There seem to be literally dozens of solutions to do read-only operations but very few to enable comfortable editing of the files in-place in a Unix / command line environment. Seems like a real gap in the software ecosystem atm: - fast - no limit on file size - spreadsheet style layout - command line - easily edit and update individual cell => save I've tried VIM's CSV plugins many times and have never been satisfied.
