Re^4: Running a process in the background

Hello, Remember to check for a fork error after forking:


if (my $pid = fork) {
    ## Parent
  } elsif ($pid == 0) {
    ## Child
  } else {
    ## Error, $pid is undefined
}

`undef == 0` - use `defined` instead: `if (my $pid = fork) { ## Parent } elsif (defined $pid) { ## Child } else { ## Error, $pid is undefined }` [download] "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l] [select]
