[英]Get process name by PID
這應該很簡單,但我只是沒有看到它。
如果我有進程ID,我該如何使用它來獲取有關進程的信息,例如進程名稱。
在Linux下,您可以讀取proc文件系統。 文件/proc/<pid>/cmdline
包含命令行。
試試PSUtil - > https://github.com/giampaolo/psutil
我記得在Windows和Unix上運行良好。
對於Windows
無需下載任何模塊即可在計算機上獲取所有程序的方法:
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)
如果您只是想要一個程序或所有具有相同名稱的程序,並且您想要終止該過程或其他內容:
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)
這只是我的進程終止程序的粘貼我可以使它好多了但是沒關系。
使用psutil,這是我能給你的最簡單的代碼:
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()
嘗試這個
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
