Config files in bash scripts?

Is there a good way to read and process a config file in a bash
script. I want global variables defined in a configuration file in
the form variable = value then read into the bash script.

Thanks,
John Brunsfeld

In the config file "file":

var1=val1
var2=val2
....

then do this:

. file

Hmmmmmm, so I just tried that
In a file name file:

var1=1
var2=2
var3=3

Then in a file called run.sh:

.. file
echo $var1
echo $var2
echo $var3

Output:
../run.sh: line 1: ????: command not found

Thanks,
JB

"file" is a command you're "dot-executing". Just like executing any
other command, "file" has to be in a directory in your PATH or you need
to specify an explicit path when you invoke it. Change run.sh to:

.. ./file
echo "$var1"
echo "$var2"
echo "$var3"
