gdb用法比较多，功能很强大，平时用到的命令大概二十条，因为一些原因，好久没用了，都生疏了。

昨天花了半天总结一下，详细信息还是在gdb中用help看。有点乱，网上好像没有思维导图,等有时间

用freemind做个,如有错误,还请指正!

基于命令行的GDB前端：gdb

基于图形的GDB前端：DDD xxgdb

基于文本的GDB前端 gdbtui|gdb -tui

一.gdb命令行参数：

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

gdb myprog -tty /dev/pts/1 [注：此处是-tty,并非有些参考书上写的-t)

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

gdb -batch -x command_file myprog :usefel!

二.进入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. 怎样不退出gdb编辑,编译源文件并重新加载编译后的? kill

   4.

   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
