amgetconf
AMGETCONF(8) System Manager's Manual AMGETCONF(8)
NAME
amgetconf - look up amanda.conf variables
SYNOPSIS
amgetconf [ config ] parameter
DESCRIPTION
Amgetconf looks up parameters in amanda.conf, the Amanda configuration file, or from the build and runtime environment, and returns their
corresponding value.
If config is not specified, amgetconf assumes it is being run from the configuration directory and that amanda.conf is present.
If parameter begins with build., the (case insensitive) string following the period is a build environment variable. Variables without a
value (e.g. XFSDUMP on a system that does not support that type of file system) will not report an error and will return an empty string as
the value. Flag variables (e.g. USE_AMANDAHOSTS) will return 1 if the flag is set or an empty string if it is not.
If parameter begins with dbopen., the string following the period is a program name and an Amanda debug file will be created for the call-
er. The name of the file is returned.
If parameter begins with dbclose., the string following the period is a program name previously used with dbopen., followed by a colon (:)
and the previously opened file name.
See the amanda(8) man page for more details about Amanda.
EXAMPLE
Find out the path to the log file directory:
% amgetconf DailySet1 logdir
/etc/amanda/DailySet1
Find out the current tape type:
% amgetconf DailySet1 tapetype
DLT4000-IV
Find out the default configuration directory:
% amgetconf DailySet1 build.CONFIG_DIR
/etc/amanda
Create, use and close a debug file in a script:
% set debug_file = `amgetconf DailySet1 dbopen.myscript`
% echo debug information >> $debug_file
% amgetconf DailySet1 dbclose.myscript:$debug_file
MESSAGES
amgetconf: no such parameter "param"
Parameter param is not a known keyword (e.g. not a valid amanda.conf keyword). In this case, amgetconf will write "BUGGY" to stdout
as the value.
