I'm no genius when it comes to Unix, however I do have some familiarity with the shell. I was courious as to weather system() calls made from perl get stored in a history file somewhere. I wrote a simple script that makes an "ls" call, ran it, watched the output to the screen, then checked my bash history and there was no trace of the system call, just the execution of my script.

My question is, is it possible that my perl script's system() calls are being recorded or stored some where else by the shell, or possibly by an administrator? Is that type of thing possible? Also, what about system() calls made from my CGI scripts, can/are those being recorded?
