NAZWA
       passwd - the password file

OPIS
       /etc/passwd contains one line for each user account, with seven fields
       delimited by colons („:”). These fields are:

       •   login name

       •   optional encrypted password

       •   numerical user ID

       •   numerical group ID

       •   user name or comment field

       •   user home directory

       •   optional user command interpreter

       The encrypted password field may be blank, in which case no password is
       required to authenticate as the specified login name. However, some
       applications which read the /etc/passwd file may decide not to permit any
       access at all if the password field is blank. If the password field is a
       lower-case „x”, then the encrypted password is actually stored in the
       shadow(5) file instead; there must be a corresponding line in the
       /etc/shadow file, or else the user account is invalid. If the password
       field is any other string, then it will be treated as an encrypted
       password, as specified by crypt(3).

       The comment field is used by various system utilities, such as finger(1).

       The home directory field provides the name of the initial working
       directory. The login program uses this information to set the value of
       the $HOME environmental variable.

       The command interpreter field provides the name of the user's command
       language interpreter, or the name of the initial program to execute. The
       login program uses this information to set the value of the $SHELL
       environmental variable. If this field is empty, it defaults to the value
       /bin/sh.
