# Re-index files by changing the index suffix of file names.
# Usage: reindex_files <pattern> <offset>
# It renames all files in the folder following "pattern + number + extension" naming.
# <pattern> can be any regex (care not to match the index number).
# <number> is an integer ([0-9]+)
# It works for files with no extension as well.
# It will ask for confirmation before renaming the files.
