hi,
I want to write a program that will listen to tty and without knowing
why i do I typed the following
use strict;
my $log_name = $ARGV[1];
my $tty_port = $ARGV[0];
print "Log name = = $log_name \n";
#print "Entering the LOOP";
if(-e $tty_port) {
#print " Listening to $tty_port\n";
open(FL, "< $tty_port");
print "ok I opened the $tty_port\n";
while (<FL>) {
#print "opening file for writing into \n";
open WL, ">> $log_name" or die $!;
print WL $_ ;
close(WL);
}
close(FL);
}
======
Now I made a call to the program by passing two parameters
1. /dev/tty --- the tty
2. log name : /epihome/ompe/ompe/ompe/scripts/vb_prl/gtemp/good.log
======
I made the call like
perl callsc.pl /dev/tty /epihome/ompe/ompe/ompe/scripts/vb_prl/gtemp/
good.log &
It did not listen to the port but exited with the folloing message
[1] + Stopped (SIGTTIN) perl /epihome/ompe/ompe/ompe/scripts/
vb_prl/gtemp/callsc.pl /dev/tty /epihome/ompe/ompe/ompe/scripts/vb_prl/
gtemp/good.log &
Is there any alternative way I can try this?
