By entering <code>$PATH</code> on its own at the command prompt, you're trying to run it. This isn't like Windows where you can get your path output by simply typing <code>path</code>.

If you want to see what the path is, simply echo it:

<pre><code>echo $PATH
</code></pre>

You need to use the command <code>echo $PATH</code> to display the PATH variable or you can just execute <code>set</code> or <code>env</code> to display all of your environment variables.

By typing <code>$PATH</code> you tried to run your PATH variable contents as a command name.

Bash displayed the contents of your path any way. Based on your output the following directories will be searched in the following order:

<pre><code>/usr/local/share/npm/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/usr/local/bin
/usr/local/sbin
~/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
/opt/X11/bin
/usr/local/git/bin
</code></pre>

To me this list appears to be complete.

This seems quite ugly and might be <a href="https://stackoverflow.com/questions/14616981/homebrew-install-issues">giving me issues</a> with getting Homebrew up and running as well.

How can I see the current value of my $PATH variable on OS X?

Windows

Python

MacOS
