Dproc

Dproc is a command-line utility found on some Unix-like operating systems, particularly those derived from System V. Its primary function is to display information about active processes on the system. Unlike more common tools like `ps`, `dproc` often presents process information in a more structured and perhaps simplified format, making it potentially easier for scripting or quick status checks. The exact output and capabilities can vary depending on the specific implementation and operating system. Historically, it was part of the System V process accounting and management utilities, designed to provide a detailed view of system resources consumed by each running process. Users typically invoke `dproc` without any arguments to see a list of all processes, or with specific options to filter or sort the output. Some versions might allow filtering by user, process ID, or other process attributes. The information displayed can include process ID, parent process ID, user ID, CPU time consumed, memory usage, and the command line that initiated the process. Dproc's utility lies in its ability to offer a focused view of process data, often complementing or providing an alternative to the more widely adopted `ps` command. Its presence is less common on modern Linux distributions compared to `ps` or `top`.
