Hi All,  
sorry if this dumb and not pure ruby q, but i just hit a bump on  
capistrano.

how does one get a result of a run or sudo?

eg,

task :testing do  
x = run “date”  
p x  
end

it runs without error but i get nothing (nil ie) from x

kind regards -botp

Hello botp,

Use backstiks:

> > x = `date`  
> > =\> “Sun Jan 17 16:18:45 CET 2010\n”
> 
> > p x  
> > “Sun Jan 17 16:18:45 CET 2010\n”  
> > =\> nil

Cheers,

I don’t know why you’d want to run ‘date’ instead of Time.now from  
within  
Ruby, but the one reason I can think of is that Capistrano’s #run isn’t  
the  
equivalent of #system – it runs a command on the remote system. I’m  
guessing  
the point here is to do something with the remote system’s date,  
specifically.  
In that case, `date` is useless, as backticks run commands locally.
