用于顯示elf格式文件的信息
readelf命令 用來顯示一個(gè)或者多個(gè)elf格式的目標(biāo)文件的信息,可以通過它的選項(xiàng)來控制顯示哪些信息。這里的elf-file(s)就表示那些被檢查的文件??梢灾С?2位,64位的elf格式文件,也支持包含elf文件的文檔(這里一般指的是使用ar命令將一些elf文件打包之后生成的例如lib*.a之類的“靜態(tài)庫”文件)。
這個(gè)程序和objdump提供的功能類似,但是它顯示的信息更為具體,并且它不依賴BFD庫(BFD庫是一個(gè)GNU項(xiàng)目,它的目標(biāo)就是希望通過一種統(tǒng)一的接口來處理不同的目標(biāo)文件),所以即使BFD庫有什么bug存在的話也不會(huì)影響到readelf程序。
運(yùn)行readelf的時(shí)候,除了-v和-H之外,其它的選項(xiàng)必須有一個(gè)被指定。
種類型的ELF文件:
ELF文件作用:
ELF文件參與程序的連接(建立一個(gè)程序)和程序的執(zhí)行(運(yùn)行一個(gè)程序),所以可以從不同的角度來看待elf格式的文件:
ELF文件總體組成:
elf文件頭描述elf文件的總體信息。包括:系統(tǒng)相關(guān),類型相關(guān),加載相關(guān),鏈接相關(guān)。
-a
--all 顯示全部信息,等價(jià)于 -h -l -S -s -r -d -V -A -I.
-h
--file-header 顯示elf文件開始的文件頭信息.
-l
--program-headers
--segments 顯示程序頭(段頭)信息(如果有的話)。
-S
--section-headers
--sections 顯示節(jié)頭信息(如果有的話)。
-g
--section-groups 顯示節(jié)組信息(如果有的話)。
-t
--section-details 顯示節(jié)的詳細(xì)信息(-S的)。
-s
--syms
--symbols 顯示符號(hào)表段中的項(xiàng)(如果有的話)。
-e
--headers 顯示全部頭信息,等價(jià)于: -h -l -S
-n
--notes 顯示note段(內(nèi)核注釋)的信息。
-r
--relocs 顯示可重定位段的信息。
-u
--unwind 顯示unwind段信息。當(dāng)前只支持IA64 ELF的unwind段信息。
-d
--dynamic 顯示動(dòng)態(tài)段的信息。
-V
--version-info 顯示版本段的信息。
-A
--arch-specific 顯示CPU構(gòu)架信息。
-D
--use-dynamic 使用動(dòng)態(tài)段中的符號(hào)表顯示符號(hào),而不是使用符號(hào)段。
-x <number or name>
--hex-dump=<number or name> 以16進(jìn)制方式顯示指定段內(nèi)內(nèi)容。number指定段表中段的索引,或字符串指定文件中的段名。
-w[liaprmfFsoR] or
--debug-dump[=line,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges] 顯示調(diào)試段中指定的內(nèi)容。
-I
--histogram 顯示符號(hào)的時(shí)候,顯示bucket list長度的柱狀圖。
-v
--version 顯示readelf的版本信息。
-H
--help 顯示readelf所支持的命令行選項(xiàng)。
-W
--wide 寬行輸出。
@file 可以將選項(xiàng)集中到一個(gè)文件中,然后使用這個(gè)@file選項(xiàng)載入。
先給出如下例子:
1.對(duì)于可執(zhí)行文件形式的elf格式文件:
1)查看可執(zhí)行程序的源代碼如下:
root@localhost [test]$ cat main.cpp
#include <iostream>
using std::cout;
using std::endl;
void my_print();
int main(int argc, char *argv[])
{
my_print();
cout<<"hello!"<<endl;
return 0;
}
void my_print()
{
cout<<"print!"<<endl;
}
2)編譯如下:
[root@localhost test]$ g++ main.cpp -o main
[root@localhost test]$ g++ -g main.cpp -o main.debug
3)編譯之后,查看生成的文件:
[root@localhost test]$ ls -l
總計(jì) 64
-rwxr-xr-x 1 quietheart quietheart 6700 07-07 18:04 main
-rw-r--r-- 1 quietheart quietheart 201 07-07 18:02 main.cpp
-rwxr-xr-x 1 quietheart quietheart 38932 07-07 18:04 main.debug
這里,main.debug是帶有調(diào)試信息的可執(zhí)行文件,main是一般的可執(zhí)行文件。
2.對(duì)于庫文件形式的elf格式文件:
1)查看庫的源代碼如下:
//myfile.h
#ifndef __MYFILE_H
#define __MYFILE_H
void printInfo();
#endif
//myfile.cpp
#include "myfile.h"
#include <iostream>
using std::cout;
using std::endl;
void printInfo()
{
cout<<"hello"<<endl;
}
2)編譯如下:
[root@localhost test]$ g++ -c myfile.cpp
[root@localhost test]$ g++ -shared -fPCI -o libmy.so myfile.o
[root@localhost test]$ ar -r libmy.a myfile.o
ar: creating libmy.a
3)編譯之后,查看生成的文件:
[root@localhost test]$ ls -l
總計(jì) 44
-rw-r--r-- 1 quietheart quietheart 2154 07-08 16:14 libmy.a
-rwxr-xr-x 1 quietheart quietheart 5707 07-08 16:08 libmy.so
-rwxr-xr-x 1 quietheart quietheart 117 07-08 16:06 myfile.cpp
-rwxr-xr-x 1 quietheart quietheart 63 07-08 16:08 myfile.h
-rw-r--r-- 1 quietheart quietheart 2004 07-08 16:08 myfile.o
libmy.a libmy.so myfile.cpp myfile.h myfile.o
這里,分別生成目標(biāo)文件myfile.o,共享庫文件libmy.so,和靜態(tài)庫文件libmy.a。
基于以上可執(zhí)行文件和庫,這里給出一些常用的命令。
