PMAP(1)

NAME
pmap - display information about process memory mappings

SYNOPSIS
pmap [ -d | -q | -h | -V ] 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 permission, the device node, the offset, and the file backing the mapping. If the mapping is anonymous, no file is specified and that field is blank.

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.
