OSs .... if some body have script ot create user then please send me in mail i would really appreciate if some body helps me regding this issue.... and onemorething i would like to know "what are the other interactive capabilities included in 'C' when compare with 'Bourne Shell'" Thanq very much.... Zameer Ahmed Syed, Hyd-India. |
this has nothign whatsoever to do with netowrking, please pick your forum more carefully next time.
there are already commands to add users, e.g. useradd. what else do you wish to be able to do? and that second bit is just a bit of homework right? if so, please don't ask for help with it here. you need to research it yourself. |
thanx.............
|
sorry sir, In networking we are creating a user only one at a time my ambiton was creating no of users (how many i want using variables..... ) at a time just runnning one script.
thanq very much for u r reply... |
hi zameer,
if u want to add multiple users using only one command......then the desired command is "newuser". To use this command create a file and write the names of the users u wish to make in the format of /etc/passwd.I mean enter the entries in this file......let say "bulkusers" in the way that there are entries in /etc/passwd. tehn apply the command #newuser bulkuser see if it works......it worked in my case. best of luck |
Rabeea,
I create the file (just by typing the user names ) name 'user'.... and open the file passwd .... here i didn't get any thing (i am not able to understand ) what it is... look root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin sync:x:5:0:sync:/sbin:/bin/sync shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown halt:x:7:0:halt:/sbin:/sbin/halt mail:x:8:12:mail:/var/spool/mail:/sbin/nologin news:x:9:13:news:/etc/news: uucp:x:10:14:uucp:/var/spool/uucp:/sbin/nologin operator:x:11:0:operator:/root:/sbin/nologin games:x:12:100:games:/usr/games:/sbin/nologin gopher:x:13:30:gopher:/var/gopher:/sbin/nologin ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin nobody:x:99:99:Nobody:/:/sbin/nologin rpm:x:37:37::/var/lib/rpm:/bin/bash vcsa:x:69:69:virtual console memory owner:/dev:/sbin/nologin nscd:x:28:28:NSCD Daemon:/:/sbin/nologin sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin rpc:x:32:32:Portmapper RPC user:/:/sbin/nologin rpcuser:x:29:29:RPC Service User:/var/lib/nfs:/sbin/nologin nfsnobody:x:65534:65534:Anonymous NFS User:/var/lib/nfs:/sbin/nologin mailnull:x:47:47::/var/spool/mqueue:/sbin/nologin smmsp:x:51:51::/var/spool/mqueue:/sbin/nologin pcap:x:77:77::/var/arpwatch:/sbin/nologin apache:x:48:48:Apache:/var/www:/sbin/nologin squid:x:23:23::/var/spool/squid:/sbin/nologin webalizer:x:67:67:Webalizer:/var/www/html/usage:/sbin/nologin xfs:x:43:43:X Font Server:/etc/X11/fs:/sbin/nologin named:x:25:25:Named:/var/named:/sbin/nologin ntp:x:38:38::/etc/ntp:/sbin/nologin gdm:x:42:42::/var/gdm:/sbin/nologin amanda:x:33:6:Amanda user:/var/lib/amanda:/bin/bash canna:x:39:39:Canna Service User:/var/lib/canna:/sbin/nologin wnn:x:49:49:Wnn System Account:/home/wnn:/sbin/nologin fax:x:78:78:mgetty fax spool user:/var/spool/fax:/sbin/nologin netdump:x:34:34:Network Crash Dump user:/var/crash:/bin/bash nut:x:57:57:Network UPS Tools:/var/lib/ups:/bin/false ldap:x:55:55:LDAP User:/var/lib/ldap:/bin/false mysql:x:27:27:MySQL Server:/var/lib/mysql:/bin/bash ident:x:98:98:pident user:/:/sbin/nologin postfix:x:89:89::/var/spool/postfix:/sbin/nologin mailman:x:41:41:GNU Mailing List Manager:/var/mailman:/bin/false postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash privoxy:x:73:73::/etc/privoxy:/sbin/nologin pvm:x:24:24::/usr/share/pvm3:/bin/bash desktop:x:80:80:desktop:/var/lib/menu/kde:/sbin/nologin radvd:x:75:75:radvd user:/:/sbin/nologin zameer:x:500:500:zameer ahmed syed:/home/zameer:/bin/bash icm:x:501:501:icm_secbad:/home/icm:/bin/bash zameer123:x:502:502:zameer ahmed syed:/home/zameer123:/bin/sh zam123:x:503:502:duplicate of zameer:/home/zam123:/bin/sh icm123:x:504:503:company user:/home/icm123:/bin/bash zameer11:x:505:500:created for example:/home/zameer11:/bin/bash zameer111:x:506:500:just example:/home/zameer111:/bin/bash what's next.... |
hi zameer,
noe lets suppose ur file name is "bulkuser" and u want to enter a users named Zameer,Ali and Ahmed. now the syntax for writing in this file will be zameer:x:510:510:created forexample:/home/zameer:/bin/bash ali:x:511:511:created for example:/home/ali:/bin/bash ahmed:x:512:512:created for example:/home/ahmed:/bin/bash save and exit the file.After putting these entries run the command #newusers bulkuser |
just create the file using the joe or cat command . enter these entries and run the command.

hi, Rabeea.....
I follow u .... I create a file using and i done what ever u said .... after runnint the command newusers it says invalid line... why it was ... ThanQ Zameer Ahmed Syed... |
Rabeea,
should i use this line as first line #!/usr/bin/ |
yeah u can
if u cant run this command "newusers" then u can even write usr/bin/newuser.............hey .....do check whether it is newuser or newusers. |
Could anybody help me what i s the Problem.....
|
useradd is more common. personally i'd never recommend editing /etc/passwd directly.
|
still it gives me message like "Invalid line"......
|
well forget this silly script... you've still not been able to describe what you actually want to do... just try and run "useradd" as root. sometimes it might be adduser.
