vipw, vigr - edit the password, group, shadow-password or shadow-group file

       The vipw and vigr commands edit 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).
