NAME
crash - analyze kernel dump or active system image SYNOPSIS
crash [ aps ] [ -bdvtiz ] [ -s sfile ] [ -c cfile ] [ -u addr ] DESCRIPTION
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 general 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. -c cfile 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". -s sfile If the -s argument is found the following argument is taken to be the name of a file, containing a symbol table which should be used in interpreting text addresses. The default is "/unix". -u addr 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. FILES
/unix system namelist /dev/swap swap device /usr/sys/core core file SEE ALSO
crash(8), adb(1), ps(1), rstat(1) DIAGNOSTICS
Missing arg Unable to Open file Format Error in symbolfile BUGS
Care should be used in running crash on "/dev/mem". Things can change while crash is running; the picture it gives is only a close approx- imation to reality. AUTHOR
