How can I see the current value of my $PATH variable on OS X?
You need to use the command echo $PATH to display the PATH variable or you can just execute set or env to display all of your environment variables.
By typing $PATH 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:
/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/binTo me this list appears to be complete.
By entering $PATH 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 path.
If you want to see what the path is, simply echo it:
echo $PATH
To list out the paths as individual lines, you could use:echo "${PATH//:/\n}"
