這篇文章主要介紹了linux中pmap 指令詳解,需要的朋友可以參考下
透過查看幫助,回傳瞭如下資訊:
Usage: pmap [options] pid [pid ...] Options: -x, --extended show details -X show even more details WARNING: format changes according to /proc/PID/smaps -XX show everything the kernel provides -c, --read-rc read the default rc -C, --read-rc-from=<file> read the rc from file -n, --create-rc create new default rc -N, --create-rc-to=<file> create new rc to file NOTE: pid arguments are not allowed with -n, -N -d, --device show the device format -q, --quiet do not display header and footer -p, --show-path show path in the mapping -A, --range=<low>[,<high>] limit results to the given range -h, --help display this help and exit -V, --version output version information and exit For more details see pmap(1).
接著列出某個進程(PID:8868)的資訊時如下:
pmap -x 8868 Address Kbytes RSS Dirty Mode Mapping 00007f789ec2d000 1668 1384 0 r-x-- libc-2.19.so 00007f789edce000 2048 0 0 ----- libc-2.19.so 00007f789efce000 16 16 16 r---- libc-2.19.so 00007f789efd2000 8 8 8 rw--- libc-2.19.so 00000000020e0000 4008 4008 4008 rw--- [ anon ] 00007f787c000000 132 24 24 rw--- [ anon ] 00007f787c021000 65404 0 0 ----- [ anon ] 00007f7880000000 132 12 12 rw--- [ anon ] 00007f7880021000 65404 0 0 ----- [ anon ] 00007f7884000000 148 92 92 rw--- [ anon ] 00007f7884025000 65388 0 0 ----- [ anon ]
以上列表項目的意義如下:
Address: 內存分配位址
Kbytes: 實際分配的記憶體大小
RSS: 程式實際佔用的記憶體大小
Mapping: 分配此記憶體的模組的名稱
