Synopsis of options -
-b Brief mode; skip general display of processes
-d Crash dump contains swap image. (default?)
-v Verbose; dump much information about each proc [future]
-t TTY structs to be dumpped
-i Incore inode table to be printed
-c FILE Provide non-standard file name for system image input
-s FILE Provide non-standard symboltable input
-u ADDR Trace a process other than currently selected one
-z Interrupt Trace displayed
aps Print PS & PC at time of interupt (doesn't do anything)
crash examines a dump of unix which it looks for in the file sysdump. It prints out the contents of the gen-
eral registers, the kernel stack and a traceback through the kernel stack. If an aps is specified, the ps and
pc at time of interrupt are also printed out. The dump of the stack commences from a "reasonable" address and
all addresses are relocated to virtual addresses by using the value of kdsa6 found in the dump.
The following options may be specified.
-b Brief mode; skip general display of processes. Only the currently selected process will be traced.
If the -c argument is found, the following argument is taken to be the name of a file containing the
system image. The default is "/usr/sys/core".
If the -s argument is found the following argument is taken to be the name of a file, containing a sym-
bol table which should be used in interpreting text addresses. The default is "/unix".
Force a process to be displayed as if it were active when the crash occurred. addr is the octal
address of the proc table entry.
/unix system namelist
/dev/swap swap device
/usr/sys/core core file
