Change files owner in debian package

I have a debian package with static files for a web application with root:root owner. After installing this package I need to change owner of all files for tomcat:tomcat, for example. I've read that this could be done by postinst script. However I don't how I can iterate over all files of package.

I think my script should look something like this:

#!/bin/sh    
set -e
USER="tomcat"

-- iterate over files    
    chown ${USER}:${USER} {current_file}
-- end iterate over files

I'll appreciate for any help.

Solution

  • Use the find command:

    find . -exec chown "${USER}:${USER}" {} +

    This will change the permissions recursively starting from the working directory.
