NAME
set - set a process context or internal crash variable
SYNOPSIS
set [pid | taskp | [-c cpu] | -p] | [crash_variable [setting]] | -v
DESCRIPTION
This command either sets a new context, or gets the current context for
display. The context can be set by the use of:
pid a process PID.
taskp a hexadecimal task_struct pointer.
-c cpu sets the context to the active task on a cpu (dumpfiles only).
-p sets the context to the panic task, or back to the crash task on
a live system.
-v display the current state of internal crash variables.
If no argument is entered, the current context is displayed. The context
consists of the PID, the task pointer, the CPU, and task state.
This command may also be used to set internal crash variables. If no value
argument is entered, the current value of the crash variable is shown. These
are the crash variables, acceptable arguments, and purpose:
scroll on | off controls output scrolling.
radix 10 | 16 sets output radix to 10 or 16.
refresh on | off controls internal task list refresh.
print_max number set maximum number of array elements to print.
console device-name sets debug console device.
debug number sets crash debug level.
core on | off if on, drops core when the next error message
is displayed.
hash on | off controls internal list verification.
silent on | off turns off initialization messages; turns off
crash prompt during input file execution.
(scrolling is turned off if silent is on)
edit vi | emacs set line editing mode (from .crashrc file only).
namelist filename name of kernel (from .crashrc file only).
dumpfile filename name of core dumpfile (from .crashrc file only).
Internal variables may be set in four manners:
1. entering the set command in $HOME/.crashrc.
2. entering the set command in .crashrc in the current directory.
3. executing an input file containing the set command.
4. during runtime with this command.
During initialization, $HOME/.crashrc is read first, followed by the
.crashrc file in the current directory. Set commands in the .crashrc file
in the current directory override those in $HOME/.crashrc. Set commands
entered with this command or by runtime input file override those
defined in either .crashrc file. Multiple set command arguments or argument
pairs may be entered in one command line.
EXAMPLES
Set the current context to task c2fe8000:
crash> set c2fe8000
PID: 15917
COMMAND: "bash"
TASK: c2fe8000
CPU: 0
STATE: TASK_INTERRUPTIBLE
Set the context back to the panicking task:
crash> set -p
PID: 698
COMMAND: "gen12"
TASK: f9d78000
CPU: 2
STATE: TASK_RUNNING (PANIC)
Turn off output scrolling:
crash> set scroll off
scroll: off
Show the current state of crash internal variables:
crash> set -v
scroll: on
radix: 10 (decimal)
refresh: on
print_max: 256
console: /dev/pts/2
debug: 0
core: off
hash: on
silent: off
edit: vi
namelist: vmlinux
dumpfile: vmcore
Show the current context:
crash> set
PID: 1525
COMMAND: "bash"
TASK: c1ede000
CPU: 0
STATE: TASK_INTERRUPTIBLE
