Reading a conf file from a BASH script


Hi!

I'm a BASH newbie. I have to write a script for a project I'm working on, but I have no BASH book or manual.
Ok, this is my problem:
I want to read a config file I made myself. How do I make BASH read it and execute the commands in it? The file already contains a URL. Do I have to make another file or can I use the same as the URL's?

Hope this isn't a too stupid question

Start here:
http://www.tldp.org/LDP/abs/html/

As a hint:
Define a config file (config.txt) like this:
Code:
URL=http://test.com
NUM_TRIES=10
MSG=test it
Now, to use these values, put the folowing code in your script:
Code:
. config.txt
wget $URL

echo "not trying anything yet, I need to rite a loop for $NUM_TRIES tries"
echo $MSG
The first line here "sources" the config file.
That means that all varables declared in your config file are available in your script.

That's it,

Thanks a lot! The script now reads the config file without problems.

But I got a different problem now:

The script is supposed to download and unpack archives, but when it unpacks I get this error:
Code:
bzip2: Compressed file ends unexpectedly;
        perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
        Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Child returned status 2
tar: Error exit delayed from previous errors
How do I fix this one???

Soryy, but:
how am I supposed to know?
You did not post your script.
You did not describe what steps are taken.
You did not post the exact command with parameters that led to the error?
Do you Think I'm psychic? :-))

More info => More answers.

I resolved the unpacking problem. Everything is fine. The problem was that it saved at least 10 copies of the same file and then it couldn't unpack them correctly. Anyway you have been great help thank you a lot.

Hope to see you again
