Just a naive question: why do you run your system commend in the background if you want to wait for it to complete before you proceed? In other words, it seems to me that you don't really need the ampersand and the nohup statement. If you remove them, your Perl script will wait for the system command to complete before proceeding to execute the next code statement. In a way, this is not a Perl question, since you would have the same problem if you did that in a shell script.

Just as a side comment, please note that ¨Perl is compiling the whole script before it starts executing anything (except for special phaser blocks such as BEGIN { ...}).

Update: fixed a typo.
