pipebench is a utility that shows the status and a benchmark of piped commands.
Pipebench measures the speed of a pipe, by sitting in the middle passing the data along to the next process. Works on at least Linux, OpenBSD, NetBSD, Solaris and x86, Alpha, HPPA, Sparc and Sparc64.
Just type 'make' to compile.
Type 'make install' to have pipebench be installed in /usr/local/bin
