macOS (OS X): Change your PATH environment variable

You can add path to any one of the following method:

$HOME/.bash_profile file using export syntax.
/etc/paths.d directory.

Method #1: $HOME/.bash_profile file

The syntax is as follows:

In this example, add /usr/local/sbin/modemZapp/ directory to $PATH variable. Edit the file $HOME/.bash_profile , enter:
vi $HOME/.bash_profile
OR
vi

/.bash_profile
Append the following export command:

Save and close the file. To apply changes immedialty enter:
source $HOME/.bash_profile
OR
. $HOME/.bash_profile
Finally, verify your new path settings, enter:
echo $PATH
Sample outputs:

Method #2: /etc/paths.d directory

Apple recommends the path_helper tool to generate the PATH variable i.e. helper for constructing PATH environment variable. From the man page:

The path_helper utility reads the contents of the files in the directories /etc/paths.d and /etc/manpaths.d and appends their contents to the PATH and MANPATH environment variables respectively.

(The MANPATH environment variable will not be modified unless it is already set in the environment.)

Files in these directories should contain one path element per line.

Prior to reading these directories, default PATH and MANPATH values are obtained from the files /etc/paths and /etc/manpaths respectively.

To list existing path, enter:
ls -l /etc/paths.d/
Sample outputs:

You can use the cat command to see path settings in 40-XQuartz:
cat /etc/paths.d/40-XQuartz
Sample outputs:

To set /usr/local/sbin/modemZapp to $PATH, enter:

OR use vi text editor as follows to create /etc/paths.d/zmodemapp file:
sudo vi /etc/paths.d/zmodemapp
and append the following text:

Save and close the file. You need to reboot the system. Alternatively, you can close and reopen the Terminal app to see new $PATH changes.

Conclusion

Use $HOME/.bash_profile file when you need to generate the PATH variable for a single user account.
Use /etc/paths.d/ directory via the path_helper tool to generate the PATH variable for all user accounts on the system. This method only works on OS X Leopard and higher.

thank you for this.

to append multiple executables in one group, e.g ‘modemZapp2’:
sudo -s ‘echo “/usr/local/sbin/modemZapp2” >> /etc/paths.d/zmodemapp’

Thank you for your useful article! It helped me a lot!

I cannot get this to work. You write “Save and close the file”. How do I do this please?

The author does not explain this but the commands ‘vi’ in the terminal starts an editor called vim. According to the link below you can just type ‘:x’ (without the ‘) and then enter to save and close at the same time

I would like to be able to use gcc to compile a file.
I see gcc-4.0 and gcc-4.2 in /Developer/usr/bin/
echo “$PATH” gives me this:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/MacGPG2/bin:/usr/X11/bin
If I need to set the path also to /Developer/usr/bin/ where my gcc is (I mean I guess I have to do that, not even sure) I am kind of lost. I append this:
vi $HOME/.bash_profile
Then I see in he Terminal many line breaks with

in front, the cursor is before all these breaks and at the bottom I read “”

/.bash_profile” [New File]” (in my firs attempts it was written “INSERT”).
If I paste “export PATH=$PATH:/Developer/usr/bin” there, I don’t know how to go further. If I then paste “source $HOME/.bash_profile” after, I get a mess: I had to re-install xcode everytime I messed up with the Terminal which kept on scrolling and scrolling with error messages.

Actually as soon as I paste “export PATH=$PATH:/Developer/usr/bin”, he word “INSERT” comes up at the bottom replacing ”

/.bash_profile” [New File]”
So I guess from now on I should save my new bash_profile, bu I do not know how.

I got it to work. gcc never worked, but g++ did.
Now the ./a.out command form the script I want to create is not working. Nerverending story. FIle not found no matter where my source file is.

When I did echo “$PATH”, I got
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

In my .bash_profile file, I have put
PATH=”/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:$PATH”
export PATH

But, when ever I execute a command, I need to give the full path in the command. For example,
when I take update in SVN. The command should be “svn update” but in my case i need to give “/usr/local/bin/svn update”. It happens for me in every command.
FYI: I am using OS X Yosemite, 10.10.3

Is there anything I need to change in resolving this issue ? Thanks in advance.

The reason why this is happening is because you are not pointing your “$PATH” to a folder with ONLY Mach-O 64-bit executable x86_64. In order to do this, please follow this tutorial: https://www.objc.io/issues/6-build-tools/mach-o-executables/. Long story short, to make for example an executable file from a C file “.c”, use the terminal tool xcrun with clang as an argument followed by the name of your “.c” file…This will look something like xcrun clang helloworld.c. This in turn will generate the desired “Mach-O 64-bit executable x86_64”. The file will look something like: a.out (“The file is called ‘a’ because it is the default name if given no parameters for such”). Now you can take this “a.out” file and rename it to whatever you want your command to be when you are calling it from terminal. Now after renaming your file, put it in a folder where ONLY Mach-O 64-bit executable x86_64 will be located and put this folder in your “$PATH” using any of the options listed in this article and finito!. Now you can call your file with the desired named from the terminal.

Conclusion : If you want additional values to your path for all users, you just have to create a new file in /etc/paths.d and put, on per line, additional paths that are required.

Conclusion : Specific roles taken up from time to time by users could need different environment settings. Ex – Dev role by the administrator could need the XAMP stack, and access to executing Apache, MySQL and PHP. Though Apache and PHP come built-in along with Yosemite, their bin directories are not set in the PATH variable.
Hence, we can have .bash_profile_dev in the HOME of the administrator, with all the PATH settings and command line conveniences for starting / stopping servers, etc as the need arises. This can be executed whenever the user needs to change their role, by running

Question: Q: entering a file path into Finder or elsewhere?

can anyone help me if there are one or more ways to find a path like this in finder or other software? i have recently realized that i don’t know how to take a file path such as this and then get my mac to show me where this is without «manually» finding it myself. also, i would love any other info on this type of topic or closely related topics if there are any that a new user should be aware of.

You can type Command + Shift + g while in any Finder window or select «Go to Folder…» from the «Go» menu & type in or paste in a filepath. Press the «Go» button & you are there.

CMD+Shift+g means to hold down the command & shift keys & then tap the «g» key. This shortcut is built into the Finder; you don’t need to add it.

You can see this indicated in Finder’s «Go» menu: next to «Go to Folder…» you will see «⇧⌘G» to help you remember this keyboard shortcut.

The hollow up arrow is the system wide menu symbol for the shift key. You will also sometimes see the ⌥ symbol (for the option key) & the ^ symbol (for the control key) in menus. They are all modifiers keys that you hold down while typing other keys to modify their behavior.

Can I please ask you where i find this CMD+Shift+g in the MacOS? I mean, presumably I can customize this if I want and I am not finding it in the preferences under Keyboard Shortcuts.

thank you very much.

i am new to the OS and trying to get caught up on a couple of things.

so this is a «hard-coded keyboard shortcut» that is basically embedded into the OS and I cannot change it and the ones that I can change are located in the Preferences Keyboard Command section is that right?

i mean, the ones I can change i can see in the Preferences and the ones that I cannot change and they are listed here is that correct?

That particular keyboard shortcut is coded into the Finder, which is an application even though we don’t usually think of it that way. In other apps, it might do something else, or nothing at all. For instance, in Safari, «⇧⌘G» is the shortcut for finding the previous instance in a search (it’s on the «Find» menu item of the «Edit» menu).

You are right about the Keyboard Shortcuts section of the Keyboard system preference. Note that you can also create shortcuts as well as change ones that appear there, & they can be either «global,» applying to all apps or specific to a selected app. However, the shortcuts you create will not override ones coded into an app.

If you click the purple question mark icon in the preference, the help topic that appears will give you a little more info about this.
