in reply to command line switches (array)

If you really can't use any modules, even a core one that ships with Perl itself (and you should ask why not, if that is the case), then simply scan over the @ARGV array and take appropriate actions, something like (untested):

for (my $i=; $i < @ARGV; $i++)) { if ($ARGV[$i] eq "-l") { warn "Logfile $ARGV[$i+1] missing\n" unless -e $ARGV[$i+1]; } elsif ($ARGV[$i] eq "-u") { warn "Useraccounts $ARGV[$i+1] missing\n" unless -e $ARGV[$i+1]; } else { warn "Invalid switch $ARGV[$i]\n"; } $i++; }

    The above will result in weird behaviour if you have a user named -l or a logfile named -u :-)))

      yeah the logfile name and the useraccounts name will always be the same. Infact it should test for the existance of them.
