[julia-users] readall() from osascript process (MacOS X)?

[cormullion]

I'd like to get some information from running the `osascript` command on 
MacOS X, For example:

    julia> run(`osascript -e "display dialog \"Character\" default answer 
\"#\""`)
    button returned:OK, text returned:#

    julia> typeof(ans)
    Void

I tried to use `readall` to read the result that's printed/returned, but no 
luck.

    julia> readall(run(`osascript -e "display dialog \"Character\" default 
answer \"#\""`))
    button returned:OK, text returned:#
    ERROR: MethodError: `readall` has no method matching readall(::Void)

Anyone know of a trick to get information back from this process?
