    -d tmpdir       Directory where temporary files will be created.
    -f cmdfile      Execute user defined list of testcases.
    -h              Help. Prints all available options.
    -i # (in Mb)    Run LTP with a _minimum_ IO load of # megabytes in background.
    -l logfile      Log results of test in a logfile.
    -m # (in Mb)    Run LTP with a _minimum_ memory load of # megabytes in background.

    -n              Run LTP with network traffic in background.
    -p              Human readable format logfiles. 
    -q              Print less verbose output to screen.
    -r ltproot      Fully qualified path where testsuite is installed.
    -t duration     Execute the testsuite for given duration. Examples:
                      -t 60s = 60 seconds
                      -t 45m = 45 minutes

                      -t 2d  = 2 days
                     
    -x instances    Run multiple instances of this testsuite.

    example: ./${0##*/} -i 1024 -m 128 -p -q  -l /tmp/resultlog.$$ -d ${PWD}
