Ps-a Show All current processes
Ps-ax shows no control of the terminal process
Ps-u better viewing the user better process
PS Aux|less filtering processes via CPU and memory
PS aux--sort-pcpu in ascending order based on CPU
PS aux--sort-pmem sorted in ascending order based on memory usage
Ps-aux--sort-pcpu,+pmem|head-n 10 synthesis to sort, showing top 10 results
Ps-c sshd Lookup sshd Process
Ps-f-C sshd View sshd detailed process information
Ps-l 1213 viewing threads for a particular process

Start: Process Start time
Time: When it was executed
Command: the command executed

1 ps aux--sory pcpu

#按CPU占用来排序

1 PS aux--sort-pmem 2 3 Memory occupancy rate sequencing

It's more practical to find out how it feels.
