how to pass variables between 2 bash scripts (export doesn't work)

here are 2 example scripts:
script.sh:

#!/bin/bash
export TEST=1

script2.sh:

#!/bin/bash
./script.sh
echo $TEST

script.sh is supposed to assign 1 to the TEST variable and script2.sh is supposed to run script.sh to assign 1 to the TEST variable and then print the value of the TEST variable (1).

that doesn't work for some reason. there is no output, and if I run script.sh and then run echo $TEST it won't print anything - the variable is empty or nonexistent.

any idea why/how to do that properly?

thanks in advance!

Script 2 is written as calling itself. Please correct any unintentional mistake – Chris Davies Feb 05 '21 at 20:43
@user414777 I accidentally put script2.sh as calling itself, thas not the case when I tested it. – Itai Nelken Feb 05 '21 at 20:51

Sub-processes cannot change environment variables or other stuff in their parent processes. You should source instead of running script.sh as a separate process: . ./script.sh. – Feb 05 '21 at 20:52
@user414777 that worked, thanks a lot. – Itai Nelken Feb 05 '21 at 20:55
