i have being task to create 100 users... i am able to create the user login name.. but now i have to create the password for these accounts... the solution i found on this forums does not seems to solve my problem... could some one help me??

my script is

Code:

for((i=0; i<=100; i++))
do
useradd -m user$i -u 180$i -g Admin -d /home/user$i -s /bin/sh -c 'User'$i

you can use chpasswd to change passwords in bulk.

sorry can i ask how do i use this command inside the script???

i want the whole process to be fully automated.. the user should not be ask to enter anything...
thanks in advance...

well you'd just insert it after the useradd command.

sorry i think my question is not clear or there is a misunderstanding...
can i know the command structure??? cos by putting chpasswd still require the user to input the username and password... what i need is that the user or administrator do not need to enter anything.. he only need to run the script....

In [1] you can read how pipes can be used efficiently. Then this should be easy:

Code:

echo username:password |chpasswd

You can also pipe a list of login data. Each line should include a username and password seperated by a colon.

just to confirm.. the full code will be as follow

Code:

for((i=0; i<=100; i++))
do
useradd -m user$i -u 180$i -g Admin -d /home/user$i -s /bin/sh -c 'User'$i
echo user$i:pass$i |chpasswd
done
