Top Forums UNIX for Dummies Questions & Answers Set sudo access to expire on given day\date? Post 302957129 by cjcox on Wednesday 7th of October 2015 10:41:49 AM

Somewhat flawed, but we use "at" and "usermod -G group-name user-name" to add a user to a group and "gpasswd -d user-name group-name" to remove. Two jobs, one to initiate, and one to end access and then as @frank_rizzo pointed out, we use a rule in sudo to allow access for that group-name.

newgrp

newgrp(1)						      General Commands Manual							 newgrp(1)

NAME

       newgrp -  change effective group ID sg - execute command with different group ID

SYNOPSIS

       newgrp [-l] [group]
       sg group -c command

DESCRIPTION

       The  newgrp  command changes the user's real and effetive group ID by replacing the current shell with a new shell. A new shell is launched
       even if an error occours.

       A password is requested if the group has a password and the user is not listed in the group file as being a member of that group. The pass-
       word can be changed with the gpasswd(1) command.

       If the new effective group ID is not in the supplementary group list, newgrp will add the new group ID to the supplementary list, too.

       With  no  operands  and options, newgrp changes the user's group IDs (real and effective) back to the group specified in password and group
       file.

       The sg command works like the newgrp command, except that it executes the given command with /bin/sh and upon exit the group ID of the cur-
       rent shell is not changed.

OPTIONS

       -l, --login
	      reinitialize the environment as if the user logged in.

       --help Print a help list.

       -u, --usage
	      Print a short usage message.

       -v, --version
	      Print program version.
