Linux查找命令源代码

Question

When I type find into my terminal, this is the output I get:

My-MacBook-Air:desktop User$ find
usage: find [-H | -L | -P] [-EXdsx] [-f path] path ... [expression]
       find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]

How does my computer know where the source code for this command is and how can I access it myself?

Ok well ... first this is probably not Linux but MacOS? But no matter what, your computer doesn't use any source code but a compiled executable, that is located somewhere in your search path -- a list of directories that are searched when you enter a command, typically something like /usr/local/bin:/usr/bin:/bin

You can display your search path with echo $PATH and find the full location of find with which find .

No idea what version of find comes with MacOS ... if you're really interested in source code, you could download the version typically installed on linux systems here: http://ftp.gnu.org/pub/gnu/findutils/
