Hi all, I am new to perl and have created the following script which should create an output file ( input.txt ) which I then run against a sh script which creates an ouput which I re direct to another file caled snapvault_status.out. The problem is that the last output file is empty but if I run the command on the command line I do get a filed file. I am sure my code is not great but I just started with perl :-) Any advice is appreciated. 
sub read_data
{
        system "ssh datab01 snapvault status | tail -n +3 >  /mnt/scri
+pts/lagtime/tmp/input.txt";
        system "ssh datab02 snapvault status | tail -n +3 >> /mnt/scri
+pts/lagtime/tmp/input.txt";
        system "ssh datab03 snapvault status | tail -n +3 >> /mnt/scri
+pts/lagtime/tmp/input.txt";
        print "Data is uitgelezen.\n";
}

sub create_correct_output
{
        open(MYINPUTFILE, "</mnt/scripts/lagtime/tmp/input.txt");
        while(<MYINPUTFILE>)
        {
                cat /mnt/scripts/lagtime/tmp/input.txt |awk '{printf "
+%1.50s\t%0.60s\t%0.45s\t %0.45s\n", $1, $2, $3, $4}' | sh /mnt/script
+s/lagtime/calculate_lag.sh > /tmp/snapvault_status.out.out;
        }
        print "data has been put in the right format.\n";
}
