PS looked at the state, found that the state is sl+,
In Linux, the status is as follows:
D non-disruptive uninterruptible sleep (usually IO)
R is running, or the process in the queue
S is in a dormant state
T stop or be traced
Z Zombie Process
W enters memory Exchange (invalid starting from kernel 2.6)
X dead Process
< high-priority
N Low Priority
L Some pages are locked into memory
s contains child processes
+ Group of processes in the background
L multi-threading, cloning threads
Based on the above information, it is known that sl+ is in hibernation, multithreading, and is a background process.
