How can I see the sfdx version Number in the cli?

Question

So I am trying to see the exact version of the sfdx I am using any hints?

Answer 1

Simple type in the command line interface sfdx -v

Answer 2

CLI Version Information under Troubleshoot Salesforce DX covers this

sfdx plugins --core      // Version of the CLI and all installed plug-ins
sfdx --version     // CLI version

The rest of the CLI commands are noted in Salesforce CLI Command Reference as well as easily shown in the CLI with the following

sfdx commands

And it's always possible to add --help within a given command to understand any specific format/info about it. You can even just do:

sfdx --help

which outputs the following (also displays version).
