       vipw, vigr - éditer les fichiers passwd, group, shadow ou gshadow


       vipw [options]

       vigr [options]


       The vipw and vigr commands edits the files /etc/passwd and /etc/group,
       respectively. With the -s flag, they will edit the shadow versions of
       those files, /etc/shadow and /etc/gshadow, respectively. The programs
       will set the appropriate locks to prevent file corruption. When looking
       for an editor, the programs will first try the environment variable
       $VISUAL, then the environment variable $EDITOR, and finally the default
       editor, vi(1).


       Les options applicables aux commandes vipw et vigr sont :

       -g, --group
           Éditer la base de données de groupes.

       -h, --help
           Afficher un message d´aide et quitter.

       -p, --passwd
           Éditer la base de données de mots de passe.

       -q, --quiet
           Mode silencieux.

       -s, --shadow
           Éditer les bases de données shadow ou gshadow.


       The following configuration variables in /etc/login.defs change the
       behavior of this tool:

       MAX_MEMBERS_PER_GROUP (number)
           Maximum members per group entry. When the maximum is reached, a new
           group entry (line) is started in /etc/group (with the same name,
           same password, and same GID).

           The default value is 0, meaning that there are no limits in the
           number of members in a group.

           This feature (split group) permits to limit the length of lines in
           the group file. This is useful to make sure that lines for NIS
           groups are not larger than 1024 characters.

           If you need to enforce such limit, you can use 25.

           Note: split groups may not be supported by all tools (even in the
           Shadow toolsuite. You should not use this variable unless you
           really need it.
