Convert python script which runs a bash script to executable file with Pyinstaller

Question

I want to convert a python script which runs a local bash script to executable file with Pyinstaller.

My project structure is as following:

Project/
|-- bash_script/
|   |-- script.sh
|-- main.py

The main.py contains a line which runs the script locally:

output = subprocess.check_output('./bash_script/script.sh', shell=True).decode()

Now, after converting the main.py to executable file in linux, if I run it on a different location from where main.py is located, it won't find the script.

I want to add the shell script to the python executable file, so it won't depend on the script locally, but, I will just have the executable file and it will eventually run.

I have tried using --add-data flag to pyinstaller converting commend, however it didn't work.

Thanks!

Note: I am using the following command:

pyinstaller --add-data "./bash_script/script.sh:." --onefile main.py

and I get an error after running in dist dir:

/bin/sh: 1: ./bash_script/script.sh: not found

According to serverfault.com/questions/319115/… you can pipe a bash script into bash via stdin. So you could embed the bash script as string in a Python script and feed it to bash. — Michael Butscher

@MichaelButscher I don't want to pipeline the result of the executable file, because eventually I want a single executable file which I can run from anywhere and still it will work. — Chopin

I meant you should use "subprocess" to run bash in a process and feed the script into bash's stdin. This has nothing to do with the stdin or stdout of your executable. — Michael Butscher

Oh ok, but how can I do that? because I am calling the bash script inside what I am trying to convert to executable file. Can you maybe elaborate on that? thanks! — Chopin

In your main.py:

import subprocess
import os

script = os.path.join(os.path.dirname(__file__),'bash_script','script.sh')
output = subprocess.check_output(script, shell=True).decode()
print(output)

Then run:

pyinstaller -F --add-data ./bash_script/script.sh:./bash_script main.py

And bobs your uncle!

p.s. -F is the same as --onefile
