which where what?

Finding a binary in your $PATH can sometimes be confusing. Especially when which mybin and whereis mybin don’t find it, but command -v mybin does, and worse, your shell finds it- so what is wrong with which?

It has to do with how you define your path.

export PATH=~/bin/:$PATH

will work with bash and command -v, but which and whereis aren’t hip to shell metacharacters, and won’t pick up anything in ~/bin/. Solving this is pretty easy, too-

export PATH=$HOME/bin:$PATH
