This is possible now that we no longer support go1.12 and brings rclone into line with standard practices in the Go world. This also removes errors.New and errors.Errorf from lib/errors and prefers the stdlib errors package over lib/errors.

Short: `Show the version number.`,

Show the rclone version number, the go version, the build target
|
|
OS and architecture, the runtime OS and kernel version and bitness,
|
|
build tags and the type of executable (static or dynamic).
|
|
|
|
For example:
|
|
|
|
$ rclone version
|
|
rclone v1.55.0
|
|
- os/version: ubuntu 18.04 (64 bit)
|
|
- os/kernel: 4.15.0-136-generic (x86_64)
|
|
- os/type: linux
|
|
- os/arch: amd64
|
|
- go/version: go1.16
|
|
- go/linking: static
|
|
- go/tags: none
|
|
|
|
Note: before rclone version 1.55 the os/type and os/arch lines were merged,
|
|
and the "go/version" line was tagged as "go version".
|

|
If you supply the --check flag, then it will do an online check to

compare your version with the latest release and the latest beta.
