## Solution

Here are the different values that the `'s'`, `'stat'` and `'state'` output specifiers (header "STAT" or "S") will display to describe the state of a process, in the output of various `'ps'` commands:

**D** - uninterruptible sleep (usually IO)  
**R** - running or runnable (on run queue)  
**S** - interruptible sleep (waiting for an event to complete)  
**T** - stopped, either by a job control signal or because it is being traced  
**W** - paging (not valid since the 2.6.xx kernel)  
**X** - dead (should never be seen)  
**Z** - defunct ("zombie") process, terminated but not reaped by its parent
