subprocess

问题 I am executing curl command through subprocess. This curl command starts video processing at another server, and waits for the response. Once the process is done, the remote server returns json object. I am checking the status of the subprocess using poll() value, which is None - process not completed, 0- process completed successfully and 1- for error. I am getting the correct response if the processing takes around 30 mins/or less on remote server, but if the processing is taking more time,

问题 This is my code - import subprocess import sys HOST="xyz3511.uhc.com" # Ports are handled in ~/.ssh/config since we use OpenSSH COMMAND="uptime" ssh = subprocess.Popen(["ssh", "%s" % HOST, COMMAND], shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) result = ssh.stdout.readlines() if result == []: error = ssh.stderr.readlines() print (sys.stderr, "ERROR: %s" % error) else: print (result) and this is the error I'm getting- ERROR: [b"'ssh' is not recognized as an internal or external

问题 I would like to launch an ncurses based application from python using subprocess module. The ncurses based application is TABARI, an event extraction system. The result of event extraction is saved to a file. I would like to launch it from a python script, wait for it to terminate and then read the results file. A code sample is shown bellow: import subprocess proc = subprocess.Popen('TABARI -a ' + file, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) print proc.communicate() The

问题 Printing the output of a subprocess while saving the result is not a new problem, and has been answered many times before e.g.: https://stackoverflow.com/a/28319191/5506400 This does not work for me because I am trying to maintain the shell colours printed. E.g. when one goes systemctl status application , its prints running in green. The above-mentioned methods all rely on reading a line one by one from subprocess, but it seems to me by them the colour information is stripped off and lost. I

问题 I have this script: import subprocess p = subprocess.Popen(["myProgram.exe"], stdin=subprocess.PIPE, stdout=subprocess.PIPE) while True: out, _ = p.communicate(input().encode()) print(out.decode()) which works fine until the second input where I get: ValueError: Cannot send input after starting communication Is there a way to have multiple messages sent between the parent and child process in Windows ? [EDIT] I don't have access to the source code of myProgram.exe It is an interactive command

问题 I'm trying to make a python script that would clone(ISO image) one usb stick to another using dd if=/dev/sda of=/dev/sdb Here's my problem: I want to create progress bar showing what is done. I tried: Looking at storage space at second usb stick, but this doesn't work beacause ISO image scans also unused space By adding status=progress to dd command I can get progress in terminal but I can't figure how to access stdout from python. I tried subprocess.Popen,run(stdout = PIPE) with and without
