updatego

updatego

An absolutely unnecessary utility to install/update Go in my machine. It probably won't work for you unless you use a similar setup as mine.

Pre-requisites

For this to work, you need to have Go install to in /usr/local. You also should have the following lines added in your ~/.bashrc:

export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:$(go env GOPATH)/bin

This will let you take advantage of using Go modules to manage packages and your Go projects.

Build

Just clone and run go build.

Install

If you don't want to build and manage your binary yourself, you can just use the below commands to directly setup the tool in your system:

go get -u github.com/rajshrimohanks/updatego
sudo mv $(go env GOPATH)/bin/updatego /usr/local/bin/

Now you can just do sudo updatego to run the utility.

Usage

You need to run the utility with sudo since it is setting up your Go inside /usr/local.

sudo updatego -version 1.15.5

All options:

  -go-dir string
        the directory inside which the go archive should be extracted (default "/usr/local")
  -version string
        the go version to fetch (default "1.15.5")

Perks

Since all we are doing is just deleting the existing go setup and extracting the new one, we can use this to roll back go versions as well (as if this wasn't obvious, duh!)

sudo updatego -version 1.14.0

Why is this needed?

I totally have no idea. You actually need Go to build this in the first place. You could also use go get to pull in a new version of Go. But go get will only bring your new version as a package. It won't replace your primary install. This utility will do that. So I guess, that's a usecase? :P
