Go Install Script for Linux

Bash script to automate Go language tools single user or system-wide installation (Linux).

Latest available version for download at the time of this writing was for Go version 1.4.1.

Requirements

• Linux

Is it any good?

Yes

Usage

./install_go.sh [-u] [-b] [-s] [-f] [-x] [-a [32|64]] [-w <string>] [-r <string>] [-p <string>]

Flags:

• -u Update to current version (as defined by script). Update will use your current $GOROOT and $GOPATH to install Go and verify your workspace. This option can be combined with -p and -w or -s to specifiy a new install/workspace directory. The old $GOROOT will be removed.
• -b Rebuild system path variables (use the same flags for a normal install but add this)
• -s Single user install (install to $HOME/.go instead of /usr/local). Effectively equal to '-p $HOME/.go'
• -f Force reinstall of Go. Uninstalls any versions and installs from scratch. Use to switch from single-user to system-wide setup, or simply reinstall go. Uses current $GOROOT and $GOPATH to reinstall go and verify workspace.
• -x Uninstall Go (if $GOROOT is defined)
• -a Architecture type. Valid parameters are 32 or 64. Assumed to be 64.
• -r Release version to install. E.g. 1.3.2
• -p Path for Go install directory
• -w Path for Go workspace

-u and -f must be the first flag if used.

Examples

To install 64-bit (system-wide, default install/workspace directories, simpliest)

$ ./install_go.sh

To install 32-bit:

$ ./install_go.sh -a 32

To uninstall Go (created with this tool):

$ ./install_go.sh -x

Install for a single user:

$ ./install_go.sh -s

Update to latest version (as defined by the script):

$ ./install_go.sh -u

Install a specific version:

$ ./install_go.sh -r 1.3.1

Update to a specific version:

$ ./install_go.sh -ur 1.3.3

Define custom Go install directory:

$ ./install_go.sh -p /path/to/go/dir

Define custom Go workspace directory:

$ ./install_go.sh -w /path/to/go/dir

Force system-wide reinstall:

$ ./install_go.sh -f

Rebuild system Go path variables (default installation):

$ ./install_go.sh -b

Defaults

Go install directory: /usr/local/go

Go workspace: $HOME/go

Read more about the workspace at http://golang.org/doc/code.html

Notes

• If $GOROOT is not defined, this script cannot uninstall Go.
• Uninstalling Go with this tool will not remove the workspace.

Versioning

For transparency into the release cycle and in striving to maintain backward compatibility, This application is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we'll adhere to these rules whenever possible.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

• Breaking backward compatibility bumps the major while resetting minor and patch
• New additions without breaking backward compatibility bumps the minor while resetting the patch
• Bug fixes and misc changes bumps only the patch
