Simple command line tool that will download the latest version of Go.
It may seem a little chicken and egg for a tool written in Go to be used to download Go. However due to the statically compiled nature of Go there is no dependency on the Go language package to run this tool.
The idea is for this tool to be used in automated build pipelines to download the latest version of Go. It therefore becomes simpler to automate compiling your Go project with the latest Go version without having static version numbers in your configuration.
The checksum is verified as part of the download process.
On a host that already has Go installed:
go get -u github.com/jcmturner/getgo
To simply download the latest Go version, to the current working directory, corresponding to the OS and architecture getgo is run on:
./getgo
The OS, architecture and path to download to can be specified using arguments:
Usage of getgo:
-arch string
Architecture type of release to download
-info
Show latest Go version only, do not download
-kind string
Kind of release to download (default "archive")
-os string
OS type of release to download
-path string
Path into which to write download (default "./")
If the GOOS and GOARCH environment variables are set these will be used if the -os and -arch are not provided.
To get the latest version information without downloading use the -info switch.
