Mac OS: Adding a directory to PATH

#Mac OS

To see if a directory is in PATH:

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Note that directories are separated by : symbol. To add your directory to the path, edit your bash_profile:

$ vi ~/.bash_profile

Add the following line of code, assuming you want to add /usr/local/mysql/bin to the PATH

export PATH="/usr/local/mysql/bin:$PATH"

Save your changes. Close your terminal. Open a new terminal. Your directory should be in PATH

$ echo $PATH
/usr/local/mysql/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
