EXAMPLES

       •   Gets the capture diagnostics log from the device and saves to default file in current directory (e.g.
           STM00019F3F9cap_diag.bin):

               # nvme wdc cap-diag /dev/nvme0

       •   Gets the capture diagnostics log from the device and saves to defined file in current directory (e.g.
           testSTM00019F3F9cap_diag.bin):

               # nvme wdc cap-diag /dev/nvme0 -o test

       •   Gets the capture diagnostics log from the device and saves to defined file with pathname (e.g.
           /tmp/testSTM00019F3F9cap_diag.bin):

               # nvme wdc cap-diag /dev/nvme0 -o /tmp/test
