whats the difference between executing script like

# ./test

and

# . ./test 

test is simple script for example

export ALIAS="angelique"

./foo executed foo if it’s marked as executable and has a proper shebang line (or is an ELF binary). It will be executed in a new process.

. ./foo or . foo loads the script in the current shell. It is equal to source foo

With your example code you need to use the second way if you want the exported variables to be available in your shell.
