There's a mistake in that script (I missed a curly bracket in the system()
call). This is the fixed version:
#!/usr/bin/perl
use strict;
my $passwd = "/tmp/passwd";
my $shadow = "/tmp/shadow";
my $start_uid = 200;
open(PASSWD, $passwd) || die "Can't open $passwd: $!";
open(SHADOW, $shadow) || die "Can't open $shadow: $!";
my @users;
PASSWD: while(<PASSWD>) {
my @passwd = split(/:/, $_);
my $user = $passwd[0];
my $uid = $passwd[2];
while (<SHADOW>) {
my @shadow = split(/:/, $_);
if ($shadow[0] eq $user) {
my $crypt = $shadow[1];
push(@users, { user => $user, uid=>$uid, crypt=>$crypt});
next PASSWD;
}
}
}
foreach my $user (@users) {
if ($user->{uid} >= $start_uid) {
print "useradd $user->{user} -p $user->{crypt}\n";
system("useradd $user->{user} -p $user->{crypt}");
}
}
