adding path in mac

The easiest way to add a new path to $PATH (the environment variable) is with the export command. In this example we’ll add “~/opt/bin” to the user PATH with export:

export PATH=$PATH:~/opt/bin

You can run that directly from the command line, then check the $PATH with echo to show that it has been added like so:

echo $PATH

$path mac

sudo nano /etc/paths

which path variable should i use in mac

export PATH=$HOME/bin:./node_modules/.bin:$PATH
