Story #4030

Updated by Peter Amstutz almost 6 years ago

Need a command line tool to provide comprehensive editing of collections/manifests:

* Delete files or streams
* Filter (include/exclude files by regex)
* Rename files or streams (by name or by regex)
* Combine manifests to get a new manifest
* Add file(s) from another collection
* Upload files using arvados.command.put module and add to collection
* Possibly optimize by re-packing small files (or files made up of many small ranges) into whole blocks

User should be able to specify whether to modify collection in place, create new collection, or operate on manifest text read in from stdin.
