我知道我可以像这样获得流程的stdin使用子流程python:
stdin
python
import subprocess f = subprocess.Popen('python example.py',stdin=subprocess.PIPE) f.stdin.write('some thing')
但我只想知道我想写入进程的pid,我该stdin 怎么做?
只需写信至/proc/PID/fd/1:
/proc/PID/fd/1
import os.path pid = os.getpid() # Replace your PID here - writing to your own process is boring with open(os.path.join('/proc', str(pid), 'fd', '1'), 'a') as stdin: stdin.write('Hello there\n')
