这应该很简单,但我就是没找到方法。
如果我有一个进程ID,如何使用它来获取关于该进程的信息,比如进程名称。
/proc/<pid>/cmdline
包含命令行。ps -o cmd=<pid>
命令。 - Ricardo Stuven/proc/<pid>/comm
实际上提供了进程的名称。 - Skippy le Grand Gourou尝试使用PSUtil -> https://github.com/giampaolo/psutil
我记得在Windows和Unix上都可以运行良好。
针对Windows系统
一种获取计算机上所有程序进程ID的方法,无需下载任何模块:
import os
pids = []
a = os.popen("tasklist").readlines()
for x in a:
try:
pids.append(int(x[29:34]))
except:
pass
for each in pids:
print(each)
import os, sys, win32api
tasklistrl = os.popen("tasklist").readlines()
tasklistr = os.popen("tasklist").read()
print(tasklistr)
def kill(process):
process_exists_forsure = False
gotpid = False
for examine in tasklistrl:
if process == examine[0:len(process)]:
process_exists_forsure = True
if process_exists_forsure:
print("That process exists.")
else:
print("That process does not exist.")
raw_input()
sys.exit()
for getpid in tasklistrl:
if process == getpid[0:len(process)]:
pid = int(getpid[29:34])
gotpid = True
try:
handle = win32api.OpenProcess(1, False, pid)
win32api.TerminateProcess(handle, 0)
win32api.CloseHandle(handle)
print("Successfully killed process %s on pid %d." % (getpid[0:len(prompt)], pid))
except win32api.error as err:
print(err)
raw_input()
sys.exit()
if not gotpid:
print("Could not get process pid.")
raw_input()
sys.exit()
raw_input()
sys.exit()
prompt = raw_input("Which process would you like to kill? ")
kill(prompt)
这只是我结束进程的程序的复制粘贴,我可以让它变得更好,但现在已经可以了。
使用psutil,这是我能给你的最简单的代码:
import psutil
# The PID ID of the process needed
pid_id = 1216
# Informations of the Process with the PID ID
process_pid = psutil.Process(pid_id)
print(process_pid)
# Gives You PID ID, name and started date
# psutil.Process(pid=1216, name='ATKOSD2.exe', started='21:38:05')
# Name of the process
process_name = process_pid.name()
试试这个
def filter_non_printable(str):
ret=""
for c in str:
if ord(c) > 31 or ord(c) == 9:
ret += c
else:
ret += " "
return ret
#
# Get /proc/<cpu>/cmdline information
#
def pid_name(self, pid):
try:
with open(os.path.join('/proc/', pid, 'cmdline'), 'r') as pidfile:
return filter_non_printable(pidfile.readline())
except Exception:
pass
return
