The first two characters in $PATH should probably be .:, not .;.

I have installed python3.6 in my desktop which already had python3.5 and python2.7 inside. I change the default path for both python and python3 to python3.6 but it seems like python-config is still on python2.7 and python3-config is still on python3.5. How can I change the default python3-config or python-config to python3.6-config?
Thanks for the help!
so to elaborate on my comment, python comes usually with a version attached like so
ls -lisa /usr/local/bin/ | grep python
34138948 16 -r-xr-xr-x 2 root wheel 5248 15 Apr. 03:12 python3.7
34138954 0 lrwxr-xr-x 1 root wheel 17 15 Apr. 03:12 python3.7-config -> python3.7m-config
34138948 16 -r-xr-xr-x 2 root wheel 5248 15 Apr. 03:12 python3.7m
34138949 8 -r-xr-xr-x 1 root wheel 2936 15 Apr. 03:12 python3.7m-config
34127071 16 -r-xr-xr-x 1 root wheel 5216 15 Apr. 10:59 python3.9
34127072 8 -r-xr-xr-x 1 root wheel 3153 15 Apr. 10:59 python3.9-config
as you can see some names are already symlinks (the once with the -> ) so if you wanna access python3.9-config as python3-config you need to make a symlink with the name python3-config that points to the binary python3.9-config.
% sudo ln -s /usr/local/bin/python3.9-config /usr/local/bin/python3-config
so which should now give you
% which python3-config
/usr/local/bin/python3-config
looking at the directory again shows the symlink now
% ls -lisa /usr/local/bin | grep python3
34127092 0 lrwxr-xr-x 1 root wheel 31 22 Juni 14:09 python3-config -> /usr/local/bin/python3.9-config

Does anyone know what the * following a filename in macOS terminal means?
All the file names in the folder:
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands
have a * trailing them and I'm not sure why.
For example:
jd#Mypc % ls -laF
total 1200

They have the trailing asterisk because (a) they're executable; and (b) you supplied the -F option to ls.
See the documentation for the -F option in the man page for ls:
-F Display a slash (`/') immediately after each pathname that is a
directory, an asterisk (`*') after each that is executable, an at
sign (`#') after each symbolic link, an equals sign (`=') after
each socket, a percent sign (`%') after each whiteout, and a ver-
tical bar (`|') after each that is a FIFO.
Those files have their executable bit set, e.g.
$ touch foo
$ ls -laF foo
-rw-r--r-- 1 user staff 0 Sep 27 18:33 foo
$ chmod a+x foo
$ ls -laF foo
-rwxr-xr-x 1 user staff 0 Sep 27 18:33 foo*
As for the executable-looking emulator that you can't actually execute, this can happen when the dynamic loader requested by emulator doesn't exist. You can check what kind of file emulator is with the command file emulator, and check what dynamic loader and libraries it needs with ldd emulator (any line showing “not found” is something you need to install). Given the name of the directory and the size of the file, emulator is probably a Linux x86 binary. I suspect you have an amd64 system. If so, you need to install a runtime environment for 32-bit applications; on Ubuntu, you need the ia32-libs package (and perhaps also ia32-libs-gtk). You could also get this error message for a script whose interpreter as indicated in the #! line doesn't exist.

I found these libraries: http://www.g95.org/downloads.shtml. I downloaded the x86 OSX binaries, unzipped the file, and did ln -s bin/i686-apple-darwin10.3.0-g95 /usr/local/bin/g95, and added chmod +rx permissions to all these files, but I still can't run the g95 executable.

Why isn't there a brew formula for this?
I have installed the global npm package jslint and it lives here

lrwxr-xr-x 1 lust admin 40 Feb 12 15:31 /usr/local/bin/jslint -> ../lib/node_modules/jslint/bin/jslint.js

$ which jslint
/usr/local/bin/jslint
$ head -3 /usr/local/bin/jslint

var linter = require("../lib/linter");
So it is without any doubt whatsoever at this point that jslint is in fact being run from this dir and not here:

There appear to be two copies of the package, one in /usr/local/ and one in ~/.npm. Why is there one in .npm and is it safe for me to remove it?
~/.npm is a cache that npm uses to avoid re-downloading the same package multiple times. There's no harm in removing it. You can empty it with the command:
npm cache clean
