I’m trying to combine a powershell Get-Content -Wait command with a simple python script like so:

Get-Content -Wait log_file.log | python app_that_reads_stdin.py

the trouble is, in my python script, sys.stdin never iterates. This behavior is not seen without the -Wait argument to Get-Content

the relevant python code is:

for line_number, message in enumerate(sys.stdin):
    # stuff

I expected each line written to the file after the Get-Content command was executed to be sent to stdout, where it could be read from stdin in python.

this all works fine with tail -f on *nux, and without the -Wait flag in powershell, so I’m fairly convinced this is a peculiarity of this powershell comandlet.

What am I doing wrong? Is there another way I can approximate tail -f on Windows?
