2. hrut_ps
The hrut_ps command prints process status information not supported by BusyBox's ps command, including process ID, parent process ID, priority, memory usage, virtual memory, and more.
Grammar explanation
xxxxxxxxxxhrut_psSupported Information
pid: Process ID. Each process in the operating system has a unique identifier called the process ID (pid), which is used to uniquely identify and reference a process within the system.
ppid: Parent Process ID. This indicates the parent process that created the current process.
state: Process state.
I: Idle.R: Running.S: Sleeping.D: Disk sleeping (uninterruptible sleep).T: Stopped.X: Dead.Z: Zombie.t: Tracing stop.P: Parked.
prio: Priority. Represents the scheduling priority of the process, usually expressed as a numeric value. A higher number typically indicates higher priority, making the process more likely to receive CPU time slices.
nice: Nice value. Represents the scheduling priority as an integer. A lower nice value indicates higher priority, allowing the process to obtain CPU time more frequently.
rt_prio: Real-time priority. Indicates the priority of real-time processes; a lower value signifies higher real-time priority.
policy: Scheduling policy. Specifies the scheduling policy used for the process, typically a scheduling algorithm such as First-In-First-Out (FIFO), Round Robin (RR), etc.
vsize: Virtual memory size. Represents the size of the virtual memory address space accessible to the process.
rss: Resident Set Size (physical memory usage). Indicates the amount of physical RAM currently allocated and used by the process.
comm: Command name. Contains the name of the command or executable file associated with the process, used to identify the process type or purpose.
3. hrut_somstatus
The hrut_somstatus command retrieves temperature sensor readings, CPU/BPU operating frequencies, and BPU load.

4. rdkos_info
The rdkos_info command is used to collect, in one go, software and hardware versions of the RDK system, a list of loaded drivers, installed RDK software packages, and the latest system logs, enabling users to quickly obtain the current system status information.
Grammar explanation
xxxxxxxxxxsudo rdkos_info [options]Options
All options are optional. If run without any options,
rdkos_infodefaults to the concise output mode.-b: Basic output mode; system logs will not be collected.-s: Concise output mode (default); outputs the latest 30 lines of system logs.-d: Detailed output mode; outputs the latest 300 lines of system logs.-v: Display version information.-h: Display help information.

6.devmem
devmem is a command in BusyBox. It can read from and write to hardware registers by using the mmap function to map device memory into user space via the mmap method of the /dev/mem driver, thereby enabling read/write operations on physical addresses.
Grammar explanation
xxxxxxxxxxdevmem ADDRESS [WIDTH [VALUE]]Read/write from physical addressADDRESS Address to act uponWIDTH Width (8/16/...)VALUE Data to be written- ADDRESS: The physical address on which to perform the operation. This is a required parameter specifying the address to read from or write to.
- WIDTH: An optional parameter indicating the data width. It can be specified as 8, 16, or 32, defining the bit-width of the data to read or write. If omitted, it defaults to 32 bits.
- VALUE: An optional parameter representing the data value to write. If
WIDTHis provided,VALUEmust match the specified width. IfVALUEis omitted, the command performs a read operation.
