Hi,...

I'm assuming you're using Windows... DEL is part of CMD.EXE (or Command.COM) not a program in its own right... perhaps you should look at unlink (perldoc -f unlink) instead?

HTH - Mark

Update:

Your system("echo %errorlevel%") call is spawned in a different CMD.EXE than your system("del tmp.txt"); so even if it worked it wouldn't be what you wanted... If you need to know if the file was there first you can do

#simplest format
if (-e $filename){
    if ((unlink($filename)) {
        print STDERR "File $filename deleted.\n";
    }else{
        print SDTERR "Couldn't delete $filename $!\n";
    }
}else{
    print STDERR "File didn't exist\n";
}
