gdb用法比較多，功能很強大，平時用到的命令大概二十條，因為一些原因，好久沒用了，都生疏了。

昨天花了半天總結一下，詳細信息還是在gdb中用help看。有點亂，網(wǎng)上好像沒有思維導圖,等有時間

用freemind做個,如有錯誤,還請指正!

========================================================

基于命令行的GDB前端：gdb

基于圖形的GDB前端：DDD xxgdb

基于文本的GDB前端 gdbtui|gdb -tui

一.gdb命令行參數(shù)：

gdb (gdb arguments)--args myprog (myprog arguments)

gdb myprog -tty /dev/pts/1 [注：此處是-tty,并非有些參考書上寫的-t)

gdb -q(-s)   :do not display the gdb and GPL information

gdb -batch -x command_file myprog :usefel!

二.進入gdb后的命令：

   1. file : load the execute file if not load in the command line

   2. shell shell_command Execute the rest of the line as a shell command.With no arguments, run an inferior shell.

   3. 怎樣不退出gdb編輯,編譯源文件并重新加載編譯后的? kill

   4.

   5.

   6. l(ist) [from,to] repeat to display the whole source code

   7.

   8. b(reak)   (num or function) if condition

   9. condition bp_number [expression]    if u have set bp in the desired position, add or change the the bk condition

 10.                                     To delete a break condition,do not use expression

 11. watch

 12. watch expression     stop the program when the value of expression changes.

 13. rwatch expression    stop the program whenever the program reads the value of any object involved in the evaluation of ex                     pression.

 14. awatch expression    stop the program whenever the program reads or modifies the value of any object involved in the eval                     uation of expression.

 15. delete

 16. enable

 17. disable

 18. ignore N n        ignore bp N n times

 19.

 20. r(un)

 21. s(tep) [lines] finish

 22. n(ext) [lines]

 23. c(ontinue) [passes]        pass the bp passes times before stop the program

 24.

 25. display

 26. p(rint)[/format] [expression]

 27. /format=/d u x o t c|a f

 28. x[/nfu] [address]

 29. /nfu

 30. n: how many units,default is one

 31. u the size of one unit the value is b h w g

 32. f = the print format in additional to s and i

 33. f = d u x o t f c s a i

 34. ptyp(=whatis)

 35.

 36.

 37. bt(backtrace)(=where)

 38. frame display and change the current frame

 42. set args    set env VAR1=test set variable
