The hrut_ps command prints process information that is not supported by the ps command in busybox, including process ID, parent process ID, priority, memory, virtual memory, etc.

Syntax

hrut_ps

Supported Information

• pid: Process ID. Each process in the operating system has a unique identifier called the process ID (pid). It is used to uniquely identify and identify a process in the system.
• ppid: Parent Process ID. It indicates the parent process that created this process.
• state: Running state.
  • I: Idle.
  • R: Running.
  • S: Sleeping.
  • D: Disk sleeping.
  • T: Stopped.
  • X: Dead.
  • Z: Zombie.
  • t: Tracing stop.
  • P: Parked.
• prio: Priority. It represents the scheduling priority of the process, usually a numerical value. A higher value indicates a higher priority, and the process may be more likely to obtain CPU time slices.
• nice: Scheduling priority. It represents the scheduling priority of the process, usually an integer value. A lower nice value indicates a higher priority, allowing the process to get CPU time more frequently.
• rt_prio: Real-time priority. It represents the priority of real-time processes. A lower value indicates a higher real-time priority.
• policy: Scheduling policy. It represents the scheduling policy of the process, usually a scheduling algorithm, such as First-In-First-Out (FIFO), Round Robin, etc.
• vsize: Virtual memory size. It represents the size of the process's virtual memory, which is the size of the virtual address space that the process can access.
• rss: Resident Set Size. It represents the current occupied physical memory size of the process, which is the actual amount of physical RAM allocated to the process.
• comm: Command name. It contains the command name of the process or the name of the executable file, which is used to identify the type or purpose of the process.
