[julia-users] run(`...`) return code

[Robert J Goedman]

Is there a way to express:

run(`ls`) == Nothing && run(`ls`)

i.e., the first command could be make, the second executing the program if make 
succeeds?

I looked through 
http://blog.leahhanson.us/running-shell-commands-from-julia.html which is 
really nice, but does not address this.

Thanks,
