Hi all,
Is there a way to prevent users from being able to execute commands less a select few? For instance, I wish to allow the user to be only able to execute 1 command, which is exec a.sh. He should not be able to do simple stuff such as ls, cd, rm, cat, etc.
Can this be achieved?

pthread_setugid_np
PTHREAD_SETUGID_NP(2) BSD System Calls Manual PTHREAD_SETUGID_NP(2)NAME
pthread_setugid_np -- Set the per-thread userid and single groupid.
SYNOPSIS
#include <sys/types.h>
#include <sys/unistd.h>
int
pthread_setugid_np(uid_t uid, gid_t gid);
DESCRIPTION
pthread_setugid_np() changes the current thread's effective, real, and saved userid and groupid to the requested userid and groupid ( uid and
gid , respectively) and clears all other groupids.
uid can be the current real userid, KAUTH_UID_NONE, or, if the caller is privileged, any userid. gid can be the current real groupid or, if
the caller is priviledged, any single groupid.
Setting uid to KAUTH_UID_NONE means to "revert to the per process credential".
CAVEATS
Temporarily restoring root privileges for a non-privileged process is only possible on a per-process basis and not a per-thread basis.
pthread_setugid_np() is not intended as a privilege escalation mechanism.
Do not use pthread_setugid_np.2() in a security sensitive situation.
RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.
ERRORS
pthread_setugid_np() fails if one or more of the following are true:
[EPERM] The calling process does not have the correct credentials to set the override identity (i.e. The current credentials do
not imply "super-user").
[EPERM] If uid is set to KAUTH_UID_NONE, the current thread must already be assuming another identity in order to revert back.
[EPERM] The current thread cannot already be assuming another identity.
