I have this script that I am currently running that works great for all instances but one:

 #!/bin/sh
 pdfopt test.pdf test.opt.pdf &>/dev/null
 pdf2swf test.opt.pdf test.swf
 [ "$?" -ne 0 ] && exit 2

More lines to execute follow the above code ...

How would I go about changing this script to run "pdf2swf test.pdf test.swf" if "pdf2swf test.opt.pdf test.swf" fails? If the second attempt fails, then I would "exit 2".

Thanks
