So I was trying to setup the Go programming environment on my Mac and add the necessary directory to the path by modifying the .bash_profile accordingly. After saving the .bash_profile, I tried running "go version" for example but it still didn't work.
After a bit of searching I found that if i did the following:
source ~/.bash_profile
The go version would work. Which it does but it seems that my PATH has been changed since commands such as: nano, vi, ls, sudo etc do not work anymore.
Is there a way of recuperating my initial environment PATH?
Thanks in advance!!
:D
PS - let me know if my issue is not clear
Note that your path is likely just "broken" for your current shell session: Mac OS X doesn't strictly use .bash_profile for your PATH.
My guess is that you didn't write out export PATH=$PATH:$GOPATH/bin and export GOPATH=/Users/sSmacKk/go/ (or wherever you wanted to set it) correctly: if you forget to assign the existing path back to your new path, you'll have problems.
Run path_helper from /usr/libexec/path_helper (which would normally be on your path!)
Add the lines: export GOPATH=/wherever/you/want/ and then export PATH=$PATH:$GOPATH/bin to your .bash_profile
Save and exit from your text editor and then source .bash_profile.

Usually I will nano .zsh_profile
Then I will edit the path
#PYTHON
export PATH=/Users/ffff/Library/Python/3.8/bin:$PATH
# JAVA
export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=$JAVA_HOME/bin:$PATH
#ANDROID
export ANDROID_HOME=/Users/ffff/Library/Android/sdk
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/tools/bin:$PATH
then I will save and exit
Then I will
source .zsh_profile
I will test the Java and ADB all is good, but one I open a new Terminal from my mac, it will say ADB and JAVA and Android_HOME not found
Why is it not persist? Did I miss out anything? My mac version is 12.2.1
The .zsh_profile file, has no special meaning. This is probably a confusion form Bash, where the bash_profile is executes for login shells. In Zsh, that equivalent would be ~/.zprofile. You might have some code in your .zshrc file, that overrides the PATH variable with something else. Because, as oppsed to .zprofile, the .zshrc file gets executed for every interactive non-login shells.
So my advice, checkout .zshrc and see if there's something overriding the PATH there, if so, maybe you want to change that, and NOT to execute these commands you want to add for every time a shell is opened, you should put them in .zprofile, so they only get executed once at login.
I have macOS Sierra version 10.12.6
I tried to add a path using the terminal. I entered source ~/.bash_profile and then a text file opened and I entered my path.
But then the terminal stopped responding and bash commands are not recognizable anymore.
If I enter: source ~/.bash_profile nothing happens.
And if I enter any environment related command an error message shows: -bash: printenv: command not found
How can I fix this?
You've probably messed up your path. When you're setting a path it's important to append to it rather than overwrite, or you lose access to all the system paths; /usr/local/sbin, /usr/local/bin, /usr/sbin etc. When setting a new path make sure you use:
$PATH=$PATH:/path/to/add
You can fix this by removing the line from .bash_profile where you overwrote the path. Please paste the contents of .bash_profile if this does not work.
You've replaced $PATH with some of your values and you might not be able to update .bash_profile because of the unavailability of nano. Use the following command to access nano and environment variables.
export PATH="/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"
After using the command you can use nano ~/.bash_profile to fix the problem.
I created a.bash_profile and defined
export PATH=/user/local/bin
rather than
export PATH=/user/local/bin:$PATH
Then, I ran
source ~/.bash_profile
Now none of the command, e.g., ls works. Is there a way to back out this change? Thank you.
If you have fixed your .bash_profile file, you just restart bash to get your $PATH back. If that's not an option, or you can't fix the file externally, you can do export PATH="/bin:/usr/bin:/usr/local/bin", which should give you enough to get to vi or some other text editor so you can fix your .bash_profile, then you can restart bash.
I'm not able to execute any unix commands on my Mac OS Terminal. I was adding a path to my Scala Installation Location.
You've broken your $PATH environment variable, by the looks of it in ~/.bash_profile.
To fix:
Start Terminal.app (with error message as you posted).
Manually set $PATH:
export PATH=/usr/bin:/bin
Edit your ~/.bash_profile:
vi ~/.bash_profile
Remove the ?? characters from the scala path. That looks like it might be an invisible character, so I would recommend deleting the line and retyping it.
Save and test.
It sounds like you've replaced your path, rather than appended the path to Scala. You'll now need to use the full path to commands and then you'll be able to restore the path.
You can call vi from /usr/bin/vim
I don't know what has happened, but in my Terminal on Mac OSX 10.5 it can no longer find my sudo command, or find command, etc. They are there because if I put /usr/bin/sudo or /usr/bin/find it works fine...
My .bash_login file looks like this:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
My .bash_profile file looks like this:
export PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:/Library/Python/2.5/site-packages/django_trunk/django/bin:/usr/local/mysql/bin:/usr/bin/sudo$PATH"
I'll say now, I don't really know what I'm doing with the Terminal. I'm just a beginner to it all, and I must of done something for the environment variables (is that what they're called?) to be lost. I presumed I'd just have to make sure the /usr/bin/ path is in my bash files, but they are, and it doesn't seem to work. Please help!
Also, when I do use the /usr/bin/find command, it says "Permission denied" to me, even though I am logged into Mac OSX as the System Administrator account. I don't understand.
Any help would be grand. Thank you - James
It looks like both of your PATH exports are malformed:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
The end bit there won't work. It should be:
export PATH=/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:$PATH
Notice the colon before '$PATH'? It's important ;)
Also, the double quotes are not necessary.
If this doesn't work, we will need more information. It is possible that something else is modifying your path even after your shell configurations are loaded.
Can you post the results of:
$ echo $PATH
Configuration files are not always a good indication of the current environment variables, since they are modified by many programs and files, all across your system. To see all of your environment variables, you can run:
$ env
This should fix the problem completely and permanently.
first, export environment paths by using below command in the terminal.
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
now you have the commands you want. (eg. try ls. You'll see the command is working). But this is only for the current session. If you close the terminal and open a new one, you will have the previous issue. To make this change permanent, use below command,
go to home directory
cd ~
open .bash_profile file in nano / vim (I'm using nano here)
nano .bash_profile
This will open up nano editor. In a new line, paste the following;
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:$PATH
press 'control'+'o' to save (WriteOut) and 'control'+'x' to exit nano.
All done ! Now try the commands.

I went trough the same issue and here is how I solved it.
First of all I reverted the file to its original doing this way
/usr/bin/nano ~/.bash_profile
In my case I was not able to make work any command alias. Even vi or vim didnt work without specifying the full path of that command.
If nano is not installed just replace nano in the command by the editor installed
After that just restart the computer. In my case as I said bellow I could not use any command. When trying to do /usr/bin/source ~/.bash_profile
that command failed. So I had to restart the OS and it worked
