Several processes with the same name are running on host. What is the cross-platform way to get PIDs of those processes by name using python or jython?
pidof
but in python. (I don't have pidof
anyway.)/proc
because it might be unavailable (on HP-UX).os.popen('ps')
and parse the output because I think it is ugly (field sequence may be different in different OS).You can use psutil (https://github.com/giampaolo/psutil), which works on Windows and UNIX:
import psutil
PROCNAME = "python.exe"
for proc in psutil.process_iter():
if proc.name() == PROCNAME:
print(proc)
On my machine it prints:
<psutil.Process(pid=3881, name='python.exe') at 140192133873040>
EDIT 2017-04-27 - here's a more advanced utility function which checks the name against processes' name(), cmdline() and exe():
import os
import psutil
def find_procs_by_name(name):
"Return a list of processes matching 'name'."
assert name, name
ls = []
for p in psutil.process_iter():
name_, exe, cmdline = "", "", []
try:
name_ = p.name()
cmdline = p.cmdline()
exe = p.exe()
except (psutil.AccessDenied, psutil.ZombieProcess):
pass
except psutil.NoSuchProcess:
continue
if name == name_ or cmdline[0] == name or os.path.basename(exe) == name:
ls.append(p)
return ls
