Advanced Debugger
The advanced debugger adb is the standard UNIX debugger found on Solaris 1 and 2, HP-UX and SCO. It is the successor of a debugger called db.Overview
The initial version was written by Stephen R. Bourne. ADB is the standard debugger on Solaris and the Solaris kernel debugger kadb that was introduced with SunOS-3.5 is a minor variant of adb.
A version of ADB was integrated into the BSD kernel as a kernel debugger.
On Solaris, ADB was replaced by the Modular Debugger mdb with Solaris 8 and the ADB command-line interface now is emulated by mdb when it is called as adb. Mdb has become OpenSource with OpenSolaris.
