我可以使用gdb跳过一行而不必输入行号吗？ [英] Can I use gdb to skip a line without having to type line numbers?

问题描述

我知道我可以使用 jump 将程序计数器设置为特定行，所以我可以跳过一行或多行（或再次执行一些行）。我可以轻松跳过下一行而不必输入行号吗？

I know I can use jump to set the program counter to a specific line and so I can skip one or more lines (or execute some lines again). Can I easily just skip the next line without having to enter line numbers?

在运行时注释掉某些东西非常方便。 b $ b

This would be very convenient to "comment out" something at run time.

推荐答案

jump +1

跳转到下一行，即跳过当前行。您可能还希望将它与 tbreak +1 结合在跳转目标处设置临时断点。

jumps to the next line line i.e. skipping the current line. You may also want to combine it with tbreak +1 to set a temporary breakpoint at the jump target.

请参阅 http://sourceware.org/gdb/current/onlinedocs/gdb/Specify -Location.html 以获取更多用gdb表示位置的方法。

See http://sourceware.org/gdb/current/onlinedocs/gdb/Specify-Location.html for more ways of expressing locations with gdb.

请注意，如果没有断点 gdb 很可能会继续正常执行而不是跳跃。因此，如果跳跃似乎不起作用，请确保您在目的地设置了断点。

Note that without a breakpoint gdb is likely to continue execution normally instead of jumping. So if jumping doesn't seem to work, make sure you set a breakpoint at the destination.
