vipw, vigr - edit the password, group, shadow-password or shadow-group file
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).
The options which apply to the vipw and vigr commands are: -g, --group Edit group database. -h, --help Display help message and exit. -p, --passwd Edit passwd database. -q, --quiet Quiet mode. -R, --root CHROOT_DIR Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory. -s, --shadow Edit shadow or gshadow database.
VISUAL Editor to be used. EDITOR Editor to be used if VISUAL is not set.
