Little trash script for use with OS X. Mimics Finder's behavior when deleting a file that has the same name as a file already present in the trash, with a bonus.

trash.sh

#!/bin/bash

for file in "$@"; do
	filename=$(basename "$file")
	extension="${filename##*.}"
	filename="${filename%.*}"

	dest="$HOME/.Trash/$filename.$extension"

	if [ -f "$dest" ]; then
		dest="$HOME/.Trash/$filename.$(date +%Y.%m.%d\ %H.%M.%S).$extension"
	fi

	mv "$file" "$dest"
done
