[Help-bash] Help some problem in my Bash

[Budi]

I've used where command several times but just now typed it ...
$ where grep
-bash: where: command not found

What's my mistake that's spoiling my own bash ?
sincee help is really hoped and thanked... Thansk in advance

Try "whereis bash"? Or "which bash"?

You may have meant `whereis'. But `type grep' is a better way to accomplish
what you want.
