/usr/ucb/dbx [options] [objfile [corefile]]

Solaris 2.0 only. A source code debugger for programs written in C, C++, Pascal, and FORTRAN. Programs compiled with the -g option of cc (and other compilers) produce objfile, an object file that includes a symbol table. corefile contains the core image produced when objfile is executed. a.out is the default object file, and core is the default corefile. Dbx commands can be stored in a start-up .dbxinit file that resides in the current directory or in the user's home directory. Dbx executes these commands just before reading the symbol table. See Section 20 for more information on dbx.


-c cmd

Run dbx cmd after initialization.


Collect profile data for debugged program.


Echo input commands on standard output.


Act as if standard input is a terminal.

-I dir

Add dir to the directory search path. The dbx command use resets the search path.


Debug a program that puts the keyboard in up-down translation mode.

-P file_des

Pipe output to the debugger command via file descriptor file_des. debugger passes this option automatically.


Suppress messages during loading (useful during auto-traceback).


Execute objfile right away, then wait for user response from the keyboard.

-s file

Read initialization commands from start-up file.

-sr tmp

Like -s, but then delete start-up file (tmp).

- pid

Debug a currently running program whose process ID is pid (used mainly for auto-traceback).
