[M. Tariq Ayub]

How can i cahnge password of diffreent user from command line in HP-UX 11i.

ie

passwd user1 password
passwd user2 password

Hi,

you have to be logged as root to change password of other users.
syntax is:
passwd user1
and system will ask you for new password

[lawrenzo]

procedure is -

su - root
passwd user
passwd -f user (force's the user to change passwd)

if your system is trusted you can reset the account and password by typing

/usr/lbin/modprpw -x user

I want to specify the new password from the command line. My system is not trusted. I need to cahnge 500 user password.

You should take a look at using Expect to script this.

There is really no other way that I know of via the shell to do this.

Hi,

If the users already exist then

#cat /etc/passwd |awk -F: '{print $1}' > file

for i in 'cat file'
do
passwd $i
done

[M. Tariq Ayub]

i want to provide the password by myself

Hello Tarik,

You can use this command, and note that even if /usr/sam/lbin/useradd.sam is a symbolic link to /usr/sbin/useradd, you cannot use this last command.

/usr/sam/lbin/useradd.sam -g users -d /home/username -c "comment of user" -s /usr/bin/ksh -p pass_of_user -o -u 104 user_name

Note the -p option, which with you can precise the password, but the problem is that exactely the word given will be saved on the passwd file (ie: not encrypted).

Hi,

Like Patrick say, you must use expect. With Expect you can 'convert' interactive command like passwd to 'automatic'.

Hi,

And make sure that if you script the "passwordchanger.ksh" you keep the script with passwords in a safe place with filepermissions that only root can see its content and change it.

The easist method is to use Perl. You can use the getpwent() function to read each entry, call the crypt() function to create the new passwd hash and then write the entry out to another file. When you are finished copy the new file to /etc/passwed and you are set.
