OS X + Sed: “extra characters at the end of l command” Error

When executing the following command on OS X…


sed -i 's/megatron/pony/g' /path/to/file.txt

… the following error occurs:-


sed: 1: "/path/to/file.txt": extra characters at the end of l command

Unlike Ubuntu, OS X requires the extension to be explicitly specified. The workaround is to set an empty string:-


sed -i '' 's/megatron/pony/g' /path/to/file.txt

… and now, Megatron has transformed into a pony.

Thanks! That worked for FreeBSD 10.2.
