有没有办法让gdb在每次开始时重复相同的指令？

问题描述

我目前正在用gdb调试一个程序。
我必须反复启动gdb并执行相同的步骤：

设置一个断点，
run，
打印一个变量，
退出

有没有办法让gdb自动为我做这件事？可能是一个可以作为参数附加的脚本？

预先感谢！

解决方案

您可以通过 -x文件选项或 -ex命令选项来完成。从：

   - 命令文件
 -x文件
从文件文件执行命令。该文件的内容与源命令完全一样。请参阅命令文件。 
 -eval-command命令
 -ex命令
执行单个gdb命令。 
此选项可能会多次用于调用多个命令。它也可以根据需要与`-command'交错。 
 
 gdb -ex'target sim'-ex'load'\ 
 -x setbreakpoints -ex'run'a.out 
  

I am currently debugging a program with gdb.I have to start gdb over and over again and do the same steps:

set a breakpoint,run,print a variable,quit

Is there a way to let gdb do that automatically for me? Probably a script that could be attached as a parameter?

Thanks in advance!

解决方案

You can do it either by -x file option or by -ex command option. From Gdb manual:

-command file
-x file
Execute commands from file file. The contents of this file is evaluated exactly as the source command would. See Command files. 
-eval-command command
-ex command
Execute a single gdb command.
This option may be used multiple times to call multiple commands. It may also be interleaved with `-command' as required.

          gdb -ex 'target sim' -ex 'load' \
             -x setbreakpoints -ex 'run' a.out
