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. In addition to simply viewing operation of the program, variables can be manipulated and a wide range of expressions can be evaluated and displayed.

History
dbx was originally developed at University of California, Berkeley, by Mark Linton during the years 1981–1984[1] and subsequently made its way to various vendors who had licensed BSD.
Availability
dbx is provided with AIX,[2] and was also provided with IRIX[3] and Tru64 UNIX.[4]
It is included as part of the Oracle Solaris Studio product from Oracle Corporation,[5] and is supported on both Solaris and Linux. It supports programs compiled with the Oracle Solaris Studio compilers and GCC.
It is also available on IBM z/OS systems, in the UNIX System Services component.[6] dbx for z/OS can debug programs written in C and C++, and can also perform machine level debugging. As of z/OS V1R5, dbx is able to debug programs using the DWARF debug format. z/OS V1R6 added support for debugging 64-bit programs.
GCC removed support for stabs debugging symbols in release 13, so that dbx is not supported as a debugger for GCC-compiled code.[7]
