Kill process by name?
...
Assuming you're on a Unix-like platform (so that ps -A exists),

How to see top processes sorted by actual memory usage?
... for a little while: "unused memory is wasted memory". The Linux kernel keeps around huge amounts of file metadata and files that were requested, until something that looks more important pushes that data out. It's why you can run:
find /home -type f -name '*.mp3'
find /home -type f -name '*.aac'

What is RSS and VSZ in Linux memory management
... time, you could see RSS going up and VSZ staying the same.
There is also PSS (proportional set size). This is a newer measure which tracks the shared memory as a proportion used by the current process. So if there were two processes using the same shared library from before:
PSS: 400K + (1000K/...

echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
