debugging - 如何搜索在 GDB 的 TUI 模式下打开的文件

Question

我有一个在 gdb 的 TUI 模式下打开的几千行的文件。我想在文件中搜索一个变量，这可能吗？因为文件很长，我真的很想避免手动搜索这个词。

Answer 1

手册中没有定义 TUI 特定的搜索命令。 gdb 是调试器，而不是代码导航工具(使用 ctags/cscope/lxr/source navigator；或使用 IDE 与调试器和代码导航器)。

尝试使用 gdb(非 TUI)命令，但它仅适用于下一个位置(我在这里看不到“下一个搜索”):

There are two commands for searching through the current source file for a regular expression.

forward-search regexp
search regexp

The command ‘forward-search regexp’ checks each line, starting with the one following the last line listed, for a match for regexp. It lists the line that is found. You can use the synonym ‘search regexp’ or abbreviate the command name as fo.

reverse-search regexp

The command ‘reverse-search regexp’ checks each line, starting with the one before the last line listed and going backward, for a match for regexp. It lists the line that is found. You can abbreviate this command as rev.

您也可以使用 list更改 TUI 源窗口中显示的行的命令 - https://sourceware.org/gdb/onlinedocs/gdb/List.html#List
