Top Forums Shell Programming and Scripting Creating User Accounts from a list in file Post 93671 by mahendramahendr on Wednesday 21st of December 2005 08:25:38 AM

printf "Please enter var : "
read var

while (( ${#var} < 6 ))
do
print "$var value is less than 6"
printf "Please reenter var : "
read var
done

Regarding the first question :

if you have many users to add, take any one line of a user from /etc/paswd and format your user file with the same format.. after formating it, copy all the lines from the file and append it to /etc/passwd file in the end through vi and save.

You need to login as root first.

I'm not sure whether they is any other easy way, i generally add user ids in /etc/passwd. I also don't think we can assign the password, we need to run passwd command for each and every user.

Once you complete adding to /etc/passwd, run pwconv command.

Someone can help, if there is a simple way of doing it.

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
