no chance to input passwd when create new user in loop

Hi Dears,

I have one script to create new users with information in one plain text file. This script will read all lines in the file and create one users for one line.

Sample file:
#action;login,full name title,expire date,project
+;gmwen,Bruce Wen QA,04/01/2012,BT
+;xxdeng,Shown Deng DEV,04/01/2012,BT
+;thli,Angela Li QA,04/01/2012,BT
+;xinhuang3,Jason Huang DEV,04/01/2012,BT

+ means to create.

After executing useradd command, I will set password for user with passwd command. Normally, it should prompt for password twice. But my script does not give me chance to enter password and just print below error to me:

HTML Code:

Changing password for user gmwen.
New UNIX password: BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password: Sorry, passwords do not match.
New UNIX password: BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password: New UNIX password: passwd: Authentication information cannot be recovered

In addition, subsequent users cannot be created because the script exits due to above error.

Bash version:
GNU bash, version 3.2.25(1)-release-(x86_64-redhat-linux-gnu)
on Red Hat 5.4

However, for bash version
GNU bash, version 3.00.16(1)-release-(sparc-sun-solaris2.10)
, it works well on Solaris OS.

Anybody can help me out of this trouble? Thanks!

LEARN ABOUT NETBSD

passwd

PASSWD(1)						    BSD General Commands Manual 						 PASSWD(1)

NAME

     passwd -- modify a user's password

SYNOPSIS

     passwd [user]
     passwd [-d files | -l] [user]
     passwd [-d nis | -y] [user]
     passwd [-d krb5 | -k] [principal]

DESCRIPTION

     passwd changes the user's password.  First, the user is prompted for their current password.  If the current password is correctly typed, a
     new password is requested.  The new password must be entered twice to avoid typing errors.

     The new password should be at least six characters long and not purely alphabetic.  Its total length must be less than _PASSWORD_LEN (cur-
     rently 128 characters).  Numbers, upper case letters and meta characters are encouraged.

     All options may not be available on all systems.

     -d database
	   This option specifies the password database that should be updated.	The following databases are supported:

	   files  This specifies that the password change should be applied to the local password file.  When changing only the local password,
		  passwd uses pwd_mkdb(8) to update the password databases.

	   nis	  This specifies that the password change should be applied to the NIS password database.  The rpc.yppasswdd(8) daemon should be
		  running on the master NIS server.

	   krb5   This specifies that the user's Kerberos 5 password should be changed.  The host must be configured to use Kerberos.  See
		  krb5.conf(5).

     -l    This is the equivalent of -d files.

     -y    This is the equivalent of -d nis.

     -k    This is the equivalent of -d krb5.

     If a password database is not specified, passwd will change the password database as determined by the Pluggable Authentication Module (PAM)
     library.

     The type of cipher used to encrypt the password depends on the configuration in passwd.conf(5).  It can be different for local and NIS pass-
     words.

FILES

     /etc/master.passwd  The user database
     /etc/passwd	 A Version 7 format password file
     /etc/passwd.XXXXXX  Temporary copy of the password file
