Hi! I'm developing an application, that needs to execute some ruby
files, and log the output in a txt file.
The problem that i have is that i can't take this output.
Here is a piece of code:
filesToExec.each { |file|
system("ruby "+scriptFolder+"/"+file) # I need this output
}
Thanks a lot!

You're looking for something like
puts "ruby #{scriptFolder}/#{file}"

If you only need to save a single line, you can do this:
results = `ruby #{scriptFolder}/#{file}`
If you need to be looking at multiple lines, you should check out IO.popen

With this line results = `ruby #{scriptFolder}/#{file}` i'm saving only
the file location string. It's the same as
results = "ruby "+scriptFoler+"/"+file
You only change the concatantio symbol by printing variables into the
string.
I need to save the cmd output, the output of the script.
So
With this
filesToExec.each { |file|
system("ruby "+scriptFolder+"/"+file) # I need this output
}
I'm running the scripts, that's correct? or i have to do it in other
way?

Using ` instead of " executes the command and returns a string of the output.
Try this in irb:
> > r = `echo "hi"`
> > puts r
and r should equal "hi\n"

NO, its a back tick, not a quote. Look carefully.

Or use %x{} to stand out visually:
output = %x{ruby #{scriptFolder}/#{file}}
