I just want the number of blocks, and I can get it with the following command in a bash shell on Solaris 10:
$4 is being interpolated and since it's undefined what's handed to the shell is:
my $outVar = `df | grep c0d0s3 | awk -F '{print}'`;
Just escape the $4:
my $outVar = `df | grep c0d0s3 | awk -F '{print \$4}'`;
