Quick plan:
1. Create a vm file (for example shbat.vm) in your <xwiki directory>/templates/
folder, which contains this:
$response.setContentType('text/plain')
#set($filename = "${doc.name}.sh") ## or some other way of retrieving the
target filename, like $doc.display('scriptTitle') if it is in an object.
$response.setHeader('Content-Disposition', attachment; filename=$filename")
$doc.getRenderedContent ## if you have the script content in a wiki document, or
$doc.use('XWiki.YourScriptClassname')
$doc.display('scriptContentProperty')
## if the content is placed in an object of the XWiki.YourScriptClassname type
attached to your document, and the script content is placed in a TextArea
property named scriptContentProperty.
2. Create links to your document like:
[Download this script>${doc.fullName}?xpage=shbat]
