推荐答案

是否可以grep或过滤gdb中信息源的输出?

Is it possible to grep or filter the output of info sources in gdb?

不.这可能被认为是一个错误:info shared使用可选的正则表达式来过滤共享库，但info sources则不是.

No. This could be considered a bug: info shared takes an optional regex to filter shared libraries, but info sources does not.

解决方法:

(gdb) set logging on  # GDB output will now be copied into gdb.txt
(gdb) info sources
(gdb) set logging off
(gdb) shell grep bob.cpp gdb.txt
(gdb) shell rm gdb.txt

如果您需要经常执行此操作，则可以将上述命令放入用户定义的命令.

If you need to do this often, you could put above commands into a user-defined command.
