Rename all files and directories for use with my janky bicycle mp3 player.

renusb.sh

#!/bin/bash

function rename_usb() {
    find . -type "$1" | while read -r file; do
        if [ "$file" -eq ".."
        newfile=$(echo "$file" | sed 's/[[:space:]]?/_/g
            #replace " - " with a single underscore.
            s/[[:space:]]-[[:space:]]/_/g 
            #replace spaces with underscores
            #replace "-" dashes with underscores.
            s/-?/_/g
            #remove exclamation points
            s/!//g
            #remove commas
            s/,//g')
        if [ -$1 "$newfile" ]; then
            echo "[WARNING] file exists: $newfile... Skipping."
        else
            echo mv "$file" "$newfile"
        fi
    done
}

# first rename all the directories
rename_usb 'd'

# then all the files
rename_usb 'f'
