The following works for me.
use POSIX ":sys_wait_h";
my $var1 = 3;
my $var2 = 5;
system ("./perl651.sh", $var1, $var2);
my $status = $?;
if ($status == -1)
print "failed to execute: $!\n";
print "exited with return code ".WEXITSTATUS($status)."\n";
print "terminated by signal ".WTERMSIG($status)."\n";
print "other status $status\n";
Shell code (filename = perl651.sh)
if [ $# -ne 2 ]
echo "Expecting 2 arguments, only $# provided"
# return code is sum of two arguments
RC=`expr $1 + $2`
echo "Sum of $1 + $2 is $RC"
Sum of 3 + 5 is 8
exited with return code 8
