Getting results from ofSystem

beginners
#1

If I run a command with ofSystem, I can’t see how to get the result back into OF.
Bright ideas welcome :slight_smile:

TIA

[Solved] Can I issue command line prompts and read the output with the OF app?
#2

ofSystem returns a string with the output from the called command

#3

Thanks - I know it prints to cout, but I can’t see a method that lets you put it in a string in OF.

#4 
string result = ofSystem("ls");

should work

#5

No - this does nothing. The string always has a length of 1, but should be at least 16.
The console shows the correct listing though.

Of course
string result = (“Test…”);
and print to screen works perfectly.

#6

Suggested
string result = ofSystem("ls");
Works here fine. I’m on OSX

#7

I think it is Xcode being cranky - the result would appear in the Xcode console as if Xcode was
sucking up all output from the shell program.

Deleted prefs, restarted computer and it seems to be ok… for now.
