Clean-Up filenames created by Handbrake

 I wanted a script to help me rename files that Handbrake creates.

Issues

There are mainly 2 issues that I come across:

• Spaces that I want to replace with underscores
• Remove Unprintable characters
• I determined that these were ASCII characters 001-037 (in octal)
• ls -b directory_with_octal_chars_in_filename

Solution

Script (rename.sh)

#!/usr/bin/bash
directory=${1}
if [ -z ${directory} ] ; then
  echo "Requires a path"
  exit 1
fi

# replace spaces with underscore
find ${directory} -type f -name "* *" |
while read file; do
  mv "${file}" "${file// /_}"
done

# remove unprintable ASCII chars
find ${directory} -type f -name "*"[$'\001'-$'\037']"*" |
while read file; do
  new_file=$(echo "$file" | sed -e 's/[\o001-\o037]//g')
  mv "$file" "$new_file"
done

Permissions

chmod +x rename.sh

Usage

./rename.sh Directory_To_Rename_Files_In
