Compute newest kernel version from Makefile on Torvalds' git repository

Get newest kernel version by parsing the most bleeding-edge Makefile possible. Useful for doing things like writing live ebuilds and/or self-updating PKGBUILDs for testing purposes.

Useful for CSV files. In the command, the file in question is comma delimited but contains double quoted fields containing commas and contains no @ symbols (as confirmed with http://www.commandlinefu.com/commands/view/9998/delimiter-hunting). This command converts the delimiting commas to @s while preserving the commas in the fields using the "uniqueString" to mark the ends of lines.
