Having a problem with system() recognizing a string literal. OS - Unix (Sun solaris) Code snippet below: CONFIG file has an entry as so: 
CMD|/opt/sudo/sudo /usr/bin/su - $ENV{LOGNAME} -c "$someScript"

[download]
I read this config file and assign $cmd as so 
my $cmd = (split /\|/, $configLine)[1];
system("$cmd");

[download]
I was expecting thaT the value for the $ENV{LOGNAME} would be substituted in the system(). But for some reason it is is not capturing the value. Here's whats confusing -I explictly assigned $cmd as 
my $cmd = "/opt/sudo/sudo /usr/bin/su - $ENV{LOGNAME} -c \"$someScript
+\" ";
system("$cmd");

[download]
Now it recognizes the value of $ENV{LOGNAME}.. What am i doing wrong in the config file? Note: I have to read commands from the config file only per design. Any help is greately appreciated. Thanks
