I have a subroutine that begins with a message ("Processing...") and
then proceeds to perform several gigs worth of file transfer via system
calls. Basically:
sub transfer {
print "Processing...\n";
foreach $e (@array) {
print "file $e\n";
system "cp $e"; #or whatever
}
print "...done\n";
}
Unfortunately, perl completes the entire (minutes long) routine BEFORE
it prints anything, so when the whole thing is done, suddenly the
"Processing...file X...file Y...file Z...done" appears.
Why? and is there a way around this? I would like to know what is
happening while it is happening, and not after it is finished.
