Hi,  
Can you mention what you mean by not worked? What did you type in the command line, and what was the output?

```julia
$ julia --version
julia version 1.9.0-DEV

```

should work (according to --help), and actually --versio etc. down to -v… unlike for --help (unless with one hyphen).

You can do (if ever needed):

```julia
$ julia -e "println(string(VERSION))"
1.9.0-DEV.432

```

for a slightly more specific version. Or:

```julia
julia> versioninfo() # or for even more verbose info: versioninfo(verbose=true)

Julia Version 1.9.0-DEV.432

`--version` while a common option in Unix/Linux (Windows?) is I think not standardized, except by GNU. I started answering this question assuming it missing…
