nagios.cmd is a pipe, not an ordinary file and the contents cannot be  
overwritten as such - whatever gets written into the pipe will be  
read out of the pipe by the controlling binary in the same order.

If you cat the pipe then the contents will be lost to nagios, as when  
items are read from the pipe they are automatically removed from it.

Pipes have the first letter as a 'p' on 'ls -l'.
