Thank you, but probably i have to become more outspoken on this: we have a rule in place against using "leet speak" and the likes. If you expect me to put in the necessary effort to come up with a concise and correct answer i suppose i can expect you to put in the necessary effort not to save on a keystroke or two in return, yes? Please take into account that the people here are not freaks but hard working professionals. We maintain a professional tone here and expect others to do the same. Thank you for your consideration.

If you have to check for more than one condition just add these in your loop:

Code:
typeset -i continue=1

print - "waiting for all conditions to become false...."
while [ $continue -gt 0 ] ; do
     sleep 1
     (( continue = 0 ))
     if [ <condition1> ] ; then
          (( continue = 1 ))
     fi
     if [ <condition2> ] ; then
          (( continue = 1 ))
     fi
     if [ <condition3> ] ; then
          (( continue = 1 ))
     fi
     [...]
done
print - "all conditions turned false ...."


In your case you can check the condition of a certain keyphrase being in a file or not using grep.

I hope this helps.

wait_event_interruptible_exclusive_locked_irq

WAIT_EVENT_INTERRUPT(9) 					   Driver Basics					   WAIT_EVENT_INTERRUPT(9)

NAME

       wait_event_interruptible_exclusive_locked_irq - sleep until a condition gets true

SYNOPSIS

       wait_event_interruptible_exclusive_locked_irq(wq, condition);

ARGUMENTS

       wq
	   the waitqueue to wait on

       condition
	   a C expression for the event to wait for

DESCRIPTION

       The process is put to sleep (TASK_INTERRUPTIBLE) until the condition evaluates to true or a signal is received. The condition is checked
       each time the waitqueue wq is woken up.

       It must be called with wq.lock being held. This spinlock is unlocked while sleeping but condition testing is done while lock is held and
       when this macro exits the lock is held.

       The lock is locked/unlocked using spin_lock_irq/spin_unlock_irq functions which must match the way they are locked/unlocked outside of this
       macro.

       The process is put on the wait queue with an WQ_FLAG_EXCLUSIVE flag set thus when other process waits process on the list if this process
       is awaken further processes are not considered.

       wake_up_locked has to be called after changing any variable that could change the result of the wait condition.

       The function will return -ERESTARTSYS if it was interrupted by a signal and 0 if condition evaluated to true.
