If I understand correctly, you are looking towards sourcing a file of variable assignments into your script?

For example, let's say we have a file "confRsync" containing the following...
Code:
var_1="value 1"
var_2="value 2"

Then, within our script, we can source these assignments into the current environment...
Code:
#!/bin/sh

. /path/to/confRsync

echo "$var_1"
echo "$var_2"

The script will produce the output
Code:
$ ./makeRsyn.sh
value 1
value 2

Cheers
ZB
