You can get the pid of processes by name using pidof
through subprocess.check_output:
from subprocess import check_output def get_pid(name): return check_output(["pidof",name]) In [5]: get_pid("java") Out[5]: '23366n'
check_output(["pidof",name])
will run the command as "pidof process_name"
, If the return code was non-zero it raises a CalledProcessError.
To handle multiple entries and cast to ints:
from subprocess import check_output def get_pid(name): return map(int,check_output(["pidof",name]).split())
In [21]: get_pid(“chrome”)
Out[21]: [27698, 27678, 27665, 27649, 27540, 27530, 27517, 14884, 14719, 13849, 13708, 7713, 7310, 7291, 7217, 7208, 7204, 7189, 7180, 7175, 7166, 7151, 7138, 7127, 7117, 7114, 7107, 7095, 7091, 7087, 7083, 7073, 7065, 7056, 7048, 7028, 7011, 6997]
Or pas the -s
flag to get a single pid:
def get_pid(name): return int(check_output(["pidof","-s",name])) In [25]: get_pid("chrome") Out[25]: 27698
