hello,
I have the list of users in my /etc/passwd and i being a super admin feel that some of the users need has to be deleted from the list.
Let's say these are following list of users ,
root:$1$FEoFUC9F$QL.JdIPi7Vt7hTsn9htej/:0:0:root:/root:/bin/bash
bin:*:1:1:bin:/bin:/bin/sh
daemon:*:2:2:daemon:/usr/sbin:/bin/sh
sys:*:3:3:sys:/dev:/bin/sh
adm:*:4:4:adm:/var/adm:/bin/sh
lp:*:5:7:lp:/var/spool/lpd:/bin/sh
sync:*:6:8:sync:/bin:/bin/sync
shutdown:*:7:9:shutdown:/sbin:/sbin/shutdown
halt:*:8:10:halt:/sbin:/sbin/halt
mail:*:9:11:mail:/var/mail:/bin/sh
news:*:10:12:news:/var/spool/news:/bin/sh
uucp:*:11:13:uucp:/var/spool/uucp:/bin/sh
operator:*:12:0
perator:/root:/bin/sh
games:*:13:60:games:/usr/games:/bin/sh
ftp:*:15:14:ftp:/var/ftp:/bin/sh
man:*:16:20:man:/var/cache/man:/bin/sh
www:*:17:18:www-data:/var/www:/bin/sh
sshd:*:18:19:sshd:/var/run/sshd:/bin/sh
proxy:*:19:21
roxy:/bin:/bin/sh
telnetd:*:20:22
roxy:/bin:/bin/sh
backup:*:34:34:backup:/var/backups:/bin/sh
ais:*:101:101:ais:/var/run/ais:/bin/sh
nobody:*:65534:65534:nobody:/nonexistent:/bin/sh
from the above list the only that seems valid to me is root, and i guess i can go and delete others...
So before me deleting those users, I just want to know what will be consequences for e.g if i userdel man , does that mean that man will not work...
Can someone explain me above the internals of adding users and deleting them, Is there a uid associated with it etc.. ?
Anyone please throw some light on this ???
