How do you pass a command on to another command?
Pass output of command1 through xargs using substitution (the braces) to command2 . If command1 is find be sure to use -print0 and add -0 to xargs for null terminated strings and xargs will call command2 for each thing found. The first task is to extract the rate from that line.
