I have created simple code to test using lldb . This is the first time i am using lldb and i am familiar with gdb. while i am trying to disassemble the unix executable file its not working any commands i should use . Or i should try other , if so can you provide me a list of disassembler,decompiler and debugger for unix and windows 64bit processors which supports scripting too. I have searched for them but could't find. can you suggest me list of good disassemblers.
What are you trying, exactly? Here are some disassemble commands for use within LLDB:
disassemble --frame: Disassemble the currently running function.
disassemble -a 0x1234: Disassemble the function containing the address
disassemble -n _foo: Disassemble the function called "
help disassemble to learn more.
As for a list of good disassemblers on various platforms, it depends whether you have a lot of disposable income or not. IDA Pro is the best but it costs around $1000. If that's prohibitive, Google can help you find lists of free and cheap tools.
