How to view the memory occupied by a process under Linux

Linux to see the memory occupied by a process, the first can be found through the PS command process ID, such as PS -ef | grep Kafka can see the process ID of this program Kafka

　　

As you can see is 2913, you can now view the memory using the following command:

2913

　　

This allows you to see CPU and memory occupancy in real time, and then press Q to return to the command line

You can also use the PS command directly to view: PS -aux | grep Kafka

　　

The first dimension is CPU and memory occupancy, and the next 943100 is the amount of physical memory used, in K, at which time the Kafka consumes about 943M of memory

You can also view the status file for a process: cat /proc/2913/status

　　

The vmrss corresponds to the physical memory footprint, about 943M and just the same

You can also view memory consumption dynamically with the top command

By: ps aux | Sort -k4,4nr | Head - n -View the top 10 memory-consuming programs
