    did you saw a preview of your post before creating it?.
    see Markup in the Monastery

    the line around 91 is like this

    89:my $uid = getpwnam($user);
90:my $gid = getgrnam($user);
91:die "Cannot get uid for $user" unless ($uid);
92:die "Cannot get gid for $user" unless ($gid);

    IMO the user name you pass as argument has no relevant user id in the system.

      ya i did preview but i do not have any idea how to edit them.

      thanks for the link, now i have some idea to make my words look more neat. sorry about the format

      pertaining to my post, i just run as normal of what is the stated to run as a standalone i have no idea what is the user id?

      is it suppose to be my local host user id? if yes, i did tried but is the same result?

        AFAIK, In case if you are using *nix system, check with the command 'id <username>', if it gives some user id then your program also should work, otherwise check whether such user entry exist in /etc/passwd file, if not you may be using LDAP authentication.
