Useful script to remove extra MacOS metadata files when moving files from MacOS to Linux. Also remove any Solidus characters (slash) from filenames which are allowed on Mac but not in Linux

MacOS-to-Linux-File-Cleanup.sh

#!/usr/bin/env bash

# Remove .DS_Store Files
find . -name ".DS_Store" -type f -delete

# Remove AppleDouble Files
find . -name '._*' -exec rm {} \;
find . -name ".AppleDouble" -type f -delete

# Change Any Illegal Solidus Chars in Filename to Fraction Slash
TARGET_CHAR=$(echo -ne '\xef\x80\xa2')
REPLACEMENT_CHAR="⁄"
find . -depth -name "*$TARGET_CHAR*" -print0 | while IFS= read -r -d '' file; do
	new_file=$(echo "$file" | sed "s/$TARGET_CHAR/$REPLACEMENT_CHAR/g")
	sudo mv "$file" "$new_file"; done
