macOS 11.2.3 bashrc not reconizing common flags - bash

I am trying to configure my terminal, but my .bashrc file is not recognizing the common flags.
Here is what my .bash_profile looks like:
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
This is what my .bashrc file looks like:
export PS1="\u#\h\w $ "
And this is what my command prompt looks at the end:
$ source .bashrc
\u#\h\w $
Please advise.
Thanks.

MacOS 11.2.3 defaults to the zsh shell so bash dotfiles and prompt formatting will not apply. Type ‘ps’ to verify which shell you are running.

$ mvn -v – command not found

I installed Maven on macOS 10.12.6.
Added environment to .bash_profile file:
export PS1="\h --- \t *************************** \w $ "
export JAVA_HOME=$(/usr/libexec/java_home)
export MAVEN_HOME=/Users/{user}/Documents/Path/Maven/maven_3.3.9
export GRADLE_HOME=/Users/{user}/Documents/Path/Gradle/gradle_6.1.1
export PATH=$PATH:$MAVEN_HOME/bin
export PATH=$GRADLE_HOME/bin:$PATH
After that I save it and set source .bash_profile command in Terminal.
When I try in Terminal input mvn -v command I see:
-bash: mvn: command not found
When I input $MAVEN_HOME I see:
: No such file or directory/Path/Maven/maven_3.3.9
If I use echo $MAVEN_HOME command I see:
/Users/{user}/Documents/Path/Maven/maven_3.3.9
If I input this mvn I see:
-bash: mvn: command not found
JDK on Mac - $JAVA_HOME command in Terminal:
-bash: /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home: is a directory
Can you help me please to understand where I missed.
Thank you very much for your answers, I fixed my problem just like that:
export PATH=/Users/{user}/Documents/Path/Maven/maven_3.3.9/bin:$PATH
After that everything worked as expected.
If you think my method is not good, please tell me why?
Since it is a maven 2+, export M2_HOME (see "What is the difference between M2_HOME and MAVEN_HOME")
And double check what echo $PATH returns after sourcing the .bashrc.
Make sure it:
includes $M2_HOME/bin
ls $M2_HOME/bin does exists.
Check this
1) Review your path, I think you are missing '$' character right before {user}
2) Review execution permission for 'maven_3.3.9/bin/mvn'
3) Make sure you are using Bash as Unix shell (and not zsh or another)
echo $SHELL
# output should look like: '/bin/bash'
4) If you are using bash then add maven's ENV variables to the file ~/.bashrc (or ~/.zshrc if you are using zsh)
5) 'source' your configuration
source ~/.bashrc
Notes
I recommend understand differences between .bashrc and .bash_profile: http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html
If you want to keep your configuration on .bash_profile then just rebooting your system should be enough (to start a login shell which load .bash_profile)

added wrong path to .bash_profile now I can not found any command

I was trying to add conda into my path. But after I added
export PATH="/data1/neyozhyang/anaconda3/bin/conda"
to my .bash_profile I can not use most of the commands like ls anymore.
It is a linux server.
echo $PATH gives me /data1/neyozhyang/anaconda3/bin/conda
while echo $HOME gives me /data1/neyozhyang
You can choose an editor by it's full path and open ~/.bash_profile.
$ /usr/bin/vim ~/.bash_profile
$ /usr/bin/nano ~/.bash_profile
$ /usr/bin/emacs ~/.bash_profile
And modify the PATH line:
export PATH="/data1/neyozhyang/anaconda3/bin/conda:$PATH"
This might help you get back on your feet (although you don't specify your OS)
PATH=$(/usr/bin/getconf PATH)
That gives you something like /usr/bin:/bin:/usr/sbin:/sbin so you should be able to access the base utilities.

Why must I source .bashrc every time I open terminal for aliases to work?

Git was working fine. I have created an alias in Git but the issue is when I tried to reopen the terminal, then I need to run . ~/.bashrc every time in the terminal.
What is the best way I don't need to provide source every time when I reopen the terminal?
What I did?
I am trying to add source of the .bashrc file in this file but it is a read-only file. I am not able to add the source of the .bashrc file in this profile.
open /etc/profile
Added the permission to write in the profile as well, still not able to link the source file.
sudo chmod u+w /etc/profile
Profile:
# System-wide .profile for sh(1)
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
fi
if [ "${BASH-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc
fi
It looks like your terminal emulator is launching bash as a login shell.
If that's the case, it will read /etc/profile for configuration as well as 1 of the following files, if they exist (listed in order of importance) :
~/.bash_profile
~/.bash_login
~/.profile
It will thus ignore your .bashrc file. A correct fix for your situation would be to either configure your terminal emulator to run bash interactively and non-login, or add the following line to your ~/.bash_profile :
[ -f "$HOME/.bashrc" ] && . "$HOME/.bashrc"
Here is a link to the documentation about which files are loaded depending of the type of shell you are running
As per #Aserre's answer i have followed this step to solve this issue
A typical install of OS won't create a .bash_profile for you. When you want to run functions from your command line, this is a must-have.
Start up Terminal
Type cd ~/ to go to your home folder
Type touch .bash_profile to create your new file.
Edit .bash_profile with your favorite editor (or you can just type open -e .bash_profile to open it in TextEdit.
[ -f "$HOME/.bashrc" ] && source "$HOME/.bashrc" Save it and close it
Restart the terminal, It should work
You should write this line source .profile inside your .zshrc file. This is because default shell is zsh. If u don't want to do this solution than u can go for changing the default shell by typing the following command chsh -s /bin/bash then restart your machine or virtual machine. Then no need for source. I hope this will help :) TAKE CARE
If you are using Linux and you want variables set, to persist.
Follow the below steps.
Be the root user -> sudo su
go to etc folder -> cd /etc
open the file bashrc with the editor of your choice -> vi bashrc
set the variable with export command like here I am setting JAVA_HOME ->
export JAVA_HOME=pathHere
Load the bashrc file with command ->
. bashrc
remember to put the dot/period before bashrc.
now JAVA_HOME should be set permanently.
Thanks...

.bashrc not sourced on Intellij IDEA's terminal

I have some aliased defined on my .bashrc that I'd like to use on my Intellij IDEA's terminal. Why is .bashrc not sourced?
.bashrc is only loaded when Bash is running in "interactive" mode. For some reason, IntelliJ defaults to running Bash in non-interactive mode, but this is easy to change. Open the IntelliJ Settings window, then open "Tools -> Terminal", and add -i to the Shell path.
(Note that in this screenshot, I have also changed the default shell, because I'm on a Mac, which makes it difficult to update /bin/bash. Unless you have installed a different version of Bash, do not blindly copy this change!)
Had the same issue with IntelliJ.
Solved this by setting the value /bin/bash --login in setting->Tools->Terminal->Shell path.
/bin/bash --login forces the bash to read the ~/.bash_profile.
https://intellij-support.jetbrains.com/hc/en-us/community/posts/205437150-Terminal-not-sourcing-bash-profile?page=1#community_comment_360000167679
In your home directory, add theses lines to .profile (create the file if it does not exist), in order to source .bashrc:
if [ "$SHELL" = "/bin/bash" ]; then
. ~/.bashrc
fi
For me, changing the line
Exec="/opt/idea-IU-183.4284.148/bin/idea.sh" %f
to
Exec=bash -ic "/opt/idea-IU-183.4284.148/bin/idea.sh" %f
worked. We exploit the hack that the interactive shell loads .bashrc :)
On Mac OSX Catalina, "/bin/bash" and ~/.zprofile worked for me:
Update:
Apple has changed the default shell to zsh. Therefore you have to rename your configuration files. .bashrc is now .zshrc and .bash_profile is now .zprofile.
My settings are in ~/.bash_profile . I solved it using:
echo "source ~/.bash_profile" >> .profile
sudo echo ". ~/.bashrc" >> /etc/bash.bashrc
Because > operator doesn't pass the sudo permissions to the write process.
I did this :
echo ". ~/.bashrc" | sudo tee /etc/bash.bashrc
I noticed that .bashrc isn't sourced only when I first install IntelliJ and run it directly via the idea.sh script in bin/.
Once I create the desktop entry via Tools -> Create Desktop Entry... and start it from the Ubuntu dash, .bashrc is sourced properly.
If you have recently moved to zsh from bash then go to ~/.zshrc file and update $PATH variable there:
Default value in .zshrc:
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
Change to same PATH variable set in .bashrc and uncomment it
# If you come from bash you might have to change your $PATH.
export PATH=$HOME/bin:/usr/local/bin:<my-bash-paths>:$PATH
None of these answers worked for me. What did work is
sudo nano /etc/environment
...then manually adding my export and alias commands here to make them system wide.
But be careful, do NOT mess up the PATH or you'll have trouble logging back in to your desktop environment, or many other issues.
I had this problem because the default shell had been changed to zsh.
I echoed the shell name with echo $SHELL to see this (thanks How to get default shell).
Then I changed it back to /bin/bash with this command: chsh -s /bin/bash (thanks https://apple.stackexchange.com/a/100476/176809).
Create a bash script with the content;
echo "source ~/.bash_profile" >> .profile
Then in Intellij go to preferences/tools/Startup Tasks;
create a run configuration that runs your bash script and you're good to go.
I just restarted my MAC and it picked up the new stuff.
For me at least, the only thing that works was to put this in the Shell path variable inside of Tools > Terminal :
/bin/bash --rcfile ~/.bashrc

How to make OS X to read .bash_profile not .profile file

I have read so many suggestions about, not putting your customization aka commands in ".profile" file. Rather, create a .bash_profile for yourself and add your alias and etc.
But,when I open the new terminal, if there is only .bash_profile, OS X is not exporting/sourcing the commands mentioned in it. I have to manually source the .bash_profile.
If I create .profile file, on opening a new terminal, all my commands in .profile are executed and will be available readily.
Could you please help me in understanding, how does it works? Also, when to use .bashrc/.profile/.bash_profile files.
Thanks!
According to Apple,
zsh (Z shell) is the default shell for all newly created user accounts, starting with macOS Catalina.
So you should verify your default shell with the command:
$ echo $SHELL
If the result is /bin/bash your default shell is BASH, and if the result is /bin/zsh the default is ZSH.
Go to home with $ cd ~/ and create the profile (if it does not exist) and edit it with the commands:
For bash:
$ touch .bash_profile
$ open .bash_profile
For ZSH:
$ touch .zprofile
$ open .zprofile
According to the manual page that ships with OS X:
... 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.
It should only read ~/.profile as a last resort if neither ~/.bash_profile nor ~/.bash_login are readable.
On all of my OS X systems, I have my ~/.bash_profile set to:
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
It is highly recommended that you do this on OS X in order to get bash to read your ~/.bashrc file like you would expect.
It's also possible that your terminal shell is defaulting to sh instead of bash. You can verify this first:
$ echo $SHELL
/bin/tcsh
To change this to bash, you can go into your Terminal -> Preferences -> Startup tab, and change "Shell Opens With:" from "Default login shell" to Command and value "/bin/bash".
Alternately, you can change your default shell by executing the following command at the command prompt:
chsh -s bin/bash
After you do one of these, open a new shell window, and your .bash_profile should be sourced.
For anyone else who finds this, instead of bash_profile, for new versions of mac you can use .zshrc. I.E., do
open .zshrc
and add what you need there.
You can use zsh to fix the problem.
The Z shell (also known as zsh) is a Unix shell that is built on top
of bash (the default shell for macOS) with additional features. It's
recommended to use zsh over bash.
Installation
Install zsh using Homebrew: $ brew install zsh
Install Oh My Zsh: $ sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
Move to .bash_profile setting .zshrc file
To apply the changes you make you need to either start new shell
instance or run: source ~/.zshrc
If you are using zsh, you can source to .bash_profile by adding the following line to .zprofile
if [ -f ~/.bash_profile ]; then
source ~/.bash_profile
fi
It should be mentioned that bash will first look for a /etc/profile file, as stated in the Bash man pages.
When bash is invoked as an interactive login shell, or as a non-inter-
active shell with the --login option, it first reads and executes com-
mands 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.
I solved by simply adding bash (in a newline) into ~/.bash_profile file.
