Subject: How do I dup file descriptors in ruby?  (diverting STDERR)

Hello,

How would I do the equivalent to the following
Korn/Bourne code in ruby?


######################################
# Save STDERR default
exec 3>&2
# Send STDERR to a file
exec 2> logfile.text


# Do stuff that might have error messages in it
# Error will go to logfile.text instead of the
# terminal.
/bin/ls non_existent_file
echo "hello world" 1>&2
run_non_existent_command


# Restore STDERR
exec 2>&3
# Close extra file descriptor
exec 3>&-
# Error messages will now go to the terminal
######################################



Thank you for any help you can give,
Richard Ryan
