file

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).
