How to add environment or path variables in linux

I am exploring Golang as C and C++ are the main languages being used in the company I work now. Even though I do not see a future where I have to code in Golang, I just wanted to explore the Hello World with it.

Instead of installing it as part of package manager, this time I downloaded the binaries and wanted to set the environment path containing go command file.

Download the binaries.#

Go to golang download page and download the version you want for linux.

Explod the same as following:

$ tar xvzf ./go1.12.6.linux-amd64.tar.gz

Add to path variable#

Add the following entry at the end of the .bashrc file under your home directory (/home/ashokma/.bashrc)

$ export GOPATH=/home/ashokma/projects/go
$ export GOROOT=/home/golang
$ export PATH=${PATH}:${GOROOT}/bin:${GOPATH}/bin

Load the configs:#

Unlike other systems, in linux we can just load the startup configs using source util.

$ source /home/ashokma/.bashrc

Vola \O/ That is it! Now, when we try the go in terminal linux knows where to find it.

$ go
Go is a tool for managing Go source code.

Usage:

go <command> [arguments]
