I was trying to add JAVA_HOME in the path variable.
I downloaded Java JDK and done following:

  • nano ~/.bash_profile

  • added following lines and saved the file:

    export JAVA_HOME=$(/usr/libexec/java_home)

export PATH=$JAVA_HOME/bin=$PATH

  • source ~/.bash_profile

After that I tried to open bash file again using:

nano ~/.bash_profile

It shows:

-bash: nano: command not found

I tried other commands too such as brew doctor, curl, vim, java -version etc. All of them shows command not found error.

What is the solution for this? How can I restore my system?

Updated: Solution that I used:

I run the following commands to set the standard default path that Mac OS uses in the command line:

export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

The line

export PATH=$JAVA_HOME/bin=$PATH

should read

export PATH="$JAVA_HOME/bin:$PATH"

(note the = changing to : towards the end, and I also double-quoted the value for safety in case there are any spaces in any of the pathnames)

You will have to change that using the full path to the nano editor (/usr/bin/nano on macOS)

/usr/bin/nano ~/.bash_profile

... and then restart your shell/terminal. Using source on shell startup files is almost never a good idea as that would add to the existing PATH variable (and possibly to others as well) rather than modify a "clean" version of the variable, and it may have other interesting side-effects if things like tmux or screen are automatically started.

You could also temporarily get a sensible value for PATH so that you can repair the file with nano using 

PATH=$(getconf PATH)
nano ~/.bash_profile

The getconf PATH command returns a PATH string that is supposed to cover all standard utilities. On macOS, this includes the nano editor.

Try to run nano with an absolute path like

/usr/bin/nano ~/.bash_profile

or

/bin/nano ~/.bash_profile

(I don't know where nano is located on your system.)

When adding $JAVA_HOME to PATH in your .bash_profile you have to use : instead of =

export PATH="$JAVA_HOME/bin:$PATH"
