pmap

PMAP(1) 							Linux User's Manual							   PMAP(1)

NAME

       pmap - display information about process memory mappings

SYNOPSIS

       pmap [ -d | -q | -h | -V | -A low,high ] pid

DESCRIPTION

       pmap(1) displays information about a process's memory mappings, such as its stack, data segment, mapped files, and so on.

       The pmap(1) utility will show, for each mapping of a given process, the starting byte address in the process's address space, the size, the
       RSS (size of the mapping in physical memory), the amount of dirty pages, the permission, the device node, the offset, and the file  backing
       the mapping, if any.

       As  the	last  line  of	output,  the  pmap(1)  utility	will  tally  up  the  total size of all mappings as well as show the total size of
       writable/private mappings and of shared mappings.

OPTIONS

       d, --device
	      Display major and minor device numbers.

       A, --limit=low,high
	      Limit results to the given range.

       q, --quiet
	      Hide header and memory statistics.

       h, --help
	      Show pmap usage.

       V, --version
	      Display version information.

FILES

       /proc/pid/maps and /proc/pid/smaps -- memory mapping information
