VIPW(8) System Management Commands VIPW(8)
NAME
vipw, vigr - edit the password, group, shadow-password or shadow-group
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).
