$ sudo wget https://golang.org/dl/go1.15.5.linux-amd64.tar.gz

Next, extract the tarball to /usr/local directory.

Add the go binary path to .bashrc file /etc/profile (for a system-wide installation).

export PATH=$PATH:/usr/local/go/bin

After adding the PATH environment variable, you need to apply changes immediately by running the following command.

$ source ~/.bashrc

$ cat > hello-world.go

package main

import "fmt"

}
