Ruby's %x{} -- running system commands

D

Daniel Waite

The command I execute within %x{...}, if executed on the command line,
works perfectly, every time.

If I run the same command within Ruby's %x{...}, I get mixed results.
Sometimes a blank string, other times the expected output.

Why?

We can't possibly answer that without more information. Provide us =
enough information that we might be able to see the problem.
