How to create a generic bash shell that will run whatever python is in the PATH?

Due to a complex corporate setup and having a venv I use in the CI pipelines and in the target deployment, I need the python inside my venv bin to run whatever python is in the PATH. I do the following but seems to end in an infinite loop:

This is the content of my $DEPLOYMENT_VENV/bin/python

#!bin/bash
python $@

the default actual python to use is setup in the PATH before.

Why would this lead to infinite loop or hanging forever?

There is an infinite loop if the python found by bash is the same than $DEPLOYMENT_VENV/bin/python.

There could be several reasons: the PATH variable does not have the same value in your terminal, than in the environment where the script is executed, etc.

To troubleshoot this, you should modify temporary the $DEPLOYMENT_VENV/bin/python, in order to add 2 lines to generate extra debug log message in a temporary file /tmp/dbg-python.txt:

#!/bin/bash
printf "DBG: " >>/tmp/dbg-python.txt 2>&1
type python >>/tmp/dbg-python.txt 2>&1
printf "\nDBG: PATH=%s\n" "${PATH}" >>/tmp/dbg-python.txt 2>&1
# python $@

Test again.

What is the content of the /tmp/dbg-python.txt file?
