I have attempted to add, export PATH="$PATH:/Users/My_Name/desktop/My_Folder", to .bash_profile, .bashrc, and .profile. I executed the command source ~/.bash_profile, source ~/.bashrc, and source ~/.profile to refresh the $PATH and it does reflect that when I execute echo $PATH.
However, when I open a new terminal and execute echo $PATH it is unchanged.
The issue is my system (macOS Big Sur) will not recognize the updated $PATH when I open a new terminal unless I execute the source command every time to refresh my $PATH.
For context, I edited all three because I have scoured multiple sites for suggestions and have exhausted all my options.
Solution: I realized that I was using zsh. To change I executed chsh -s /bin/bash to change my shell to bash.

You need to open your .profile file in an editor like nano or pico and make sure your command is at the bottom of the file. Also, make sure you close your quotes like this:
export PATH="$PATH:/Users/My_Name/desktop/My_Folder"
You might also consider placing the new path at the front like this:
export PATH="/Users/My_Name/desktop/My_Folder:$PATH"
I have an alias in my profile folder called reBASH looks like this
alias reBASH='source ~/.bash_profile'
So that when I change .bash_profile, I merely type reBASH, hit enter and it gets applied to the current session ... just something you might consider as a convenience when doing things like this.

I am trying to create a permanent alias for my terminal. I put the alias in my ~/.profile, ~/.bashrc, and ~/.bash_profile files, previously empty. When I start a new terminal, bash does not recognize the alias, but if I source any of them, it does. Why are these not getting run when I open a terminal? I am on OSX.
Newer MacOS versions use zsh as the default shell for both Terminal and iTerm2. Run echo $SHELL to confirm if this is the case for you.
Zsh looks for a .zshrc file upon shell startup, so to continue using zsh while sourcing the contents of your bash profile, you can run the following:
echo "source ~/.bash_profile" >> ~/.zshrc
Open a new terminal window for the changes to take effect.
Two things need to happen here when using iTerm to get the loading of dotfiles to work.
First you should add the following to your .bash_profile
[[ -s ~/.bashrc ]] && source ~/.bashrc
Secondly you will need to ensure that in iTerm preferences your terminal is set to launch a login shell.
Hope this helps!
Using the default mac terminal, what worked for me was to add a command to run on start up to source my .bash_profile.
Preferences > Profile > Startup > Add command 'source ~/.bash_profile'
Mac terminal preferences window screenshot
Might be considered to be a bit hacky, but it does the trick.
Adding source ~/.profile to my .bash_profile worked for me.
As of High Sierra, both Terminal and iTerm want to load ~/.profile first. So I suggest you put one line in your .profile to make your Mac work like other Unixes:
source ~/.bash_profile
By editing this one file, you won't have to search through the menus of multiple apps to override Apple's bizarre behavior in each.
As of Catalina the default shell is now zsh. You can change it back to bash with chsh -s /bin/bash and that should load your .profile or .bash_profile
Why are your shell's initialization files not loading?
As with most things, It Depends ™
I recently experienced the same phenomenon and went through the following exercise to resolve it:
I use iTerm. iTerm runs a login shell by default. Verify in iTerm Preferences > General > Command > (*) Login Shell
Therefore, I know that ~/.bash_profile will always be called.
Knowing that, I put the following in my ~/.bash_profile file:
for file in ~/.{bashrc,bash_exports,bash_aliases,bash_functions}; do
[ -r "$file" ] && source "$file"
done
unset file
Notice that I use separate files for .bashrc, .bash_exports, etc. It keeps things separate and simple.
Note also that /etc/profile is loaded first, but since I have never used that system wide init file, I knew that that was not my problem. For details check out $ man bash
So, I started with my ~/.bash_profile file.
I found that when I installed Canopy Express that it's installer replaced the contents of my ~/.bash_profile file with the following content:
# Added by Canopy installer on 2017-04-19
# VIRTUAL_ENV_DISABLE_PROMPT can be set to '' to make the bash prompt show that Canopy is active, otherwise 1
alias activate_canopy="source '/Users/lex/dev/python/User/bin/activate'"
# VIRTUAL_ENV_DISABLE_PROMPT=1 source '/Users/lex/dev/python/User/bin/activate'
p.s. Canopy is an excellent, free python IDE, that I highly recommend.
Fortunately, I backup my ~/.bash* files so restoring that was easy and quickly fixed my issue.
My advice would be to understand the order of calls to your initialization files and start with the first one and work your way through them until you find the problem.
Oh, and you may want to verify which shell you are using (I use bash):
~ $ echo $SHELL
/usr/local/bin/bash
I am guessing you may use another shell, such as bash, tcsh, sh, zsh etc.
Put source .bash_profile into your appropriate 'bashrc' file will make the auto loading recovered, i.e.
.login for tcsh, .bash_profile for bash, .zshrc for zsh
My issue was solved by unchecking Preferences > General > tmux >
Use "tmux" profile rather than profile of the connecting session
Most likely, you need to create the files yourself as they appear not to exist by default. You should give them execute permission to make them run.
~ % sudo chmod 700 ~/.bash_profile
Also, you should check the ownership of the files. They should belong to current user rather than root. Otherwise, you will get permission denied error.
~ % ls -a -l
~ % sudo chown <user_name> ~/.bash_profile
Finally, please note that bash looks in your home directory for .bash_profile, .bash_login, and .profile in order. Bash will stop looking if the first is found.
This means if you have both .bash_profile and .profile files, the .profile will not run.
For more information
Hope this would help you.
Little late to the party but it seems that the file .zprofile is the equivalent to that of .bash_profile when loading zsh. I used this instead to execute a few commands on startup. Of course this only valid for a specific iTerm setup with zsh.
https://zsh.sourceforge.io/Intro/intro_3.html
I've used bash for two years, and just tried to switch to zsh shell on my OS X via homebrew. And I set my default (login) shell to zsh, and I confirmed it's set properly by seeing that when I launch my Terminal, it's zsh shell that is used in default.
However, when I try to enter bash shell from within zsh, it looks like not loading ~/.bash_profile, since I cannot run my command using aliases, which is defined in my ~/.bash_profile like alias julia="~/juila/julia", etc.. Also, the prompt is not what I set in the file and instead return bash-3.2$.
For some reasons, when I set my login shell to bash, and enter zsh from within bash, then ~/.zshrc is loaded properly.
So why is it not loaded whenever I run bash from within zsh? My ~/.bash_profile is symbolic linked to ~/Dropbox/.bash_profile in order to sync it with my other computers. Maybe does it cause the issue?
Open ~/.zshrc, and at the very bottom of the file, add the following:
if [ -f ~/.bash_profile ]; then
. ~/.bash_profile;
fi
Every time you open the terminal, it will load whatever is defined in ~/.bash_profile (if the file exist). With that, you can keep your custom settings for zsh (colors, and etc). And you get to keep your custom shell settings in .bash_profile file.
This is much cleaner than using bash -l IMO.
If you prefer putting your settings in .bashrc, or .bash_login, or .profile , you can do the same for them.
Similarly, you could also move the common profile settings to separate file, i.e. .my_common_profile, and add the following to both .bash_profile and .zshrc:
if [ -f ~/.my_common_profile ]; then
. ~/.my_common_profile;
fi
An interactive bash reads your ~/.bash_profile if it's a login shell, or your ~/.bashrc if it's not a login shell.
A typical .bash_profile will contain something like:
if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
so .bashrc can contain commands to be executed by either login or non-login shells.
If you run bash -l rather than just bash, it should read your .bash_profile.
Reference: https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html
For those who have just installed zsh and want their alias from bash to work on zsh do the following
Open .zshrc file in vim like so
vi ~/.zshrc
Scroll to the bottom
click "i" to enable write mode
Tell zsh to load items from bash_profile when needed like so
source ~/.bash_profile
Write and quit like so
:wq
Refresh your zsh like so
source ~/.zshrc
That's it. Now all your saved alias in .bash_profile will be ready to use in zsh.
To complement #Keith Thompson's excellent answer:
macOS:
As #chepner puts it succinctly (emphasis mine):
In OS X, bash is not used as part of the initial [at boot time] login process, and the Terminal.app (or other terminal emulators) process exists outside any pre-existing bash sessions, so each new window [or tab - read: interactive bash shell] (by default) treats itself as a new login session.
As a result, some OSX users only ever create ~/.bash_profile, and never bother with ~/.bashrc, because ALL interactive bash shells are login shells.
Linux:
On Linux, the situation is typically reversed:
bash shells created interactively are [interactive] NON-login shells, so it is ~/.bashrc that matters.
As a result, many Linux users only ever deal with ~/.bashrc.
To maintain bash profiles that work on BOTH platforms, use the technique #Keith Thompson mentions:
Put your definitions (aliases, functions, ...) in ~/.bashrc
Add the following line to ~/.bash_profile
[[ -f ~/.bashrc ]] && . ~/.bashrc
Copy the contents from ~/.bash_profile and paste them at the bottom of ~/.zshrc file.
For ZSH users on MacOs, I ended up with a one liner.
At the very bottom of the ~/.zshrc I added the following line :
bash -l
What it does is simply load the .bash_profile settings(aliases, function, export $PATH, ...)
If you decide to get rid of ZSH and go back to plain BASH, you'll be back to normal with no hassle at all.
If this is something that you do infrequently, or it just isn't appropriate to make changes, you can also 'source' the .bash_profile after launching the child bash shell.
. ~/.bash_profile
This will pull in the settings you make in the .bash_profile script for the life of that shell session. In most cases, you should be able to repeat that command, so it's also an easy way to test any changes that you make without needing to do a full login, as well as bring all of your existing shell sessions up-to-date if you make upgrades to the .bash_profile &/or .bashrc files.
For macOS Big Sur (Version 11.5.2)
Open .zshrc
For example: sudo nano ~/.zshrc
At the end of the file add source ~/.bash_profile
Every time you open the terminal the contents inside the bash profile will be loaded.
Recently I installed oh-my-zsh on OS X and set zsh as default shell and faced the same problem.
I solved this problem by adding source ~/.bash_profile at the end of .zshrc file.
I am using a zsh framework called oh my zsh and I have tried most of the solutions listed here and it broke the format for my custom theme. However, these steps worked for me.
Add new alias(es) at the bottom of my .bash_profile
vi ~/.bash_profile
Make zsh to load items from .bash_profile
source ~/.bash_profile
Refresh zsh
source ~/.zshrc
Restart OSX Terminal app
Try your new alias!
If you'd like to be "profile-centric", you can create .profile as a single source of truth, then load it from both .bash_profile and .zprofile.
.profile
export PATH="/usr/local/opt/python/libexec/bin:$PATH"
# etc., etc.
.bash_profile and .zprofile
if [ -f ~/.profile ]; then
. ~/.profile;
fi
I found this helped bash scripts find the right PATH, etc., and helped me keep configuration in one place.
I have installed Hadoop and every time I want to run it, first I have to do this:
source ~/.bash_profile
or it won't recognize the command hadoop
Why is that?
I am on OSX 10.8
Now that we've narrowed down the problem:
Run ps -p $$ at the command line to check if you are, in fact, using a bash shell.
Realize that you are in zsh, which means you should be editing your profile in .zshrc.
Copy the offending lines from .bash_profile to .zshrc, OR
Modify your .zshrc to directly source your .bash_profile.
UPDATE: Do what #TC1 mentions in the comments and keep the shell-specific code in each shell's own profile, and from those profiles, only source shell-agnostic code.
On Mac Catalina, I just had to open "preferences" on terminal and change the "shells open with" from "default" to "Command(complete path)", which the default path was "/bin/zsh". touch ~/.zshrc, if that file doesn't exist already, and copy/paste your stuff from ".bash_profile" into the ".zshrc" file.
To elaborate, with terminal running, I opened "settings" from the Terminal menu on the Mac navbar. On the "General" tab, look for "Shells open with" select "Command (complete path)", and type in /bin/zsh.
bash_profile.sh is applicable for bash shell.
if your default shell is not bash and if your default shell is someother shell for example zsh then you have to manually load the .bash_profile using source ~/.bash_profile.
You can always change the default shell to bash shell so that the .bash_profile file will be automatically loaded.
Inorder to automatically load .bash_profile, you can update your default shell to bash using the command chsh -s /bin/bash
cat /etc/shells will list the default shells available in the
machine
echo $SHELL will display the currently active shell in your machine
To change active shell to a different shell, use chsh -s /bin/bash.
Then echo $SHELL to verify if the shell has changed.
Terminal -> Preference -> profile -> Shell -> Run command : source ~/.bash_profile
Tick on run inside shell.
After doing all those , just logout and check weather everything works fine or not
I tried the approved answer. Changing the .zshrc file works for one of my machines. But for the other one, when I run ps -p $$, it is -sh under the command. And I changed both bash and zsh files, neither of them works for me this time.
So I found this
https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html
it mentioned
"When Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. "
so I went to that file /etc/profile and add "source ~/.bashrc" in that file. Then it works since every time a terminal is opened, it runs the command in that /etc/profile file.
Not sure if this is the best solution but it works.
sudo nano /etc/bashrc and change that, restarted the terminal and it finally remembered with command. Tried ~/.bash_profile and ~/.bashrc without success, just wasn't sourcing it.
Go to “Preferences/Profiles then look in the right window and find “shell”.
Once in that if your “Startup Run Command” hasn’t been turned on. Click the box to turn it on and in the command section type:
(If you made a .zsh file)
source .zsh ; clear
(If you made a .bash_profile)
source .bash_profile ; clear
Doing this ; clear
Will clear your terminal to a new page so that you don’t see your terminal display:
“Last login: etc
User#user-Mac ~ % source .zsh
If you typed the commands as I said you should just get this:
User#user-Mac ~ %
That way you will be greeted with a clear page with no extra jumbo. Also to make sure that your .zsh or .bash_profile aliases work type the following command to see a list of your custom aliases:
Alias
One alias I like to do is
alias LL=“ls -la”
This will display a tree or the directory you are in as well as hidden files.
I'm following a tutorial called Starting a Django 1.4 Project the Right Way, which gives directions on how to use virtualenv and virtualenvwrapper, among other things.
There's a section that reads:
If you're using pip to install packages (and I can't see why you wouldn't), you can get both virtualenv and virtualenvwrapper by simply installing the latter.
$ pip install virtualenvwrapper
After it's installed, add the following lines to your shell's start-up file (.zshrc, .bashrc, .profile, etc).
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
Reload your start up file (e.g. source .zshrc) and you're ready to go.
I am running Mac OSX, and don't know my way around the Terminal too well. What exactly does the author mean by shell's start-up file (.zshrc, .bashrc, .profile, etc)? Where do I find this file, so that I can add those three lines?
Also, what does he mean by reload your start up file (e.g. source .zshrc)?
I would appreciate a detailed response, specific to OSX.
You're probably using bash so just add these 3 lines to ~/.bash_profile:
$ cat >> ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
^D
where ^D means you type Control+D (EOF).
Then either close your terminal window and open a new one, or you can "reload" your .bash_profile like this:
$ source ~/.bash_profile
If you use bash, it usually means ~/.bash_profile.
In Terminal and iTerm new shells are login shells by default, so ~/.bashrc is not read at all. If instructions written for some other platform tell you to add something to .bashrc, you often have to add it to .bash_profile instead.
If both ~/.profile and ~/.bash_profile exist, only .bash_profile is read. .profile is also read by other shells, but many of the things you'd add to .bash_profile wouldn't work with them.
From /usr/share/doc/bash/bash.html:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.
[...]
When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists.
I have Anaconda install, so I add these 3 lines to ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Documents/Python
source /Users/Username/anaconda3/bin/virtualenvwrapper.sh
and then reload profile by:
$ source ~/.bash_profile
I use an approach that I think is easy to maintain.
It also works well if you sometimes use Ubuntu systems, however I will be sure to address the OP's OSX requirement in my answer.
Create a .aliases file with your alias(es) in your home directory, e.g. ~/.aliases
Execute this file from your .bashrc file (this is executed each time for a new shell process) with source ~/.aliases. This is all you would actually need to do for Ubuntu btw.
On OSX call .bashrc from your ~/.profile file, i.e. have ~/.bash_profile contain: source ~/.bashrc
I would like to create an alias that does the following:
Opens TextMate with ~/.bashrc and allows me to edit it
Once I close TextMate, "sources" ~/.bashrc (so if I add a new alias, for example, it will be available immediately)
I tried the following:
alias b="/usr/bin/mate -w ~/.bashrc; source ~/.bashrc"
but it doesn't work: when I close TextMate, the shell doesn't return.
Any ideas?
I hesitate to suggest it, but if this is a feature you really want, you can make something similar happen by setting the PROMPT_COMMAND variable to something clever.
PROMPT_COMMAND is run every time the shell shows the shell prompt So, if you're okay with the shells updating only after you hit Enter or execute a command, this should nearly do it.
Put export PROMPT_COMMAND="source ~/.bashrc" into your ~/.bashrc file. Re-source it into whichever shell sessions you want the automatically updating behavior to work in.
This is wasteful -- it re-sources the file with every prompt. If you can get your editor to leave the old version in a specific file, say ~/.bashrc~ (where the first ~ means your home directory and the last ~ is just a ~, a common choice for backup filenames) then you could do something more like (untested):
export PROMPT_COMMAND="[ ~/.bashrc -nt ~/.bashrc~ ] && touch ~/.bashrc~ && source ~/.bashrc "
then it would stat(2) the two files on every run, check which one is newer, and re-source only if the ~/.bashrc is newer than its backup. The touch command is in there to make the backup look newer and fail the test again.
