Function Documentation

main()

int main	(	int	argc,
		char **	argv
	)

Privileged executable that calls initgroups to refresh the secondary groups list. Comparable to sg, except that it doesn't update the primary group, and refreshes the entire list of secondary groups.

Necessary because Debian 13's sg no longer updates the secondary groups list.
