Kill the process using its name inside linux (Python)

Question

this works, but it kills every Python process.

pkill python

However, I cannot do:

pkill myscript.py

I have also tried killall, but with no luck either. Do I have to user regular expressions?

By the way, I want to do this in a python script with import os.

Answer 1

Did you launch the Python subprocess from the same script you are killing it from? If so, see this question for details. If not, you can use pkill's -f option to search for the script name in the Python process's argument list, but you still run the risk of killing something you didn't intend to. See the man page for more info.
