You write your script to read it, that's how. Putting "how to use output from one bash script as input to another" into Google pulls up lots of solutions...have you tried that?
http://stackoverflow.com/questions/1...another-script
http://www.unix.com/shell-programmin...t-another.html

There are different ways to do it, depending on what the first script returns, and how. Also, you need to take into account that STDERR is different than STDOUT, and do you want to capture both, or just one?

Yeah, it will depend on what your first script outputs and what the second script wants to do.

In general, you can pipe the output of the first and 'read' it in second script. You can also use 'xargs' (check man page).

Simple:
Code:
#!/bin/bash

wget -O /tmp/fixed.txt http://match.fixing.cn/.hidden/winners/fixed.matches.txt

grep "Kempton Park" /tmp/fixed.txt | grep "4:30"
:D

Why don't you give us an example of what you are trying to do?

Spell out your words, please. And there are many bash scripting tutorials you can easily find...there is a link to one in my signature here. I gave you links with examples already in my first reply, and there is a sample script in post #5 that druuna provided. How many more examples would you like?
