Redirect output to console and to file

[vasanthan111]

Hi friends,

Kindly help me regarding the issue Im facing with the below perl
script,

I have a below script which send the message to Console.

I need to modify this script it send message to a Log file.

Please find the below steps which i performed to send a message to
log.

Orginal Script:
===============

return -1 on error
#        0 pkg is starting or running and switchable
#        1 pkg is starting or running and not switchable
#        2 pkg is not running
_show_pkg() {
   local pkg=${1:-ALL}        #i.e 'GENPKG1,GENPKG3' or 'ALL' or
'GENPKG1' or ...
   local mode=${2:-silent}    #i.e 'normal'
 
   clustat -flx | perl -MXML::Twig -e'
       my %S = (started => q/UP/, recoverable => q/FAILED/, pending
=> q/FAILED/, stopped => q/DOWN/, failed => q/FAILED/, disabled => q/
DOWN/ );
       my @A = split /,/, $ARGV[0];
       my ($ret,$cs) = (0,0);
       my $twig = new XML::Twig(TwigRoots => {node => 1, group => 1},
                                TwigHandlers => { node  => sub {
my ($t,$n) = @_;
$cs = $ret = 1 unless ($n->att(rgmanager) eq q/1/ and $n->att(state)
eq q/1/);
},
                                                  group => sub {
my ($t,$g) = @_;
my $pkg = (split /:/,$g->att(name))[1];
return unless (q/ALL/ eq $A[0] or grep /$pkg/, @A);
my $owner = "on ".substr($g->att(owner),0,-2) if $g->att(state_str) eq
q/started/;
unless ($ARGV[1] eq q/silent/) {
  print("State of $pkg is $S{$g->att(state_str)}");
  print(" $owner and ",($g->att(restarts)>0 or $cs)?"not":"   ","
switchable") if $owner;
  print "\n";
}
$ret = 1 if $g->att(restarts)>0;
$ret = 2 unless $g->att(state_str) eq q/started/;
}});
       print(STDERR "Cannot open XML::Twig\n"), exit -1 unless
defined $twig; $twig->safe_parse(STDIN); exit $ret;
' ${pkg} ${mode}
}
 

Note ===> Steps

1. The output of the above script will display below information in
Screen ( console), it
will only display GENPKG{1..5} information on screen.

[root@incciozr0846 hbha]# show_pkg
State of GENPKG1 is FAILED
State of GENPKG2 is FAILED
State of GENPKG3 is FAILED
State of GENPKG4 is FAILED
State of GENPKG5 is FAILED
[root@incciozr0846 hbha]#

2. I want to send the same message to log file, So I adopted the
script as shown below.

my $file1 = "/tmp/pmon/usbs_manage_ha.log";
open FILE, ">>$file1" or die "unable to open $file1 $!";
 
unless ($ARGV[1] eq q/silent/) {
  print("State of $pkg is $S{$g->att(state_str)}");
  print FILE ("State of $pkg is $S{$g->att(state_str)} \n ");
  print(" $owner and ",($g->att(restarts)>0 or $cs)?"not":"   ","
switchable") if $owner ;
  print FILE (" $owner and ",($g->att(restarts)>0 or $cs)?"not":"
"," switchable \n" ) if $owner ;
  print "\n";
}
 close FILE or die;
 

3) Kindly note, Now im able to write to $file1 ("/tmp/pmon/
usbs_manage_ha.log"), but its continiously writing to the
$file1 in loop,

< extract of messgae in log >
