Now a bit of explanation required for this command.Once you type the command it opens up an vi editor with an temporary file enlisting the password file information .So if you make an change it will not reflected in the passwd file until you save the file.The reason behind using this command over other way to view the password file in network environment is that it locks the password file when you start working with it.So no one can temper with it during that period.Once you are done(means you save the tmp file) ,it will release the lock associated with it.I think it's a better mechanism to view the sensitive data like passwd file.Never ever use other tool like cat, nano or any other means.
