如何在日志文件中包含GDB命令? [英] How to include GDB commands in logging file?

问题描述

我要执行的文件中有一些gdb命令.我还希望运行命令并将输出记录到文件中.

I have some gdb commands in a file that I want to execute. I also want the commands run and the output to be logged to a file.

我在名为gdb.in的文件中编写了以下gdb脚本.

I wrote the following gdb script in a file named gdb.in.

set logging file gdb.out
set logging on
echo hi\n
printf "bye\n"
quit

但是，如果执行此gdb脚本，则只能看到记录到gdb.out的输出.我看不到执行的命令.

However, if I execute this gdb script, I can only see the output logged to gdb.out. I don't see the commands executed.

$ gdb -x gdb.in

hi
bye
$ cat gdb.out
hi
bye

据我所记得，几年前，我找到了一种记录命令的方法.以前，每个命令都以+符号作为前缀出现在日志文件中.例如，几年前我就能得到这样的输出.

As far as I can remember, a few years ago, I found a way to log the commands. Each command used to appear in the log file with a +-sign as a prefix. For example, I was able to get an output like this a few years ago.

+ echo hi\n
hi
+ printf "bye\n"
bye
+ quit

但是我无法回忆起我为获得这样的输出所做的事情.搜索网络也无济于事.我在如何将整个GDB会话转储到文件中(包括我键入的命令及其输出)遇到了这个问题?那里的答案不能捕获在日志文件中执行的命令.

But I am unable to recall what I did to get such an output. Searching the web also didn't help me. I came across this question at How to dump the entire GDB session to a file, including commands I type and their output? but the answers there don't capture the commands executed in the log file.

推荐答案

set trace-commands on:在执行命令之前先回显屏幕中的命令.将此与日志一起使用，以将命令写入文件.

set trace-commands on: echos the command in screen before executing it. Use this along with logging to get the command written to file.
