CQ5.5 Updating an existing package through CURL - aem

Question

I am using a series of CURL request to create my package.
What I am doing currently: I created a new package, added filters to it and then built the package.
Create package:
curl -f -N -u ${USER}:${PASS} -d "packageName=${PACKAGE}&groupName=${GROUP}" "${CMS_HOST}/crx/packmgr/service/exec.json?cmd=create"
Apply Filters:
curl -f -N -u ${USER}:${PASS} -F "path=/etc/packages/${GROUP}/${PACKAGE}.zip" -F "packageName=${PACKAGE}" -F "groupName=${GROUP}" -F "version=" -F "description=" -F "thumbnail=" -F "filter=${FILTER}" -F "_charset_=UTF-8" "${CMS_HOST}/crx/packmgr/update.jsp"
Build Package:
curl -f -N -u ${USER}:${PASS} -d "cmd=build" "${CMS_HOST}/crx/packmgr/service/script.html/etc/packages/${GROUP}/$PACKAGE.zip"
What I want to do: Add more filters to this package and build it again.
I am wondering if there is a way to update an existing package. I have been searching around to see how we can do this but have failed. Can someone please help me?
Thanks.
Update: Added the CURL commands I am using.

Answer 1

Here you go with an example where i have a package with two filters already
Going to add another filter
CURL for Create a Filter Node
curl --data jcr:primaryType=nt:unstructured --user admin:admin http://localhost:4502/etc/packages/my_packages/testcurl.zip/jcr:content/vlt:definition/filter/f2
Add the Filter properties
curl -u admin:admin -Froot="/content/geometrixx-outdoors/en/toolbar" http://localhost:4502/etc/packages/my_packages/testcurl.zip/jcr:content/vlt:definition/filter/f2.rw.html
IF required add additional properties (i.e. "mode" & "rules") for the Default package behaviour
curl -u admin:admin -Fmode="replace" http://localhost:4502/etc/packages/my_packages/testcurl.zip/jcr:content/vlt:definition/filter/f2.rw.html
curl -u admin:admin -Frules#TypeHint="String[]" -Frules=" " -Frules=" "http://localhost:4502/etc/packages/my_packages/testcurl.zip/jcr:content/vlt:definition/filter/f2.rw.html
Finally build your package to affect additional filter to add to your existing package
curl -u admin:admin -X POST http://localhost:4502/crx/packmgr/service/.json/etc/packages/my_packages/testcurl.zip?cmd=build

All the packages are stored under /etc/packages/my_packages path which can be modified by standard curl commands for node management. All packages have filters as sub-nodes.
All package manager commands are available via /crx/packmgr/service.jsp?cmd=help
For example, in order to build a package use /crx/packmgr/service.jsp?cmd=build
