[Crash-utility] documentation of crash flags [was: crash-4.0-4.3 and linux-2.6.22.1-20.fc7]
| From: Steve Dickson <SteveD(a)redhat.com>
| I've tried both crash and crash -f with no luck.
How did you find out about -f flag? I don't see it in crash(8) nor in
the output of crash --help.
Flags known to crash, extracted from main.c:
--memory_module
--memory_device
--no_kallsyms
--no_modules
--no_namelist_gzip
--help
--data_debug
--no_data_debug
--no_crashrc
--no_kmem_cache
--kmem_cache_delay
--readnow
--smp
--machdep
--version
--buildinfo
--shadow_page_tables
--cpus
--no_ikconfig
--hyper
--p2m_mfn
--zero_excluded
--no_panic
-f
-g
-H
-h
-e
-t
-i
-v
-s
-L
-S
-c
-d
-p
-m
Flags listed in crash(8) and output of crash --help:
-h
-v
-s
-i
-d
-S
It would be good if more of the flags were documented.
Also: getopt makes it easy to add a long option name as a synonym for
a one-character option. I think that you can use this feature to help
make options clearer. For example, --force could be added as a
synonym for -f at the cost of one more line initializing long_options.
