how to get value of variable config in bash? [duplicate]

Question

I have a linux config file with with format like this:

VARIABLE=5753
VARIABLE2=""
....

How would I get f.e. value of VARIABLE2 using standard linux tools or regular expressions? (I need to parse directory path from file). Thanks in advance.

Answer 1

You could use the source (a.k.a. .) command to load all of the variables in the file into the current shell:

$ source myfile.config

Now you have access to the values of the variables defined inside the file:

$ echo $VARIABLE
5753
