UsageLine: "go version [-m] [-v] [file ...]",

Short: "print Go version",
|

Long: `Version prints the build information for Go executables.
|
||||
|
||||
Go version reports the Go version used to build each of the named
|
||||
executable files.
|
||||
|
||||
If no files are named on the command line, go version prints its own
|
||||
version information.
|
||||
|
||||
If a directory is named, go version walks that directory, recursively,
|
||||
looking for recognized Go binaries and reporting their versions.
|
||||
By default, go version does not report unrecognized files found
|
||||
during a directory scan. The -v flag causes it to report unrecognized files.
|
||||
|
||||
The -m flag causes go version to print each executable's embedded
|
||||
module version information, when available. In the output, the module
|
||||
information consists of multiple lines following the version line, each
|
||||
indented by a leading tab character.
