1. Info - sources, variables, functions, scope function_name, maint print symbols filename

2. Objcopy : --only-keep-debug and --add-gnu-debuglink

  info files according to GDB documentation (FIles section) do the following:
  "info files and info target are synonymous; both print the current target (see Specifying a Debugging Target), including the names of the executable and core dump files currently in use by gdb, and the files from which symbols were loaded. The command help target lists all possible targets rather than current ones.". In addition i see some names such as .bss .data .text that shuld be the names of COFF sections inside the executable, am I right?
  Great video series!! I'm planning to start studying expoitation and reversing this year and GDB will become an essential tool I think!! Thank you Vivek!!

  `info files' and `info target' are synonymous; both print the
  current target (*note Specifying a Debugging Target: Targets.),
  including the names of the executable and core dump files
  currently in use by GDB, and the files from which symbols were
  loaded. The command `help target' lists all possible targets
  rather than current ones.

  Hi Vivek, Thanks for the new addition to the series. I tweeted first two parts of video and so far I haven't received the PDF or any download link to my registered email address...Is anything I'm missing or It is not yet available for download?
  Thanks,

  Thanks Mr. Ramachandran, I really appreciate it. I like you very much as a great instructor. I think `info files` is a command that list all files that were used in debugging process.
