My object file contents are as follows:

john:~/temp1/compile3$ objdump -r -d main.o
main.o:     file format elf64-x86-64
Disassembly of section .text:

0000000000000000 <printer2>:
0:   55                      push   %rbp
1:   48 89 e5                mov    %rsp,%rbp
4:   bf 00 00 00 00          mov    $0x0,%edi
                    5: R_X86_64_32  .rodata
9:   e8 00 00 00 00          callq  e <printer2+0xe>
                    a: R_X86_64_PC32        puts+0xfffffffffffffffc
e:   c9                      leaveq
f:   c3                      retq

0000000000000010 <main>:
10:   55                      push   %rbp
11:   48 89 e5                mov    %rsp,%rbp
14:   b8 00 00 00 00          mov    $0x0,%eax
19:   e8 00 00 00 00          callq  1e <main+0xe>
                    1a: R_X86_64_PC32       printer2+0xfffffffffffffffc
1e:   c9                      leaveq
1f:   c3                      retq

I want to replace the printer2 symbol with printer1 only in the main function and not in the printer2 function.

I tried using objcopy main.o --redefine-sym printer1=printer2, but that replaced symbols in all the functions.

Kindly help me in this regard.
