suppose if you wanna change password for kishore
< then it will promt you to enter new passwd then after it will prompt you retypepaswd
Below you can see its showing as only root can change .what does that mean ?
That mean only root can specify the username and delete . Suppose your trying to change the password for your userid you dont need specify the username . just change using passwd command as below .
Below you can see error " BAD PASSWORD: it is based on a dictionary word " . Does this really error ?
Answer is no . its just warning stating paswwd is not secure as you might gave regular names . Always try to use atleast 6-8 characters including lower/upper case with numeric number .
