didess has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks! I know there are two forms for submitting a command to system :

One through the shell with the command and its parameters in one single scalar system('echo $LANG'); for example.

One without the shell, with the command and its parameters in a list. like system('echo','$LANG');

With this second form, the command echo will print '$LANG' without any resolution of the variable LANG.

Can I get these two different ways , and how if yes, with the qx syntax : qx {echo $LANG} ?

Thanks to you!
