Hi Don...

Thanks for the info, it is all logged down in the old grey matter for future use.

As for while(1) I assumed that it was filling up a buffer of some kind but never guessed that it was the pipe, | , that it was filling up.
Clever idea that one. (I love lateral thinking.)

I assumed also - like in Python - that while(1) is the equivalent of while(True): . Both (1) and (True) are valid in Python even in Python's latest guise.
Python has not deprecated the (1) which goes back to the start of the Python project.

LBNL, I got the idea of my original ugly code from the WWW from many sources and no-one considered that '/dev/urandom' was NOT in the POSIX specifications. Even the WWW can give answers that are effectively false, so......

......I now consider this thread _solved_ and thanks again Don, you saved the day.

PYTHON-COVERAGE(1)					      General Commands Manual						PYTHON-COVERAGE(1)

NAME
python-coverage - measure code coverage of Python program execution SYNOPSIS
python-coverage -x module.py [ARG...] python-coverage -e python-coverage -r [-m] python-coverage -a [file...] DESCRIPTION
python-coverage executes a Python program and measures which of its statements are executed and which are not. It stores the information in the file .coverage in the current working directory. OPTIONS
-e Erase the .coverage file. -x Execute a Python module, giving it the remaining command line arguments. -r Produce a coverage report. -m With -r, show the line numbers that were missed by the execution. -a Annotate source files. For each source file foo, produce foo,cover, with executed lines prefixed by ">" and non-executed by "!". --help Produce a help summary. It might be more helpful than this manual page. AUTHOR
The python-coverage command is a one-line Python script which calls the coverage.py Python module to do all the work. The module was rigi- nally developed by Gareth Rees, and is now developed by Ned Batchelder. The module's home page is http://www.nedbatchelder.com/code/modules/coverage.html. This manual page was cobbled together by Lars Wirzenius for Debian, by copy-pasting from the help texts from the module. PYTHON-COVERAGE(1)
