The command "pmap ${pid}" is used to display the memory map of a specific process identified by its process ID (pid).
Here's a breakdown of the command:
- "pmap": It is the name of the command itself, which stands for "process map". It is commonly found on Unix-like operating systems.
- "${pid}": This is a placeholder for the process ID for which you want to view the memory map. In a proper usage scenario, you would replace "${pid}" with the actual process ID number. The process ID is a unique identifier assigned to each running process on a system.
When you execute the command, it will display information about the memory usage and mapping of the specified process. This information typically includes the virtual memory addresses used by the process, the permissions associated with each memory region, and the file or device where the memory is backed up.
The "pmap" command is primarily used for diagnosing memory-related issues or analyzing the memory footprint of a particular process. It can help identify memory leaks, determine the memory usage of different sections of a program, and provide insights into the memory mapping of a process.
