+.TH proc_pid_statm 5 2023-08-15 "Linux man-pages 6.06"
+.SH NAME
+/proc/pid/statm \- memory usage information
+.SH DESCRIPTION
+.TP
+.IR /proc/ pid /statm
+Provides information about memory usage, measured in pages.
+The columns are:
+.IP
+.in +4n
+.EX
+size (1) total program size
+ (same as VmSize in \fI/proc/\fPpid\fI/status\fP)
+resident (2) resident set size
+ (inaccurate; same as VmRSS in \fI/proc/\fPpid\fI/status\fP)
+shared (3) number of resident shared pages
+ (i.e., backed by a file)
+ (inaccurate; same as RssFile+RssShmem in
+ \fI/proc/\fPpid\fI/status\fP)
+text (4) text (code)
+.\" (not including libs; broken, includes data segment)
+lib (5) library (unused since Linux 2.6; always 0)
+data (6) data + stack
+.\" (including libs; broken, includes library text)
+dt (7) dirty pages (unused since Linux 2.6; always 0)
+.EE
+.in
+.IP
+.\" See SPLIT_RSS_COUNTING in the kernel.
+.\" Inaccuracy is bounded by TASK_RSS_EVENTS_THRESH.
+Some of these values are inaccurate because
+of a kernel-internal scalability optimization.
+If accurate values are required, use
+.IR /proc/ pid /smaps
+or
+.IR /proc/ pid /smaps_rollup
+instead, which are much slower but provide accurate, detailed information.
