Most Unix systems no longer store the passwords in the password file; it is stored in a private file called /etc/shadow, only accessible by the root account. The passwords are stored in encrypted form in that file.
Passwords are hashed in linux, it's a one way conversion, you can't just view the password.
There are password finding programs, but they will take a long time to work and they are unlikely to show the real password used if the original password was well chosen.
Passwords are stored in hashed form in either /etc/password or /etc/shadow.
Typically passwords exist in /etc/shadow. They are encrypted and private to the administrator (root) account.
You can't recover passwords in Linux; you can only reset the passwords on various accounts.
There are no default passwords. Passwords are specified by the administrator at installation.
It is not possible for you to view passwords on a Mac using the Terminal.
/etc/passwd
Yes.
Under Settings>Security, you can check mark "Make passwords visible".
uname -a
you sure can if you have the password. otherwise. no
You can view the history of commands entered on a Linux system with the history command.

One common problem that is faced by Linux system administrators is not understanding permissions. Not backing up critical configuration files and not choosing good root passwords are other problems new Linux system administrators may face.
