Tips 1:
If you want to reset a password for a account normally you will use "#passwd" command. But it will ask to retype the password again. If you want to disable that "retype password" option then use the below command,
#echo "password"| passwd userid
If you use the above command then it wont ask you to enter the password second time.
Tips 2:
Whats is the difference between the below 2 command ?
#passwd userid and /usr/sbin/passwd userid
Answer :
If you use the #passwd userid - once u done the password reset using this command, then if you try to change the password again within a day , You will get the message like "Recently you have changed the password, you cant change the password again, try after few days"
But if you use the command #/usr/sbin/passwd userid - then it will allow you to change the password. This is the difference between direct #passwd command and #/usr/sbin/passwd command.
/usr/sbin/passwd - means this will give super user power. So it will allow to change the user id ,even if you changed 5 minutes before also.
