    # PROCESS STATE CODES
    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.
    CODE | Meaning
    --- | ---
    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.

    For BSD formats and when the stat keyword is used, additional characters may be displayed:
    CODE | Meaning
    --- | ---
    < | high-priority (not nice to other users)
    N | low-priority (nice to other users)
    L | has pages locked into memory (for real-time and custom IO)
    s | is a session leader
    l | is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
    + | is in the foreground process group
