VIPW(8)

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

SYNOPSIS
vipw [-s]
vigr [-s]

DESCRIPTION
vipw and vigr will 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.
