Counter is a small process which counts upwards at a programmable interval. It can also be asked to allocate a block of memory of varying size and write alternating zeros and ones (0x55 or ASCII: 'U') across the memory range before beginning its count. This particular program was used in the debugging of memsnap. It may also be useful in a quick test for other types of debuggers and tracers.
In its own words:
$ counter -h
Usage: counter <options>
-h Print usage
-s <sec> Specify time interval in seconds
-m <ms> Specify time interval in milliseconds
-u <us> Specify time interval in microseconds
-G <GBs> Number of gigabytes of memory to allocate
-M <MBs> Number of megabytes of memory to allocate
-K <KBs> Nunber of kilobytes of memory to allocate
-f <final> Final count
