PASSWD(5) File Formats and Configuration PASSWD(5)
NOM
passwd - fichier des mots de passe
DESCRIPTION
/etc/passwd contains one line for each user account, with seven fields
delimited by colons (« : »). These fields are:
• nom de connexion de l'utilisateur (« login »)
• un mot de passe chiffré optionnel
• l'identifiant numérique de l'utilisateur
• l'identifiant numérique du groupe de l'utilisateur
• le nom complet de l'utilisateur ou un champ de commentaires
• le répertoire personnel de l'utilisateur
• l'interpréteur de commandes de l'utilisateur (optionnel)
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.
The encrypted password field may be empty, 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.
A password field which starts with an exclamation mark means that the
password is locked. The remaining characters on the line represent the
password field before the password was locked.
Refer to crypt(3) for details on how this string is interpreted.
If the password field contains some string that is not a valid result
of crypt(3), for instance ! or *, the user will not be able to use a
unix password to log in (but the user may log in the system by other
means).
The comment field, also known as the gecos field, is used by various
system utilities, such as finger(1). The use of an ampersand here will
be replaced by the capitalised login name when the field is used or
displayed by such system utilities.
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.
