Our customer support wiki runs on an internal host (ip:192.168.1.100:300, hostname a-node100.:300) and it is behind the nginx reverse proxy server. However, our Apache server end up displaying internal server name http://a-node100.:300/, which results into an unexpected redirection and timeouts as http://a-node100.:300/ is not accessible over the Internet. How do I force nginx or apache to use the base URL of our server (http://support.example.com/wiki/)?

A. Bash shell (and many other modern UNIX shell) supports the concept of I/O redirection It allows you to redirect standard output (screen), standard error and standard input (keyboard) using the following syntax.
command > output.file
command < input.file
command >& error-n-output.file
So to redirect output of your own C program just enter:
$ ./myprogr > output.txt
$ cat output.txt
