如何在config.sh中将变量包含到a.sh和b.sh中？

Question

I've file config.sh:

data_dir=/home/olle/investing_data
bin_dir=/home/olle/investing_bin

I want to use $data_dir and $bin_dir in two separate scripts a.sh and b.sh .

How do I do it?

I tried this in a.sh and b.sh:

sh "config.sh"

But $data_dir and $bin_dir are empty.

I also tried this:

/bin/bash "config.sh"

Thanks for help.

You need to source the file, not execute it. In a.sh and b.sh :

. config.sh

or in bash , the more readable alternative

source config.sh
