Okay. That helps a lot. Just be sure to take a good look at what's inside the 'app1' group. You don't want people to be able to touch root's timestamps, etc. You may find a few users you you should specifically prevent them from running as.

Code:

# sudoers file

%app1 ALL=(%app1) NOPASSWD:  /path/to/update-time.sh

This would allow anyone in the app1 group to run /path/to/update-time.sh as any other user in the app1 group. Still no need to risk giving anyone root.

So:

Code:

#!/bin/sh

if [ "$#" -ne 2 ]
then
        echo "Usage:  $0 timestamp filename" >&2
        exit 1
fi

if ! [ -e "$2" ]
then
        echo "File $1 does not exist" >&2
        exit 1
fi

# Can also use 'stat' to get this on some systems
NEWUSER="$(ls -l "$1" | awk '{ print $3 }' )"

# If we are not the owner of the file, restart this script from the beginning
# as $NEWUSER via sudo.
[ "$USER" = "$NEWUSER" ] || exec sudo -u "$NEWUSER" "$0" "$@"

# Touch the file with an arbitrary timestamp.
touch -c -t "$1" "$2"

quota

quota(1M)						  System Administration Commands						 quota(1M)

NAME

       quota - display a user's ufs file system disk quota and usage

SYNOPSIS

       quota [-v] [username]

DESCRIPTION

       quota  displays	users'	ufs  disk usage and limits. Only the super-user may use the optional username argument to view the limits of other
       users.

       quota without options only display warnings about mounted file systems where usage is over quota. Remotely mounted file	systems  which	do
       not have quotas turned on are ignored.

       username can be the numeric UID of a user.

OPTIONS

       -v	Display user's quota on all mounted file systems where quotas exist.

USAGE

       See largefile(5) for the description of the behavior of quota when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

FILES

       /etc/mnttab     list of currently mounted filesystems

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       edquota(1M), quotaon(1M), quotacheck(1M), repquota(1M), rquotad(1M), attributes(5), largefile(5)

NOTES

       quota will also display quotas for NFS mounted ufs-based file systems if the  rquotad daemon is running.  See  rquotad(1M).

       quota may display entries for the same file system multiple times for multiple mount points. For example,

       quota -v user1
       may  display  identical quota information for user1 at the mount points /home/user1, /home/user2, and /home/user, if all three mount points
       are mounted from the same file system with quotas turned on.
