dbx is a source-level debugger for z/OS® UNIX System Services. It provides an environment to debug and run C and C++ programs, as well as performing machine level debug. You can carry out operations such as the following: Examine object files; Run a …

The three most common ways to start a debug session with the dbx program are: Running the dbx command on a specified object file; Using the -r flag to run the dbx command on a program that ends abnormally; Using the -a flag to run the dbx command on a process that is already in progress; When the dbx command is started, it checks for a .dbxinit ...

dbx is a source-level debugger found primarily on Solaris, AIX, IRIX, Tru64 UNIX, Linux and BSD operating systems. It provides symbolic debugging for programs written in C, C++, Fortran, Pascal and Java. Useful features include stepping through programs one source line or machine instruction at a time.

使用 dbx 程序启动调试会话的最为常见的 3 种方法是： 对指定的对象文件运行 dbx 命令; 使用 -r 标志在异常结束的程序上运行 dbx 命令; 使用 -a 标志在已在进行中的进程上运行 dbx 命令; 启动 dbx 命令时，它检查用户当前目录和用户 $HOME 目录中的 .dbxinit 文件。

如果 dbx 已在运行，还可以使用 debug 命令将 dbx 连接到运行中的进程： 要将 dbx 连接到包含 Java 代码和 C JNI（Java Native Interface，Java 本地接口）代码或 C++ JNI 代码的运行中的进程： 有关 debug 命令的更多信息，请参见 debug 命令。 要在 dbx 中运行最近装入的程序，请使用 run 命令。 如果最初键入 run 命令时没有使用参数，则程序便在没有参数的情况下运行。 要传递参数或重定向程序的输入或输出，请使用下列语法： 例如： 运行包含 Java 代码的应用程序 …

Starting the debugger: Give the 'dbx' command along with the name of the exe-cutable you wish to examine. For example: % dbx a.out executes a.out in debigging mode. After this command your process is run in the debug mode (i.e., by dbx) with the prompt (dbx)

Syntax dbx [ -a ProcessID ] [ -c CommandFile ] [ -d NestingDepth ] [ -I Directory ] [ -k ] [ -u ] [ -f ] [ -r ] [ -x ] [ ObjectFile [ CoreFile ] ] Description The dbx command provides a symbolic debug program for C, C++, Pascal, and FORTRAN programs, allowing you to carry out operations such as the following: * Examine object and core files.

dbx is an interactive, source-level, command-line debugging tool. You can use it to run a program in a controlled manner and to inspect the state of a stopped program. dbx gives you complete control of the dynamic execution of a program, including collecting performance and memory usage data, monitoring memory access, and detecting memory leaks.
