How to Check Version and System Information in Julia REPL

Code

In Command Prompt (cmd)

You can verify this with the following code.

C:\Users\JGH>julia -v
julia version 1.11.3

C:\Users\JGH>julia -version
julia version 1.11.3

C:\Users\JGH>julia -e "println(VERSION)"
1.11.3

In REPL

By typing VERSION in uppercase, you can check the version. By entering the function versioninfo(), you can get more detailed information, including the Julia version, OS, hardware, the number of threads, and more.

julia> VERSION
v"1.11.3"

julia> versioninfo()
Julia Version 1.11.3
