Pythonspot, subprocess.popen, call, and check_outputĪuthor Fabian Posted on SeptemSeptemCategories Python Tags async, blocking, exec, live, poll, popen, process, python, real, subprocess, time Post navigation However using poll, you get the ouput in real-time.Įndpoint, realtime output from subprocess You then get an example of how municate() does not show the output until the subprocess is complete. runProcessWithLiveOutput.pyĮxecute which commmand : Download this into the same directory as the Bash loopWithSleep.sh as an example program. # Poll process.stdout to show stdout liveįor an example that pulls all this together, see my runProcessWithLiveOutput.py on github. Process = subprocess.Popen(shlex.split(command),shell=False,stdout=process.PIPE) However if you use subprocess.Popen along with Popen.poll() to check for new output, then you see a live view of the stdout. If you start a process using process.call() or process.check_output(), then you cannot get the output until the process is compete.

Below is the full script: #!/bin/bashĮvery second it displays a line of output and takes a total of 5 seconds to run. This is a better end-user experience for longer running jobs.Īs an example of a long running command, consider the Bash script loopWithSleep.sh which I’ve uploaded to github.

In this article I will show how to invoke a process from Python and show stdout live without waiting for the process to complete. Using subprocess.Popen, subprocess.call, or subprocess.check_output will all invoke a process using Python, but if you want live output coming from stdout you need use subprocess.Popen in tandem with the Popen.poll method.
