Introducing pfexec, a Convenient Utility in the OpenSolaris OS
Passwordless pfexec is the OpenSolaris version of Linux's sudo. Learn how to assign the appropriate rights profile to users so that they can execute commands with root privileges by prepending pfexec to the commands without becoming root.

Hi,
I have a doubt in introducing a delay in the programs.
We know that we do have a sleep() function/api using which
we can bring a delay in terms of seconds.
A minimum delay can be atleast 1 second.
Now I'm bothered about how to introduce a delay that is just
less than a second. Like... (3 Replies)
pfexec(1) User Commands pfexec(1)NAME
pfexec, pfsh, pfcsh, pfksh - execute a command in a profile
SYNOPSIS
/usr/bin/pfexec command
/usr/bin/pfexec -P privspec command [ arg ...]
/usr/bin/pfsh [ options ] [ argument ...]
/usr/bin/pfcsh [ options ] [ argument ...]
/usr/bin/pfksh [ options ] [ argument ...]
DESCRIPTION
The pfexec program is used to execute commands with the attributes specified by the user's profiles in the exec_attr(4) database. It is
invoked by the profile shells, pfsh, pfcsh, and pfksh which are linked to the Bourne shell, C shell, and Korn shell, respectively.
Profiles are searched in the order specified in the user's entry in the user_attr(4) database. If the same command appears in more than one
profile, the profile shell uses the first matching entry.
The second form, pfexec -P privspec, allows a user to obtain the additional privileges awarded to the user's profiles in prof_attr(4). The
privileges specification on the commands line is parsed using priv_str_to_set(3C). The resulting privileges are intersected with the union
of the privileges specified using the "privs" keyword in prof_attr(4) for all the user's profiles and added to the inheritable set before
executing the command.
USAGE
pfexec is used to execute commands with predefined process attributes, such as specific user or group IDs.
Refer to the sh(1), csh(1), and ksh(1) man pages for complete usage descriptions of the profile shells.
EXAMPLES
Example 1: Obtaining additional user privileges
example% pfexec -P all chown user file
This command runs chown user file with all privileges assigned to the current user, not necessarily all privileges.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
