23310 pts/3    Sl+    0:00 node index.js
23568 pts/1    T      0:00 sudo node index.js
23824 pts/4    S+     0:00 sudo node index.js
23826 pts/4    Sl+    0:00 node index.js

These are process STATE codes - from the man page

       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.
       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
       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

       For BSD formats and when the stat keyword is used, additional
       characters may be displayed:
       <    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

So what is the diff between S+ and S1+ ? – Antarus Jan 20 '14 at 12:45
@Antarus I believe its Sl+ and not S1+. Meaning its in interruptible sleep, foreground process group and multi-threaded. – Agent47DarkSoul Jan 28 '15 at 12:52
