我想在一個文件中執行一些gdb命令。我也想讓命令運行並將輸出記錄到文件中。如何在記錄文件中包含GDB命令？
我在一個名爲gdb.in的文件中寫了下面的gdb腳本。
set logging file gdb.out
set logging on
echo hi\n
printf "bye\n"
quit
但是，如果我執行這個gdb腳本，我只能看到輸出記錄到gdb.out。我看不到執行的命令。
$ gdb -x gdb.in

hi
bye
$ cat gdb.out
hi
bye
據我記得，幾年前，我找到了一種記錄命令的方法。用於出現在日誌文件中的每個命令都以+作爲前綴。例如，幾年前我能夠得到這樣的輸出。
+ echo hi\n
hi
+ printf "bye\n"
bye
+ quit
但我無法回想起我做了什麼來獲得這樣的輸出。搜索網絡也沒有幫助我。我在How to dump the entire GDB session to a file, including commands I type and their output?處遇到了這個問題，但那裏的答案沒有捕獲在日誌文件中執行的命令。
