Where is the code for "tee" in Mac OS?

Question

Where is the code for the terminal command 'tee' located in Mac OS?

[Added] Is it possible to read the exact code, that my mac is using (not the online codes)?

Answer 1

It's BSD, not Linux, code.

Answer 2

Answer 3

Here is the source code of Apple's unix:
http://developer.apple.com/Darwin/

If it is up-to-date this is the exact code that your mac uses.

Answer 4

By "code", I guess you mean source code, right? See there

EDIT: I see the question has been made more precise.

See exactly in the "plain" BSD code here as a Apple Developer login (free) is required to browse their code.

Answer 5

Do you mean, where is the executable? If that's what you're asking, it's at /usr/bin/tee. You can locate any command in your path by using the which utility. It will print out the full path to the command. For example:

$ which tee
/usr/bin/tee
$

If you're asking about the actual source code, a number of answers are already here that provide you with links to Apple's source code. The utilities themselves are split amongst a number of packages and there's no real index, so you'll have to browse the names and check packages that sound like they might contain the source for any given utility.
