my goal is to run a command like

```julia
ranger ~/.julia/ --choosefile=$(joinpath(homedir(),".julia"))

```

however, i get this error when I try to use `~` in the path names

```nohighlight
julia> run(`ranger $("~/.julia/")`)
Inaccessible paths: ['~/.julia/']
ERROR: failed process: Process(`ranger '~/.julia/'`, ProcessExited(1)) [1]
Stacktrace:
 [1] run(::Cmd) at ./process.jl:724
 [2] top-level scope at none:0

```

how can I correctly get julia to build this `Cmd` and execute it?

Call `expanduser` on the path first.
