linux中的strings命令简介
在linux下搞软件开发的朋友， 几乎没有不知道strings命令的。我们先用man strings来看看：
1 #include <stdio.h> 2 3 int add(int x, int y) 4 { 5 return x + y; 6 } 7 8 int main() 9 { 10 int a = 1; 11 int b = 2; 12 int c = add(a, b); 13 printf("oh, my dear, c is %d\n", c); 14 15 return 0; 16 }
我们来看看strings test.c的结果：
1 [taoge@localhost learn_c]$ strings test.c 2 #include <stdio.h> 3 int add(int x, int y) 4 return x + y; 5 int main() 6 int a = 1; 7 int b = 2; 8 int c = add(a, b); 9 printf("oh, my dear, c is %d\n", c); 10 return 0; 11 [taoge@localhost learn_c]$
1 [taoge@localhost learn_c]$ gcc test.c 2 [taoge@localhost learn_c]$ strings a.out 3 /lib/ld-linux.so.2 4 =$TsU 5 __gmon_start__ 6 libc.so.6 7 _IO_stdin_used 8 printf 9 __libc_start_main 10 GLIBC_2.0 11 PTRh 12 [^_] 13 oh, my dear, c is %d 14 [taoge@localhost learn_c]$
1 void print();
1 #include <stdio.h> 2 #include "xxx.h" 3 4 void print() 5 { 6 printf("rainy days\n"); 7 }
然后， 我们来看看怎么制作静态、动态库吧（在后续博文中会继续详细介绍）：
1 [taoge@localhost learn_strings]$ ls 2 xxx.c xxx.h 3 [taoge@localhost learn_strings]$ gcc -c xxx.c 4 [taoge@localhost learn_strings]$ ar rcs libxxx.a xxx.o 5 [taoge@localhost learn_strings]$ gcc -shared -fPIC -o libxxx.so xxx.o 6 [taoge@localhost learn_strings]$ ls 7 libxxx.a libxxx.so xxx.c xxx.h xxx.o 8 [taoge@localhost learn_strings]$ strings xxx.o 9 rainy days 10 [taoge@localhost learn_strings]$ strings libxxx.a 11 !<arch> 12 / 1437887339 0 0 0 14 ` 13 Rprint 14 xxx.o/ 1437887333 501 502 100664 848 ` 15 rainy days 16 GCC: (GNU) 4.4.4 20100726 (Red Hat 4.4.4-13) 17 .symtab 18 .strtab 19 .shstrtab 20 .rel.text 21 .data 22 .bss 23 .rodata 24 .comment 25 .note.GNU-stack 26 xxx.c 27 print 28 puts 29 [taoge@localhost learn_strings]$ 30 [taoge@localhost learn_strings]$ 31 [taoge@localhost learn_strings]$ strings libxxx.so 32 __gmon_start__ 33 _init 34 _fini 35 __cxa_finalize 36 _Jv_RegisterClasses 37 print 38 puts 39 libc.so.6 40 _edata 41 __bss_start 42 _end 43 GLIBC_2.1.3 44 GLIBC_2.0 45 rainy days 46 [taoge@localhost learn_strings]$
1 [taoge@localhost learn_c]$ strings -f * | grep "my dear" 2 a.out: oh, my dear, c is %d 3 test.c: printf("oh, my dear, c is %d\n", c); 4 [taoge@localhost learn_c]$
