Add the code below to the /etc/profile file for a system-wide installation or ＄HOME/.bash_profile file for a current user installation.
export PATH=$PATH:/usr/local/go/bin
Save the file and load the new PATH environment variable into the present shell session. The command below saves the file into a ~/.bash_profile session.
source ~/.bash_profile
Verify the Go installation by checking the version of Go installed. Use the command below to check.
