Linux Pmap Command – Find How Much Memory Process Use
================================================================================ ================================================================================
Pmap provide memory map of a process, The pmap command display the memory usage map of a process or multiple processes. Pmap reports information about the address space or memory usage map of a process. Pmap is actually a Sun OS command and Linux supports only very limited number of features. But it is very helpful for finding the complete address space of a process. To check [memory usage of process][1] we need PID or unique process ID of running process, we can get PID from /proc or regular commands like top or ps. Pmap 提供进程的内存映射，pmap命令显示一个或多个进程的内存状态。Pmap报告进程地址空间和内存状态信息。Pmap实际上是一个Sun OS命令，linux仅支持有限的功能。但是它还是对查看完整的进程地址空间很有帮助。检查[进程内存状态][1]我们需要PID或者运行的进程的唯一进程ID,我们可以在/proc或者常规命令比如top或ps得到它.
