This is good advice overall!

For the OP, I just wanted to add that there are "better" alternatives to system and backticks. In this particular case, if there are no variables being interpolated into the command string, meaning it's safe enough to call the shell, IPC::System::Simple's run would probably be easiest, since it's just a replacement for system with better error handling.

use IPC::System::Simple qw/run/;
run q{ find /path/to/files -name '*.csv' | cpio -pdm /target };

Otherwise, e.g. if variables are being interpolated into the command, things can get more complicated - I wrote about the whole topic at length here.
