$lognam is the first field of shadow. Is that the right syntax for the sed command? It works when I issue the sed at the command line, but not in the script. Thanks.

If you truly have single qoutes round your sed prgramme, then your problem is that $test1 and $test2 are not getting expanded. Unsure how you got it to work from the command line as it should have had the same issue when issued manually. Since you have nothing in the quotes that requires single quotes, you should be able to replace them with double quotes:

Code:

sed "s/$test1/$test2/g" shadow > shadow.modified;

If that doesn't work, try echoing the command to verify that your variables are as you expect:

Code:

echo sed "s/$test1/$test2/g" shadow

lppasswd

lppasswd(1)							    Apple Inc.							       lppasswd(1)

NAME

       lppasswd - add, change, or delete digest passwords.

SYNOPSIS

       lppasswd [ username ]
       lppasswd -a [ -g groupname ] username
       lppasswd -x username

DESCRIPTION

       lppasswd  adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt
       for the old and new passwords.  When run by the super-user, lppasswd can add new accounts (-a username), change	existing  accounts  (user-
       name), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames.

OPTIONS

       lppasswd supports the following options:

       -g groupname
	    Specifies a group other than the default system group.

SECURITY ISSUES

       By  default,  the lppasswd program is not installed to allow ordinary users to change their passwords. To enable this, the lppasswd command
       must be made setuid to root with the command:
       chmod u+s lppasswd

       While every attempt has been made to make lppasswd secure against exploits that could grant super-user privileges  to  unprivileged  users,
       paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead.
