Running a python script from shell

Question

I want to run a python script from a shell script. I have been able to run it from the "command window" (Cygwin), but now I want to be able to call it from a shell script. It does not work the way I thought it would and the Internet has not really helped me with it.

My code so far:

#!/bin/bash
python Calibrate.py

I hope someone could help me further. Calibrate just contains a few basic command lines to transform some data that has been read in with an excelreader in the script itself.

Answer 1

Just make sure the python executable is in your PATH environment variable, then add in your script

In the file job.sh,

#!/bin/sh python <path/to/python/script>/python_script.py

Execute this command to make the script runnable for you : chmod u+x job.sh Run it : ./job.sh

Answer 2

A Bash script needs to use the Unix EOL (End Of Line) convention, which terminates each line with \\n . But it looks like your test.sh shell script file uses the Windows / DOS EOL convention, which terminates each line with \\r\\n .

You need to get rid of those \\r characters in test.sh, and you need to set your editor to use Unix line endings.

A simple way to strip \\r out of a file is to use the Unix sed command; I assume it's available in Cygwin:

sed -i 's/\r//g' test.sh

This removes all \\r characters in test.sh, writing the result back to test.sh
