.SH NAME
-pmap \- report memory map of a process
+pmap \- display information about process memory mappings
.SH SYNOPSIS
-.nf
-pmap [ -x | -d ] [ -q ] pids...
-pmap -V
-.fi
+.BI "pmap [ \-d | \-q | \-h | \-V | \-A\ low,high ] " pid
.SH DESCRIPTION
-The pmap command reports the memory map of a process or processes.
-
-.SH "GENERAL OPTIONS"
-.TS
-l l l.
--x extended Show the extended format.
--d device Show the device format.
--q quiet Do not display some header/footer lines.
--V show version Displays version of program.
-.TE
+.BR pmap (1)
+displays information about a process's memory mappings, such as its stack,
+data segment, mapped files, and so on.
+.P
+The
+.BR 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.
+.P
+As the last line of output, the
+.BR 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.
+
+.SH OPTIONS
+.TP
+.B\-d, \-\^\-device
+Display major and minor device numbers.
+.TP
+.B\-A, \-\-limit=low,high
+Limit results to the given range.
+.TP
+.B\-q, \-\^\-quiet
+Hide header and memory statistics.
+.TP
+.B\-h, \-\^\-help
+Show pmap usage.
+.TP
+.B\-V, \-\^\-version
+Display version information.
+
+.SH FILES
+.IR /proc/pid/maps " and
+.IR /proc/pid/smaps " \-\- memory mapping information"
.SH "SEE ALSO"
-ps(1) pgrep(1)
+.BR ps (1),
+.BR top (1),
+.BR free (1),
+.BR vmstat (1)
-.SH STANDARDS
-No standards apply, but pmap looks an awful lot like a SunOS command.
+.SH AUTHORS
+Written by Chris Rivera.
