Read variables from text file to shell script

Question

I have a script and a file text containing variables for this script in the same directory. I need to read these variables but without this

. /path_to_my_file.file.txt

I don't want any paths inside my script.Doing this does not work

. file.txt

So what other possibilities i have?

Answer 1

See this question how to find out in which folder a script is: Unix shell script find out which directory the script file resides?

Afterwards, you can use this path to source your "config" file.
