So I’m trying to update [GitHub - cstook/LTspice.jl: julia interface to LTspice](https://github.com/cstook/LTspice.jl) to work with modern Julia/LTspice and I’ve run into a strange problem.

When I run the following command in cmd

```julia-auto
LTspice.exe -b -Run C:\path\to\test2.asc

```

It generates various log files in the same folder as `test2.asc`

However when I run the same command with Julia `run` no files get generated anywhere I can see.

```julia-auto
julia> run(`LTspice.exe -b -Run C:\Users\torfi\Documents\programmingFun\ltspice\test2.asc`)
Process(`LTspice.exe -b -Run C:UserstorfiDocumentsprogrammingFunltspicetest2.asc`, ProcessExited(0))

```

Does `run` run commands in some kind of special context that the .exe can detect?  
Or can `run` somehow suppress the creation of files?

I think this is your problem:

You either need to quote the backslashes (i.e. double them `C:\\path\\...`) or make them forward slashes (i.e. `C://path/…), both directions are valid in Windows.
