Thanks. But after setting it, disassemble main inside gdb shows in AT&T syntax, which have % or $ symbols. – Lowrance

The change is temporary, after i set and close gdb, show disassembly returns 'att' which is not correct. – Lowrance

Should be fixed now – Outwardbound

@AndreasWenzel: The older question (Permanently Change Disassembly Flavor in GDB) has a more complete answer; I edited it recently. Unfortunately I didn't dup-hammer it before editing tags, and the one original tag I kept isn't one I have a gold badge in. – Fit

@Peter I your link to my question. – Outwardbound

Answer 2

To make the change permanent you must add it to your gdb config file:

echo "set disassembly-flavor intel" >> ~/.gdbinit

Then run:

cat  ~/.gdbinit

to make sure the file has the proper content.
