What should we call the CLI tool?

There's been a few people bring up the idea of getting rid of the .php extension from our CLI tool, currently called ci.php. However, there's an existing Linux command, ci so I don't want to simply rename it to that. having a good idea coming up with a better name for it, however, so help a brother out - what's your idea for our CLI tool name?

why changing the name? it is a php file and should be called php.
