 2.x series of the Gimp Toolkit library
