[Linux x86] - copy a file to another directory

[xor]

Code: (asm) [Select]

.section .data
        .globl _start

_start:
        nop
        jmp  loadstring

main:
        xor  %eax, %eax
       
        pop  %ebx          # load our string
        movb %al, 7(%ebx)  # terminate string
        movb %al, 15(%ebx)
        movb %al, 23(%ebx)
        mov  %ebx, 24(%ebx)

loadstring:
        call main
        .ascii "/bin/cpS/bin/shS/tmp/shN"

First part and second part of the .ascii string are which file to be copied, and last part is where to copy it to. The S and N are just for padding and string termination.

Obviously no one noticed, but this ASM is incomplete. It prepares the command line arguments for moving a file, but doesn't actually execute the syscall to start the move. Lets see if any of you can complete it.
