vimball is a simple command-line tool for extracting vimball archives without using vim.
For extracting vimball archives use the following command:
vimball -x <vimball archive>
By default, vimball will try to choose a directory that is named similar to the vimball archive to extract the archive's files into. A specific directory name or path may also be selected using the following:
vimball -x <vimball archive> -C <extraction dir>
Listing the files contained inside the vimball archive is also supported using:
vimball -l <vimball archive>
