We’ve recently upgraded from 0.6 to 1.0 and have found that whos() seems to have gone away. Can someone please verify that this is true? What has replaced it?  
Thanks. -David

When upgrading from 0.6 to 1.0, it’s very useful to try the code in 0.7 first to get deprecation warnings such as this one:

You may try `Base.varinfo()`. There are other useful functions and macros in `InteractiveUtils`…

imho : we can use docker(` julia:0.7` image) to print this information

`docker run -it --rm julia:0.7 julia -e 'whos()'`

```julia
# docker run -it --rm julia:0.7 julia -e 'whos()'
WARNING: Base.whos is deprecated: it has been moved to the standard library package `InteractiveUtils`.

I wish we could have but 0.7 wasn’t approved at work so it never got installed.  
Guess I could have tried it at home, but I try not to bring work home.

Next time we do an upgrade I’ll keep an eye on any versions we skipped over.  
Thanks for the tip!

@zgornel: Thank you, that solves our needs.

You can also check the [history file](https://github.com/JuliaLang/julia/blob/master/HISTORY.md). `whos` is mentioned.
