Running Subsequent Scripts¶

Case I: Run Script 1, Wait, Run Script 2¶

For this, we want to wait for [script1.py](http://script1.py) to finish successfully, then we run script2.py.

#!/usr/bin/env bash
python script1.py && 
python script2.py

Case II: Run Script 1, Wait, Run Script 2 IFF Script 1 has failed¶

This is the case where we want to run [script2.py](http://script2.py) but IFF [script1.py](http://script1.py) has finished

#!/usr/bin/env bash
python script1.py || python script2.py

Case III: Run script1 AND script 2¶

We want to run both scripts concurrently as background processes

#!/usr/bin/env bash
python script1.py & 
python script2.py

Bonus Stuff¶

Wait Command¶

You can manually force the code to wait for all background processes to finish in the script before proceeding forward. This will continue even if there is a failure. It's very similar to the || command. There isn't a real difference.

wait

Permissions¶

So once you have a bash script .sh, make sure you have the permissions otherwise you won't be able to execute it. Just run this command

chmod +x <filename>

Now you can run the script.

./ <filename>
