I am on Windows and vs code.  
The snippet below prints a ton of verbose mixtex code to the console.  
I thought `read` would circumvent this, but that is not the case.

Any ideas how I can disable this?  
I am looking for a Julia solution (and not some flag for the miktex-pdftex call to disable the information)

```julia
try
           a = read(run(`miktex-pdftex.exe -undump=pdflatex $(tmp_tex_fi) --output-directory=$(tmpfld)`));
        catch er 
            @show er 
        end

```

```julia
julia> try
                  a = read(run(`miktex-pdftex.exe -undump=pdflatex $(tmp_tex_fi) --output-directory=$(tmpfld)`));
               catch er
                   @show er
               end
This is pdfTeX, Version 3.141592653-2.6-1.40.23 (MiKTeX 21.8)
