How can I see the current value of my $PATH variable on OS X?
$ $PATH
returns:
-bash: /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: No such file or directory
This seems quite ugly and might be giving me issues with getting Homebrew up and running as well.
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/bin
To 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}"
Use the command:
echo $PATH
and you will see all path:
/Users/name/.rvm/gems/ruby-2.5.1@pe/bin:/Users/name/.rvm/gems/ruby-2.5.1@global/bin:/Users/sasha/.rvm/rubies/ruby-2.5.1/bin:/Users/sasha/.rvm/bin:
for MacOS, make sure you know where the GO install
export GOPATH=/usr/local/go
PATH=$PATH:$GOPATH/bin

echo $PATH(or, in this case, just$PATH) acts more like an array, where each colon (":") is a separator between each entry. It's helpful to imagine a space (or, a new line) at each:.
