From Julia, you can use `Sys.free_memory()` which returns an unsigned integer with number of bytes that are free. If you want it in e.g. MiB do `Sys.free_memory()/2^20`. You can also get it by calling `versioninfo(verbose=true)` although that prints a lot of other info as well.

Note: `versioninfo()` is a part of InteractiveUtils in the Standard Library which is loaded automatically in the REPL. If you want to run it from a script you need to include `using InteractiveUtils` before calling it.
