What are those backticks doing in the command? You're telling the shell execute the cp command, and to execute whatever the cp command writes to STDOUT (which is probably not much).

What do you mean by the file "not be able to be seen"? You give a full path to the file, so it can't be a working directory issue.

Finally, whether or not you can execute a command from the shell started by clt, and if, how, is something that the manual page of clt might be able to tell you. But it's not a Perl issue (and neither is it a Unix issue).
