grpunconv

Convert from shadow groups

$ sudo grpunconv

$ ls -la /etc/gshadow

grpunconv [options]

grpunconv converts from shadow group format back to traditional format. It moves password information from /etc/gshadow back to /etc/group and removes /etc/gshadow.
The tool reverses what grpconv does, returning to traditional group password storage. This is rarely needed on modern systems.

-R DIR

Chroot directory.

Display help information.

Requires root access. Reduces security. Rarely needed on modern systems.

grpunconv was developed as part of the shadow password suite to allow reverting shadow group changes.
