Question

Does anyone know if there’s a way to run automatically in shell a list of commands (from a text file)?

I need to run a lot of scripts (around 1000). The scripts are in python and take 2 arguments each (dir_#, and sample#)

The text file I’ve made looks like this…

     python /home/name/scripts/get_info.py dir_1 sample1
     python /home/name/scripts/get_info.py dir_2 sample2
     python /home/name/scripts/get_info.py dir_3 sample3
     python /home/name/scripts/get_info.py dir_4 sample4
     ...

So, I would expect that passing this text file as argument to a command in terminal, could do the job automatically…

Thanks in advance,

peixe

Answer 1

That’s called a “shell script.”

Add this to the top of your file:

#!/bin/sh

Then execute this command:

chmod +x filename

Then execute it like a program:

./filename

Alternately, you can execute the shell directly, telling it to execute the commands in your file:

sh -e filename
