rename_by_csv

This task allows you to rename a batch of files using a spreadsheet.

Using defaults:

Create a CSV named "rename.csv" with the columns "filename_old" (the exact matching current filename, not including directory) and "filename_new" (the new name you want, not including directory). Make sure it is UTF-8 (not from Excel).
Put your files into the "objects" folder.
Put your "rename.csv" into the root of this repository (i.e. same place as the Rakefile).
Open terminal and type rake rename_by_csv
Items included in the "rename.csv" will be copied, renamed, and output in the new folder "renamed/". (nothing will be deleted!)

The options can be changed by passing arguments with the rake command.

option	description	default value
csv_file	the filename of the CSV file used to rename	"rename.csv"
filename_current	the column name of the old filename	"filename_old"
filename_new	the column name of the new filename	"filename_new"
input_dir	the name of the folder containing the files to be renamed	"objects/"
output_dir	the name of the new folder to put the renamed files	"renamed/"

The order follows [:csv_file,:filename_current,:filename_new,:input_dir,:output_dir]. For example,

rake rename_by_csv["other_rename.csv","old_name","new_name","raw_folder","new_folder"]
