Question

我有一个c / c ++应用程序的核心转储。我是编程的新手，所以这个问题可能听起来很愚蠢。是否有一些我可以编写脚本来使用gdb来分析核心转储？

Answer 1

是的，只需编写您想要的任何内容。例如：

gdb \
   -ex "set pagination 0" \
   -ex "thread apply all bt" \
   -batch ${EXECUTABLE_FILE} ${CORE_FILE}

Answer 2

按如下所示使用-x选项

$ cat gdb.cmds
set confirm off
set height 0
cd /homes/syrajendra
file dump
core dump.core
set solib-search-path "/lib"
bt
printf "\n"
quit

$ gdb -x gdb.cmds
