I am new to the Unix.
Can someone tell me what is the difference between 'PS' command and 'PS -aux"?
Isn't 'PS' mean the current running process?
Isn't 'PS -aux' mean the current running process too?
If they are the same, how come 'PS -aux' always has a lot more listing than 'PS'?
Thanks, (4 Replies)

Hi,
Can someone tell me what the difference is between ps -ef and ps aux. I was under the assumption that both commands would list ALL processes currently running on the system.
But on my server I find the following:
# ps
-ef | wc -l

# ps aux | wc -l

Hi I have a shell script I would like to run it has to run twice a day every 5 seconds for an hour I can do this with cron but I was hoping there was an easier way. Is there a way to make a process sleep only at a certain time of day say between 1 and 2 pm? Or under certain conditions?

DESCRIPTION
The machine-independent kcpuset subsystem provides support for dynamic processor sets. Conceptually kcpuset can be understood to be the ker-
nel equivalent of the user space cpuset(3) interface.
FUNCTIONS
kcpuset_create(retkcp, zero)
The kcpuset_create() function creates a dynamic CPU set and stores the result to retkcp. If the boolean zero is not false, the
allocated set is also initialized to zero.
kcpuset_destroy(kcp)
Destroys the CPU set kcp and schedules any linked CPU sets for deferred destruction.
kcpuset_copy(dkcp, skcp)
Copies the CPU set pointed by skcp to dkcp.
kcpuset_use(kcp)
Marks kcp as being in use by increasing the reference count of the object. Note that initially kcpuset_create() sets the reference
count to 1.
kcpuset_unuse(kcp, lst)
Decreases the internal reference count of kcp, and on the last reference (when the count reaches zero), destroys kcp. If lst is not
NULL, then instead of destroying, kcp will be added to the lst list for a deferred destruction.
kcpuset_copyin(ucp, kcp, len)
Copies the len bytes long user-space CPU set ucp to the kernel CPU set kcp.
kcpuset_copyout(kcp, ucp, len)
Copies the kernel CPU set kcp to the user-space CPU set ucp.
kcpuset_zero(kcp)
Clears the set kcp.
kcpuset_fill(kcp)
Fills the whole set kcp with ones.
kcpuset_set(kcp, cpu)
Adds cpu to the set kcp.
kcpuset_clear(kcp, cpu)
Removes cpu from the set kcp.
kcpuset_isset(kcp, cpu)
Returns 1 if cpu is part of the CPU set kcp.
kcpuset_iszero(kcp)
Returns true if the set kcp is empty.
kcpuset_match(kcp1, kcp2)
Compares the sets kcp1 and kcp2, returning true if these are identical.
kcpuset_merge(kcp1, kcp2)
Merges the set kcp2 to the set kcp1.
kcpuset_atomic_set(kcp, cpu)
The kcpuset_atomic_set() function operates as kcpuset_set(), but the operation is atomic; see atomic_ops(3) for more details.
kcpuset_atomic_clear(kcp, cpu)
Removes cpu from the CPU set kcp atomically.

The kcpuset subsystem is implemented within sys/kern/subr_kcpuset.c.
