I have a test script that works on linux but fails to work properly on Windows.
It runs a command, captures the standard out and compares it to a reference
file.
On linux everything works 99% of the time (issue with '=' or '--' in a
parameter argument - later question). On windows, the execution of the test
program fails with;
"The process cannot access the file because it is being used by
another process"
Any suggestions would be welcomed. As a fallback I will need to create a
windows batch file.
