kclog(1M)

NAME

kclog — manage kernel configuration log file

SYNOPSIS

kclog [-a] [-c config] [-f string] [-t type] [-n name] [count]

kclog -C comment

DESCRIPTION

kclog is the administrative command for the HP-UX kernel configuration log file. The log file is automatically maintained by all of the kernel configuration commands (kconfig(1M), kcmodule(1M), and kctune(1M)). Any change to any kernel configuration gets logged to this log file, which is located at /var/adm/kc.log. Note that this file is a plain text file which can be viewed and manipulated using standard Unix file management commands; kclog exists simply for convenience in finding particular log file entries.

Under normal usage, kclog prints the last count entries in the log file. When one of the options is specified, kclog prints the last count entries that match the specified criteria. If count is not specified, it defaults to 1.

Options

-a: kclog will print all entries matching criteria. If this option is not specified, kclog will only print the last count entries that match the specified criteria.
-c config: kclog will print only log file entries describing changes to the saved kernel configuration named config. If this option is not specified, kclog will print log file entries describing changes to any saved or running kernel configuration.
-C comment: kclog will not print any entries. Instead, kclog will create a new entry, as if a kernel configuration change had been made, containing the specified comment. Super-user permissions are required for this option.
-f string: kclog will print only log file entries that contain the given string.
-n name: kclog will print only log file entries that refer to a configuration object (module or tunable) of the given name.
-t type: kclog will print only log file entries that refer to configuration objects of the specified type: module or tunable.

RETURN VALUE

kclog returns zero for success. It returns non-zero and prints a diagnostic message if an error occurs.

EXAMPLES

To see the last three entries in the log:

$ kclog 3

To see the last entry for the tunable file_sys_max:

$ kclog -t tunable -n file_sys_max

To see the last five entries for module changes:

$ kclog -t module 5

To see all entries for module changes:

$ kclog -a -t module 5

To see the last entry mentioning Aberdeen:

$ kclog -f Aberdeen

WARNINGS

The format of the log file may be changed without notice.

Some configuration changes can be made without using the kernel configuration commands. No log file entries are made for such changes.

The log file should not be manually edited. Doing so may cause kclog to behave unpredictably.
