# Rename TRACKNUMBER #
|
||||
# #
|
||||
# Rename all of the files in a folder based on track #
|
||||
# number metadata. Currently, there is only support for #
|
||||
# flac files with the `.flac` extention at the end of the #
|
||||
# name. #
|
||||
# #
|
||||
# Change History #
|
||||
# 03/11/2023 Out Of Ideas Original code. This is a #
|
||||
# template for creating new #
|
||||
# Bash shell script #
|
||||
# Add new history entries as #
|
||||
# needed. #
|
||||
# #
|
||||
# 02/01/2024 Out Of Ideas The program worked pretty #
|
||||
# well in the first test. One #
|
||||
# of the files was named #
|
||||
# incorrectly. The program #
|
||||
# only includes support for #
|
||||
# two-diget track numbers. A #
|
||||
# goal for the future, is to #
|
||||
# use a for loop instead of if #
|
||||
# statements to remove the #
|
||||
# limit of digits. It is a #
|
||||
# concern, that the script #
|
||||
# may malfunction with #
|
||||
# filenames that include #
|
||||
# special characters. If this #
|
||||
# is a problem, then instead #
|
||||
# of double-quotes, `print` #
|
||||
# will be used to escape #
|
||||
# special characters. Also so #
|
||||
# for, flac is the only #
|
||||
# filetype with support. More #
|
||||
# filetypes may be added in #
|
||||
# future versions. #
