dbx

Options
this phase of the dbx startup process. Any subcommands in the .dbxinit file are
executed just before the dbx prompt is displayed.
You can use the man command to view descriptions of dbx subcommands. To do
this, you must prefix all subcommands with dbx. For example, to view a description
of the dbx alias subcommand, you would enter the following:
man dbxalias
–a ProcessID
Attaches the debug program to a running process. The debug program
becomes active as soon as the process wakes up. To attach the debug
program, you need authority to use the kill command on this process.
–A ProcessID
Reattaches the debug program to a running process that is already being
debugged by dbx. Use this option to reattach a child process that was
created when a debugged parent process did a fork while multiprocess
debugging mode was active. To reattach to the debug program, you need
authority to use the kill command on this process.
-b Suppresses processing of .dbxsetup and .dbxinit files (bare startup).
–c script
Runs dbx subcommands from a specified script file before reading from
standard input.
–C dump–filename
Puts dbx in dump reading (core file) processing mode.
–d Deprecated. This option will be ignored and remains only for compatibility
purposes.
–f Deprecated. This option will be ignored and remains only for compatibility
purposes.
–F Starts debug target in a different address space than the one dbx currently
resides in; or starts dbx in its own address space when attaching to a
running target program.
–h Prints the dbx command syntax.
–I directory
Appends the given directory to the list of directories searched for source
and debug files. The default list contains the working directory and the
directory containing the object files. The search path can also be set with
the use subcommand.
–m dbxmode
Instructs dbx to start in a specific mode:
v Specifying –m4 forces dbx to run in 31-bit mode, even on a machine
capable of running it in 64-bit mode.
v Specifying –m8 forces dbx to run in 64-bit mode. If this is impossible,
dbx will terminate.
-p ipaddress | name[:port]
Tells dbx to open a socket and connect to the ipAddress:port or
machineName:port which is assumed to be a GUI that supports remote
