Moving variable from file to program?

[solo2500]

I have a program written in python that passes a value to a variable in a file. I would like to pass that variable to another python program (of my own). My question is... How do I make the variable available to my python program and how do I print (echo) it? Below is what I invision.. but of course it doesn't work! ( I am a TOTAL novice!!!)
Thanks for any help!!!

file1.tmpl........................ to...................myprogram.sh
$current.outTemp ..................................#!/bin/bash
................................................................echo $current.outTemp

Simple files do not have variables, just content that is written to them.

You can write the content of a variable that is part of a Python script into a file where it will be held permanently.

You can subsequently read the contents of that file with another script and retrieve your content into a variable in the second script.

If this is not working for you it would be a good idea to post the contents of your scripts here, enclosed in [ Code ] markers by using the 5th button at the top of the message edit screen.

Yes... that's what I was trying to illustrate (admittedly very poorly!!!)
The file file1.tmpl contains $current.outTemp
The file myprogram.sh is a simple shell script to read and print the value of $current.outTemp.

myprogram.sh

Code: Select all

#!/bin/bash

echo $current.outTemp
 

I'm guessing at a minimum there needs to be a link (symbolic?) between the two files?

It might help if you showed the actual content of the file. I'm going to assume it is something like

Code: Select all

21.5

and you want to read the contents of that file into a variable in the script.

Code: Select all

#!/bin/bash
current_outTemp="$(cat file1.tmpl)"
echo $current_outTemp

A dot isn't valid in bash variable names, so I've used an underscore.
