pwdadm

Have you read the command reference for the command?

pSeries and AIX Information Center

If you need further info please let us know which particular aspect of the command you do not understand.

thanks i got ... but some where i read tht pwdadm cmd is used to create user without passowrd. tht article gave eg as "pwdadm -c username"

man pwdadm

If you check my last post and follow the link provided, then click the "-c" link that is fairly obvious near the top of the linked page, where it says:

Syntax
pwdadm [ -R load_module] [  -f Flags |  -q | -c  ] User

you will see the -c option in detail and it says:

-c 	 Clears all password flags for the user.

Unless you can post your question or at least details of the "some where i read tht pwdadm cmd is used to create user without password" to clarify your problem then I don't think we can offer much more useful advice.
