string comparison bug of bash on Ubuntu 9.04 i386

[Paul Gevers]

Hi Trulyliu,

Thank you for reporting bugs. However, this list is not the platform to
do that. Please report bugs in the bug-tracker at
https://bugs.launchpad.net/bugs/+filebug

And please, in your bug report try to give a more extensive description
of the problem, and also what you expect or what should happen.

By the way, it looks like you have your scripts mixed up. You report the
contents of run.sh, but use the extract.sh script (where we don't know
the contents of). Please be aware that usually scripts start with
#!/bin/sh, but in Ubuntu we replaced bash with dash for the sh
functionality, which might behave different in details.

With kind regards
Paul
