cli to track app utilizing CPU

[a s p a s i a]

Thank you both for your help.

I'd like to summarize the CLIs that I have used to
check the offending application:

1.  top

- press <M> [capital M]  - this sorts the
summarized memory util version in by memory usage.

2.  ps

type: ps -eo pid,vsz,rss,args --sort rss | more

where:
pid - process ID
vsz - virtual memory usage
rss - resident set size (physical RAM)
args - command args to display the processes

I am sorting it by physical RAM output.

....

free and `cat /proc/meminfo` - provides me a summary snapshot
of free and used memory related statistics; for my purpose
the ps CLI above allowed me to see in detail the offending application.

thanks again.

- a.
