Trying to read data multiple times
I am developing a script to automate Global Mirroring on IBM DS8100's. Part of the process is to establish a global copy and wait until the paired LUN's Out of Sync tracks goes to zero. I can issue a command to display the ouput and am trying to use AWK to read the appropriate field. I am simulating the command output (since I can't do it live) by capturing the output to a file and then reading the file. My problem is I haven't figured out how to use getline to read the file multiple times. Here is what I'm attempting:

while ( EndofRout > 0 ) {
NR = 1
while ( (getline < "/tmp/output.orig") > 0 ) {
OutSyncTrack[NR] = $7
NR++
} # end of while getline to build OutSyncTrack array
#
#
for ( x = 1; x <= NR; ++x ) {
EndofRout = 0
print "EndofRout is " EndofRout
if ( OutSyncTrack[x] != 0 )
EndofRout = 1
continue
}
}

The field $7 starts off as a high number then gradually goes to zero. I can simulate this by editing the file, but my problem is that it is only reading the file once even though $7 is not zero. Any help will be greatly appreciated. Thanks in advance.

padre::sync

Padre::Sync(3pm)					User Contributed Perl Documentation					  Padre::Sync(3pm)

NAME

       Padre::Sync - Utility functions for handling remote Configuration Syncing

DESCRIPTION

       The "Padre::Sync" class contains logic for communicating with a remote Madre::Sync server. This class interacts with the
       Padre::Wx::Dialog::Sync class for user interface display.

METHODS

   "new"
       The constructor returns a new "Padre::Sync" object, but you should normally access it via the main Padre object:

	 my $manager = Padre->ide->config_sync;

       First argument should be a Padre object.

   "main"
       A convenience method to get to the main window.

   "config"
       A convenience method to get to the config object

   "ua"
       A convenience method to get to the useragent object

   "register"
       Attempts to register a user account with the information provided on the Sync server.

       Parameters: a list of key value pairs to be interpreted as POST parameters

       Returns error string if user state is already logged in or serverside error occurs.

   "login"
       Will log in to remote Sync server using given credentials. State will be updated if login successful.

   "logout"
       If currently logged in, will log the Sync session out from the server.  State will be updated.

   "server_delete"
       Given a logged in session, will attempt to delete the config currently stored on the Sync server (if one currently exists).  Will fail if
       not logged in.

   "local_to_server"
       Given a logged in session, will attempt to place the current local config to the Sync server.

   "server_to_local"
       Given a logged in session, will replace the local config with what is stored on the server.  TODO: is validation of config before
       replacement required?

   "english_status"
       Will return a string explaining current state of Sync dependent on $self->{state}
