Create an automatic routine to run several python script, using a shell script-CodePudding

I am trying to create a shell script that executes some python scripts in order. I have never done something like this and i don´t know if what i am doing is correct. Before executing the last file i need to activate an enviroment so it has the necesary imports to so it functions correctly. This is the script i have created (execute.sh):

#!/bin/sh
python path/file_1.py
python path/file_2.py
python path/file_3.py
# activate a virtual enviroment
source /path/env/bin/activate
python path/file_4.py

After this what sould I do? Just write this line in the terminal?

./execute.sh

CodePudding user response：

That should work. Usually I always do this when running a bash script with Python scripts inside.

#!/bin/bash

. /home/user/.bashrc # Load basic env as we're coming from cron

# Cd into our working directory in case we're not into it already
cd "$(dirname "$0")";

echo "----------------"
echo "Starting processing `date`"
echo "----------------"

conda activate models # Activate my conda environment

# Execute Python script
python script.py

if [[ $? = 0 ]]; then
    echo "Succesfull execution!"
else
    echo "Something wrong"
    exit 1
fi

This is in execute.run, which you then make executable chmod x executable.run, and run. This will work wherever you are because it will always try to cd into the directory where the script resides, so you can also call it from crontab.
