Recursively rename files to ASCII Standard

Question

So we have a problem where we need to crawl through hundreds of thousands of images and rename all of them to comply with ASCII standards. After doing a lot of research online,

Answer 1

Put this in a shell script, say fixname.sh:

#!/bin/sh

dir=$(dirname "$1")
name=$(basename "$1")

newname=$(echo "$name" | sed -e 's/[^A-Za-z0-9._-]/_/g')
if [ "$name" != "$newname" ]; then
    if [ ! -e "$newname" ]; then
        mv "$1" "$dir/$newname"
    else
        echo >&2 "$newname already exist for $1"
    fi
fi

Then use find like so:

find . -type f -exec sh fixname.sh {} \;
