I set up some aliases in my .bash_profile on my Max OS X.
It works but when I'm opening a new tab I always have to load my .bash_profile file with this command:
source ~/.bash_profile
How can I make it work for every terminal I'm opening, even if I'm restarting my Mac or Linux computer?
If you use zsh , you can add source ~/.bash_profile
at the end of .zshrc file at the following path: /Users/YOUR USER NAME/.zshrc , then restart your Terminal/iTerm2 app.
Note that this file is hidden. You can press CMD + SHIFT + . in Finder to
see it, Or just open it in default text editor with the following command from terminal:
open ~/.zshrc
Update
You don't need to do this by hand, run the following command:
echo "source ~/.bash_profile" >> ~/.zshrc
* Dont forget to restart your terminal.
The files executed at the start may be several, usually ~/.bashrc for interactive, non-login shells. The kind I assume you are using.
If so, create an ~/.bashrc file and source ~/.bash_profile in it:
if [ -f ~/.bash_profile ]; then
. ~/.bash_profile
fi
This web site has a lot of information about this.
Study this image, as it is a condensed guide
If you do need to find out exactly which file is being executed, take a look at this web page. It has a lot of specific tests to find out what file is setting what.
Specific for Mac-OS (which is an exception and loads ~/.bash_profile) do as is recomended in the site linked in this answer AFTER you confirm that your bash is doing as explained there.
I know this is a pretty old post, but this problem comes and goes quite oftenly and a lot of laborous solutions are offered. The fact is: being aware of a simple info would solve this pretty fast and easy:
LINUX/Unix OS will load the profile files on startup following the rules below (some distros may have other files names, mainly for user local profiles, but the main rule follows this):
Login Shell
First and foremost: /etc/profile is loaded (global settings);
Next: ˜/.bash_profile (local user settings- other files may be found, like ˜/.profile, depending on the distro. Check documentation).
So, if you are in a Login Shell environment, put all your crazy stuff inside ˜/.bash_profile (or the file provided by your distro) and everything will be fine.
Non-login Shell
First and foremost: /etc/bashrc (some distros will load bash.bashrc);
The next file to be seeked and loaded is ˜/.bashrc
And that's why so many people (just like me) got frustrated having to source their ˜/.bash_profile every single time a Terminal was loaded. We were simply inserting info in the "wrong" file- regarding the kind of shell loaded (see above: login, non-login).
More details on variants of the files mentioned above and some info on login vs non-login shell can be found here.
Hope it helps \o/

I am loosing a lot of time searching in internet for the following simple setting.
I installed git (and git bash) in Windows. What I want is just to open Git Bash and be in the directory I want. I don't want to change my home directory, just be in a given directory when I open the program.
More detailed, when I open Mingw / Git bash in Windows, I would like to be in the following folder:
/c/blabla/my_git_repositories
(this corresponds to the windows-style path: C:\blabla\my_git_repositories).
At the moment, I must write the following command every time I open GitBash:
cd /c/blabla/my_git_repositories
is this possible? Which file should i modify?
Actually the program is installed here:
C:\Program Files\Git\mingw64
Thanks
If you want it happening every time you start an interactive shell, add
cd /c/blabla/my_git_repositories
to your shell startup. If your install includes the manpages say man bash and find the INVOCATION section, in a decent pager just /^INV will do it. Or Google knows to interpret a search for man bash as a search for the bash manpage.
Windows doesn't ordinarily support shell logins at all so a lot of the shell's startup-circumstance detection is overkill on Windows. Executing it is extremely fast, but describing exactly how it decides takes a page or two.
The short form is, if the startup was told it's a login shell it reads the login startup files, including (your) ~/.bash_profile, which generally should check for an interactive login and if so source the normal interactive shell startup ~/.bashrc, so ~/.bash_profile should end with something like
[[ $- = *i* && -f ~/.bashrc ]] && . ~/.bashrc
and put whatever you want in ~/.bashrc. That cd, set up your prompt colors, define your favorite shell aliases, add your personal scripts directory to PATH, whatever.
Partial solution when opening the program by clicking on a link.
Right click on the link → properties → Start in: set the value to "C:\blabla\my_git_repositories".
This will work only when you open the application from that link, but could be fine (depending by your needs).
I am trying to refresh my aliases on my Mac (OS Catalina 10.15.6) after defining new aliases in my .bash_profile file with the command:
source ~/.bash_profile
But terminal keeps giving this error message:-bash: s: command not found
This is confusing because for the longest time this command worked. I even had it included in my .bash_profile file as an alias, where it worked fine.
I'm aware the problem could have to do it with an error in my PATH but I've never made any edits to my PATH so have no idea what the issue could be?
Thanks in advance.
My first instinct would be to check both ~/.bashrc, and /etc/bashrc if it exists. That is where I customarily define aliases, and it looks to me as though a bad alias may be your problem.
I'm not saying it was the one you made, although it might be. Just go through your rc and profile files and look for any aliases which might in any way clash with source.
I suspect the source command is working just fine and the problem is a bad line in the ~/.bash_profile itself that looks like it's trying to run a command named s. I would look in there for the problem.
It might help to run it with xtrace on via bash -x ~/.bash_profile – running it in a separate process like that won't have any of the presumably-desired side effects of sourceing it in your current shell, but you can see what it's trying to do so that you can fix it.
(You can also just set -x before the source and get both xtrace and running in the current shell; just be sure to set +x afterwards or your shell session will be full of debug output.)
I've followed these instructions to the letter to move my global npm directory elsewhere, as I was getting permissions issues.
That kinda-worked, but now I can't use npm anywhere unless I input source ~/.profile every time I restart, which is a huge pain.
Is that deliberate? Is there any way around it?
Everything in .bash_profile will be sourced on login.
echo . ~/.profile >> ~/.bash_profile
The way around it is to read and understand the section of the Bash manual that deals with start-up files, and then take appropriate action.
In the latest edition of the Bash manual, this seems to be in section 6.2. The version that ships with macOS is probably older, but there has not been much change in this area lately.
My guess would be that you have a ~/.bash_profile file which takes precedence over ~/.profile, but that is just a guess.
Edit: This post has an answer with a nice graphical flow. It might make sense to source in /etc/profile
This link talks about the different startup files of bash. You can source ~/.profile in one of the start up files automatically rather than type it manually as you are now.
Depending on if you want it to source at login or new terminal window put it in ~/.bash_profile or ~/.bashrc
This link has a good breakdown of the different files as well.
So I'm installing some things for coding and personal usage, and I need to run this in the terminal (I'm on Mac if you didn't read the title).
~/.bash_profile
It just says permission denied, Im running OSX 10.8.4 Mountain Lion. How do I bypass this?
On MacOS: add source ~/.bash_profile to the end of ~/.zshrc.
Then this profile will be in effect when you open zsh.
You would never want to run that, but you may want to source it.
. ~/.bash_profile
source ~/.bash_profile
both should work. But this is an odd request, because that file should be sourced automatically when you start bash, unless you're explicitly starting it non-interactively. From the man page:
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. The --noprofile option may be used when the shell is started to inhibit this behavior.
If you change .bash_profile, it only applies to new Terminal sessions.
To apply it to an existing session, run source ~/.bash_profile. You can run any Bash script this way - think of executing source as the same as typing commands in the Terminal window (from the specified script).
More info: How to reload .bash_profile from the command line?
Bonus: You can make environment variables available to OSX applications - not just the current Bash session but apps like Visual Studio Code or IntelliJ - using launchctl setenv GOPATH "${GOPATH:-}"
As #kojiro said, you don't want to "run" this file. Source it as he says. It should get "sourced" at startup. Sourcing just means running every line in the file, including the one you want to get run. If you want to make sure a folder is in a certain path environment variable (as it seems you want from one of your comments on another solution), execute
$ echo $PATH
At the command line. If you want to check that your ~/.bash_profile is being sourced, either at startup as it should be, or when you source it manually, enter the following line into your ~/.bash_profile file:
$ echo "Hello I'm running stuff in the ~/.bash_profile!"
No need to start, it would automatically executed while you startup your mac terminal / bash. Whenever you do a change, you may need to restart the terminal.
~ is the default path for .bash_profile
I was getting this error on zsh(mac os Big Sur 11.3), This is how i solved this :-
Go to Terminal.
cd /users/<yourusername>
Once you reach here issue a command :
ls -al
You will see a lot of files and one specific file .zprofile. This is your user profile. We need to edit this.
After this we need to edit the file. Issue the below command :
nano .zprofile
Once you issue this command file will be opened for edit. Add the path details for maven.
M2_PATH="/Users//code/apache-maven-3.8.1/bin" //add your path of maven diretory
PATH="${PATH}:${M2_PATH}"
export PATH
press ctrl + X and save the file.
Issue command after saving the file :
source .zprofile
Once done, you will be able to run the mvn command.
If the problem is that you are not seeing your changes to the file take effect, just open a new terminal window, and it will be "sourced". You will be able to use the proper PATH etc with each subsequent terminal window.
I just installed GMT4 (Generic Mapping Tools) from MacPorts and have run into some serious issues with terminal...
When using the ls command in terminal I get the following:
-bash: ls: command not found
To fix this I've tried many things that I read many different places online. I've changed the following files to include /usr and /bin:
~/.bashrc
~/.bash_profile
~/.profile
Doing so gave me back the sudo command which I had previously lost.
However, I still am not able to use ls in a new terminal window without manually exporting the path("new session"). This has been causing problems when I'm running shell scripts that use system functions. So I'm starting to wonder what exactly those three files do and if maybe having three files doing the same thing is causing them to interfere with one another. If anyone can tell me where I need to add these PATHS that would be great; I dunno, maybe I can delete one of these files or something ELSE is conflicting. Right now I just run " export PATH=$PATH:/usr" in each new terminal window and it works for that session.
I'm running Mac OS X 10.6 on a early 2011 MacBook Pro with 4GB of RAM.

The Bash manual actually explains these files fairly thoroughly. However, the manual does not describe how these mechanisms are usually used in practice. What follows is a brief, abridged version of what is common best practice.
.profile is read at login by both sh and bash.
.bashrc is read by non-login Bash shells. By convention, .bash_profile sources .bashrc in turn.
.bash_profile is read at login by Bash. If this file exists, .profile is not read. By convention, .bash_profile should source .profile if it exists.
