HP-UX 11i Version 1.5 Release Notes, May 2001

Programming
ADB Debugger Tool
Chapter 7132
If you wish, you can specify the old adb behavior on Itanium-based
systems by giving the -o command line option to adb. Another way to
enable old behavior is to add the following line to the file $HOME/.adbrc.
$a backcompat 1
Changes in ADB Command Line Syntax
The -k and -m command line options are no longer required. If you wish
to look at a crash dump, you simply specify the crash dump directory as
the sole argument. (In previous versions of adb, the -k option was
required to recognize HP-UX crash dumps or /dev/mem. The -m option
was required to recognize multiple file HP-UX crash dumps.) In the
backward compatibility mode of operation of adb, the -k and -m options
are ignored with a warning.
ADB Command Prefix Changes
New adb commands no longer require a $ prefix (as they did in previous
versions of adb). The following examples show the old syntax and the
equivalent new syntax.
Example 7-1 To quit adb
Old command: $q
New command: q
Example 7-2 To print the value of a variable named q in hexadecimal:
Old command: q/X
New command: p q/x
ADB Command Processing
The new version of adb ignores the SIGQUIT signal. However, on SIGINT
signal adb interrupts the current command and waits for the next
command. An interrupted command will not update any state variables.
In this case, adb prints a warning message.
adb exits on an EOF. EOL is treated as a command with no command
components and interpreted accordingly.
