Alicia

How do I stop my runaway LDAS?

You can use INT interrupt(CTRL-C) to stop your LDAS.

Initial command at starting

To execute some command at staring, modify /usr/bin/alicia written in perl.
The following is an example:

$alicia = new Alicia('crash');
$alicia->init();
print $alicia->pass_through('sys');
$alicia->run();

If you installed Alicia under default configuration, alicia is at /usr/bin/alicia on your system.

Change the prompt name

If you don't like the prompt name 'alicia', modify the program name /usr/bin/alicia to /usr/bin/your favorite name

How to find out what processes are using the most memory.

For example, using the external program..

alicia> ps | sort +7n;

Using LDAS..

sub psmem {
    my ($text, @pss, $header, @mps);
    $text = pass_through('ps');
    $text =~ s/>/ /g;
    @pss = split(/\n/, $text);
    $header = shift @pss;
    @mps = sort { (split(/\s+/,$a))[8]<=>(split(/\s+/,$b))[8]; } @pss;
    unshift (@mps, $header);
    return join("\n", @mps);
}
1;

Alter perl-like fashion of Alicia shell to bash-like fashion

Modify the ShellStyle tag in your config file from perl to bash

To wrap the other dump editing tool (e.g. Lcrash)

First of all, please refer to CRASH.pm in the directory where Alicia was installed. For example, to wrap 'lcrash', some functions CRASH.pm has must be implemented.

These functions are:

• init()
  The init routine handles the messages from lcrash until lcrash displays the lcrash's prompt (>>) and sets the environment of lcrash.
• command()
  Returns the list of lcrash commands
• search('entered command')
  Determine whether the entered command is lcrash's command or help.
• wipeout()
  Wipes out the output message from lcrash.
• pass_through('lcrash command')
  Pass to lcrash as it is and Return the result as it is.
• kernel(address, struct name, member, type)
  Returns the value of structure member.
• get_mem(symbol,[words))
  Returns the data from symbol's address.
• get_val(symbol)
  Returns the value of symbol.
• get_addr(symbol)
  Returns the address of symbol.
• get_increments
  Returns the word alignment.
