-|`-s`|Provide short summary, one line per device|
-|`-o`|List supported device controls and options|
-|`-c`|Provide calibration (Intrinsic/Extrinsic) information|
-| None| List supported streaming modes|
+|`-s`|Provide a one-line summary, one line per device|
+|`-S`|Extends `-s` by providing a short summary for each device|
+|`-o`|List supported device controls, options and streaming modes|
+|`-c`|Provide calibration (Intrinsic/Extrinsic) and steraming modes information|
+|`-p`|Enumerate streams contained in ROSBag record file. Usage `-p <rosbag_full_path>`|
+| None| The default mode. Equivalent to `-S` plus the list of all the supported streaming profiles|
+
+The options `-o`, `-c` `-p` are additive and can concatenated:
+`rs-enumerate-devices -o -c -p rosbag.rec` - will print the camera info, streaming modes,
+supported option and the calibration info both for the live cameras and the prerecorded `rosbag.rec` file.
+
+The options `-S`, `-s` are restrictive and therefore incompatible with `-o` and `-c`,
+but still can be used with `-p <file_name>`.
