How to get imge base of current setting through script in IDA pro？

Question

As a beginner I'm trying to disassemble a file with IDA Pro 6.5. I know that the image base can be find in IDA Pro manu Edit -> Segment -> Rebase program.

Now, I want to get the image base of current setting through IDC or IDAPython. Are there anyone to tell me how to write script?

Thanks in advance.

Answer 1

idaapi.get_imagebase() is your friend.

Just in case you didn't know, all the reference documentation for idapython is here

Example:

Python>hex(idaapi.get_imagebase())
0x100000L

Answer 2

idc unattended

F:\IDA_FRE_5>del outtext.txt & idag.exe -A -S.\segbase.idc c:\WINDOWS\system32\c
alc.idb & sleep 5 & type outtext.txt
Segment Base is 1001000

F:\IDA_FRE_5>type segbase.idc
#include <idc.idc>
static main ()
{
auto fpo,fullstr,segbase;
        Batch(1);
        segbase = SegStart(MinEA());
        Message("base is %x\n",segbase);
        fpo = fopen("outtext.txt","wb");
        fullstr = form("Segment Base is %x\n",segbase);
        writestr(fpo,fullstr);
        fclose(fpo);
        Exit(0);

}
