Hi, guys,
I have installed my latest Julia releases with juliaup. Below is my status.
How go back to the previous release (1.10.4+0.x64.apple.darwin14 ) ?
I suppose just one commend is sufficient … but I was unable
Thanks for help !!

$ juliaup status
 Default  Channel  Version                      Update 
-------------------------------------------------------
       *  release  1.10.5+0.x64.apple.darwin14

You can do juliaup add 1.10.4 I think, and then run it with julia +1.10.4 (or set it as the default).

If you’re asking how to arbitrarily do one release earlier than the current one (analogous to HEAD~1 for git) I don’t think that’s supported.

Worked perfectly !
Ald how to set the default?

Ideally the juliaup help system should be enough to find out.

$ juliaup
The Julia Version Manager

Usage: juliaup <COMMAND>

  add          Add a specific Julia version or channel to your system. Access via `julia +{channel}` e.g. `julia +1.6`

  list         List all available channels

To launch a specific Julia version, use `julia +{channel}` e.g. `julia +1.6`.
Entering just `julia` uses the default channel set via `juliaup default`.


$ juliaup help default
