I am publishing content from a Drupal CMS to static HTML pages on another domain, hosted on a second server. Building the HTML files was simple (using PHP/MySQL to write the files).

I have a list of images referenced in my HTML, all of which exist below the /userfiles/ directory.

cat *.html | grep -oE [^\'\"]+userfiles[\/.*]*/[^\'\"] | sort | uniq

Which produces a list of files

http://my.server.com/userfiles/Another%20User1.jpg
http://my.server.com/userfiles/image/image%201.jpg
...

My next step is to copy these images across to the second server and translate the tags in the html files.

I understand that sed is probably the tool I would need. E.g.:

sed 's/[^"]\+userfiles[\/image]\?\/\([^"]\+\)/\/images\/\1/g'

Should change http://my.server.com/userfiles/Another%20User1.jpg to /images/Another%20User1.jpg, but I cannot work out exactly how I would use the script. I.e. can I use it to update the files in place or do I need to juggle temporary files, etc. Then how can I ensure that the files are moved to the correct location on the second server
