[CentOS] Add instantly active local user accounts *with* password using useradd -p option ?
Hi, I need to setup a load of user accounts on a series of machines, for testing purposes. I'm using a script to do this, but the only problem I have so far: I have to activate them all manually by doing passwd user1, passwd user2, passwd user3, etcetera. The useradd man page mentions a -p option to define a password, but I can't seem to get this to work. Here's what I'd like to be able to do: # useradd -c "Gaston Lagaffe" -p abc123 -m glagaffe And put that line in a script, so the account is *instantly* activated. I tried it, but to no avail. Looks like there's some burning loop I have to jump through first :o) No security considerations here for the moment, since it's for testing. Any idea how this works? Niki

Rather try making a script which you can feed the user pass and other info. You can set password from shell like this: echo 123abc|passwd --stdin username

You can wrap this in a loop and feed it a list of names for the accounts that you need to create. The script is: PWD=`mkpasswd -l 8 -s 2`; export PWD echo "user = $1 password = $PWD" /usr/sbin/useradd -c "$2" -m -k /home/skeleton -n -p $PWD $1 echo $PWD| passwd --stdin $1 You can of course vary the parameters for password generation by changing the length (-l) and allowing special characters etc. The directory /home/skeleton contains all the files that you need to set up in each user's account. This can also be a customized .bashrc to set environmental variables etc. The line with the echo command is there so that you have a record of the password generated for each user. Hope this helps ChrisG

IIRC, the -p expects tha *encrypted password, as might be found in /etc/shadow. The --stdin others suggest should do it.> <snip>-- Bill
