Python: A small program, how to delete a group of processes, and only provide the program name without the pid.

We often use 'ps-e | grep name' or 'ps-e | awk'/name/{print $1} ''in shell to find the pid of a process, then, use 'sudo kill-8 XXX' to delete the process (we found that 'sudo killall name' cannot effectively Delete the process ). However, you may need to delete multiple processes and execute the preceding commands repeatedly. Bash can well complete the tasks of deleting processes in batches.
But here I want to discuss the solution in python. The subprocess module of python is used here.
 
1 #! /Usr/bin/env python
2
3 import OS
4 import sys
5 import getopt
6 import subprocess
7
8 def usage ():
9 print "killnames ..."
10 sys. exit (2)
11
12 def kill_names ():
13 try:
14 opts, args = getopt. getopt (sys. argv [1:], "")
15 TB t GetoptError, err:
16 usage ()
17
18 if not args:
19 print "Please input process name"
20 sys. exit (2)
21 # join List to string
22 myparam = "|". join (args)
23 # get the infos of working processes
24 myps = subprocess. Popen (["ps", "-e"], stdout = subprocess. PIPE, stderr = subprocess. PIPE)
25 # get List of pids
26 mypids = subprocess. popen (["awk", "/% s/{print $1}" % myparam], stdin = myps. stdout, stdout = subprocess. PIPE, stderr = subprocess. PIPE ). communicate () [0]. strip (). split ("\ n ")
27
28 for mypid in mypids:
29 OS. system ("sudo kill-8% s" % s mypid)
30
31
32 if _ name __= = '_ main __':
33 kill_names ()
