No, Perl does not use an %ENV variable to figure out which shell to use for system. For Unix it is always /bin/sh (unless you changed that for some obscure reason when you built Perl).

If you always use the multi-argument form of system, then a shell will never be invoked. Accomplishing this can be made easier by using IPC::Open2 and/or IPC::Open3 to do I/O redirection w/o using a shell.
