I am trying to find out if a program exists on Linux and I found this article. I tried executing this from my go program and it keeps giving me an error saying it can-not find "command" in my $PATH, which is to be expected since it's a built-in command in linux and not a binary. So my question is how to execute built in commands of linux from within go programs?

exec.Command("command", "-v", "foo")

error: exec: "command": executable file not found in $PATH

    Just like that article says, "command" is a shell built-in. You can do this natively in go via exec.LookPath.

    If you must, you can either use the system which binary, or you can execute command from within a shell,

    exec.Command("/bin/bash", "-c", "command -v foo")
