lets see who remember last sem's CT's and end sem

write a script to add 50 users to ur machine without useradd command.
now delete these 50 users and thier all stuff without using userdel command

nice 2 see ankur u r taking active part in dis section............
and yes dis is a nice question and i hope 3rd cs-it guys w'll b posting d solution soon ............
and yes dis type of scripts we r going 2 ask u guys in tux wars and der will lot of unix knowlegde testing so b
preapred ..............
ankur ask ur friends also 2 take part in dis it seems u r only interested in unix................

its simply................
i=1;
j=505;
while [ $i -le 50 ] ; do
mkdir /home/user$i;
echo "user$i:x:$j:" >> /etc/group;
echo "user$i::$j:$j:user$i:/home/user$i:/bin/bash" >>/etc/passwd;
cp /etc/skel/.* /home/user$i;
let i=$i+1;
let j=$j+1;
done

ur program is absolutely correct but u missed out something .
Think nettech

yar u written d script correctoly but u have missed shadow file and password .........
u can use passwd command to give passwd to users and shadow file willbe automatically loaded with d value.............

and 1more thing nobodu has written for userdel try dat also...........

entry in shadow file ain't that important,user can login w/o password.
There's an important thing he missed out. Hint:u r in your home with hands tied

yaar it hit me... you have to give permissions to the user... correct me if wrong??

u got it beagle
the lines are:
chown -R user$i /home/user$i
chgrp -R user$i /home/user$i
chmod 700 /home/user$i

yeah...u r right...
but entry in shadow file is important..when we use 'x' in second field of passwd file......

otherwise.. it works without entry in shadow file also.....

ankur do u know user can login even if he has no entry in /etc/passwd file so problem is not just for login u have to manage its security also so use passwd caommand and provide a proper password 2 user .....

how can user login w/o having entry in /etc/passwd ?

dear ankur it seems u have not attended the workshop of unix
dis thing have been discuss in that workshop and u can ask to any one of freinds who have attented the workshop
and haan one more thing please take part in activities your seniors are oragnising that is for your benefits only
