I am trying to use the example in #6 to read a file with pairs of machine names to do a diff. The list looks like this:
Here is the relevant code section for that:
cat /path/to/filename | while read -r aside bside
echo $aside >> localDiffList
echo $bside >> localDiffList
diff <(ssh root@$aside '/bin/cat /path/to/configfile') <(ssh root@$bside '/bin/cat //path/to/configfile') >> localDiffList
echo >> localDiffList
The problem seems to be that after it reads the first pair I guess it gets a return of 0 and then exits out. How can I get this to read all of the lines in the file? Thanks.
If anyone sees this then disregard. I found another solution.

* use <pre>...</pre> to insert a plain code snippet.
* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet.
For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
* use other HTML tags, such as, <b>, <i>, <blockquote>, <sup>, <sub> for text formatting.

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
