Rebuild a Delimited File with a Unique Delimiter
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.
