I want debug a ELF format file under Linux, is there any tool under Linux can support set breakpoint at 'Memory, access' just like in ollydbg?

I check edb, but seems no this function.

Wow, I didn't know EDB, thanks for the tip....

Unfortunately, anyway, the best debugger is yet the command-line SDB, and it can put memory access breakpoints...
look at
http://stackoverflow.com/questions/58851/can-i-set-a-breakpoint-on-memory-access-in-gdb ("http://stackoverflow.com/questions/58851/can-i-set-a-breakpoint-on-memory-access-in-gdb")

gdb is capable of setting hardware breakpoint 2939

linux vs olly lool

This OS can not be debugging.

Dear Bilbo,

Maybe I almost near what I want to do with your given. Here still an issue before I can try this solution, the file(file B) I want to debug is called by another file(file A), so I modify the entrance of file B to "EFEB" to make the debug can break at the entrance of file B. With edb I can modify "EFBE" back to source code and go on debug. Would you help check how to do this in gdb? Many thanks.

Dear blabberer,

Thanks for your guide, would you also help to check my issue at #5 on how to modify EFBE back to the source code with gdb? Many thanks.

use set {type} <address> = value notation
like
set {unsigned char } 401000 = \xeb
set {char [200] } 403000 = "hello i am coming commming commmmming"
set { int } 401337 = 0x1337

Dear blabberer,

Wow, it works, I can debug whant I want to debug now, thank you so much for your guidance and kind help.
