In addition to monitoring, you can interact with the process list using various keyboard shortcuts, including:k –terminate a process. r –adjust the priority of a process. m –sort processes by memory usage. n – sort processes by PID. d –change the refresh time interval. h –see the...
Report systemwide memory usage summary. FILTER BY If none of these options are included, memory usage is reported for all processes, users, or mappings. (Note: If you are running as a non-root user, and if you are not using the --source options, then you will only see data from proc...
