I am trying to do a while do loop that asks for a password and returns if the password entered is incorrect. I have that part working however i want to modify it so that if a similar word is entered it will read "that is close but incorrect" and i cannot seem to get it working, being new in the linux. my code is simple:
Code:
read password
while [ "$password" != "hello" ]
do
echo "Wrong password, try again"
read password
done
Any help will be greatly appreciated.
Thanks.

yppasswd
yppasswd(1) General Commands Manual yppasswd(1)NAME
yppasswd - change password in Network Information Service (NIS)
SYNOPSIS
yppasswd [name]
DESCRIPTION
Note
If Enhanced Security is enabled on your system, use the passwd command to change your password, even if NIS is in use.
The yppasswd command lets you change your password in the Network Information Service (NIS) map, a network data base service. Only you or
the superuser can change your NIS password.
When you enter the yppasswd command, the program prompts you for the old password and then for the new password. Note that the passwords
are not displayed on the screen.
Next, the program asks you for the new password again, to verify that you have typed it correctly. If you do not type the passwords cor-
rectly, you will receive an error message after you enter the new password.
Your new NIS password must meet one of the following requirements: It must be a combination of at least six alphanumeric characters, or It
must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.
Note
The passwd command does not change the NIS password. This command only changes the local password file (/etc/passwd), and not the NIS mas-
ter password file.
ERRORS
Your new password does not meet the minimum length requirement. You misspelled your new password or its verification. Your new password
can not be activated. It must be different from your old password and your login name.
FILES
Password file NIS directory
