NOM
vipw, vigr - éditer les fichiers passwd, group, shadow ou gshadow
SYNOPSIS
vipw [options]
vigr [options]
DESCRIPTION
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).
OPTIONS
Les options applicables aux commandes vipw et vigr sont :
-g, --group
Éditer la base de données de groupes.
-h, --help

-p, --passwd

-q, --quiet
Mode silencieux.
-s, --shadow
Éditer les bases de données shadow ou gshadow.
CONFIGURATION
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.
