I'm using iozone3 for tesing, on Xamin (an Debian-based OS). When I enter iozone command, for example iozone -Rab output.xls, the test runs successfully.But after running the test (after displaying this message: iozone test complete.). Instead of generating the excel file, iozone returns the results in shell.Why doesn't it generate an excel file?
why doesn't iozone generate output file?

iozone -Rab output.wks will do both.  The command will output the flat ascii formatted results for possible import by Excel ( space and tab delimited ) as well as generating the output.wks file, which is already in BIFF (Binary Interchange File Format).The output.wks file can be opened directly with Excel, and permits one to skipimporting the flat ascii from standard out.
