FILLUP(8)FILLUP(8)NAMEfillup - the SuSE tool for merging config files
SYNOPSISfillup [options] basefile addfile outputfile
fillup [options] basefile addfile
fillup -V|--version ...
fillup -h|--help ...
DESCRIPTIONfillup - merges input files into one resulting output file. Usually,
each file is a configuration file.
fillup merges files which are holding variables (ie configuration or
environment variables). A variable is defined by an entity composed of
a preceding comment, a variable name, an assignment delimiter, and a
related variable value. A variable is determined by its variable name.
A preceding comment is optional. An assignment delimiter may be
optional, but if there is an assignment delimiter, a variable name must
precede it. The last entity may be composed only of a comment.
Only if variables are included in both input files (basefile and
addfile) fillup has to select one of the variables. Otherwise, if
variables are included only in one of the input files they are added to
the resulting output file (with the exception of the -i|--ignoreDefi‐
nites option).
The functionality is now controlled by a parameter which determines
whether a variable included both in the basefile and in the addfile is
taken from the former or from the latter. Furthermore, a parameter
controls whether the variable is removed from a copy of the basefile.
To keep the fillup v1.04 functionality, the outputfile parameter can be
omitted -- this means the resulting output file is named exactly like
the first input file name (basefile = outputfile).
If variables should be removed from the basefile, the basefile is not
touched, but the result is written to basefile.new.
If basefile includes a header as part of the first variable this header
is preserved only for the outputfile if after the header an empty line
follows.
Starting with version 1.20 handling of metadata for /etc/sysconfig
files is included. Metadata is part of preceding comment, each meta‐
data line begins with double hash ("##"). A metadata line contains a
pair <keyword>:<value>. The value itself can be described on several
lines, each beginning with double hash and the optional keyword.
EXAMPLESfillup-m "/etc/rc.config" "my.config" "/etc/rc.config"
All variables of "/etc/rc.config" are passed to the resulting output
file "/etc/rc.config". Variables defined only within "my.config" are
appended.
fillup-exchange "/etc/rc.config" "my.config"
Only variables of "/etc/rc.config" that are not also defined within
"my.config" are passed to the resulting output file "/etc/rc.config".
All variables of "my.config" are appended.
fillup-m -r "/etc/rc.config" "my.config" "/etc/rc.config"
All variables of "/etc/rc.config" are passed to the resulting output
file "/etc/rc.config". Variables defined only within "my.config" are
appended. The additional parameter '-r' removes variables defined more
than once from a copy of "/etc/rc.config". "/etc/rc.config" isn't
touched and the result of the removal is written to "/etc/rc.con‐
fig.new".
fillup-i "/etc/rc.config" "my.config"
This is a filter functionality. Variables of "/etc/rc.config" are only
passed to the resulting output file "/etc/rc.config" if they are
defined in both input files. Because "my.config" is normally only a
list of variable names from "/etc/rc.config", this is named filter
functionality. Additionally variables of "my.config" are appended if
they are defined only in "my.config".
OPTIONS
There are many options, which are displayed if fillup is called without
or with the -h or --help option.
Most of the parameters are based on v1.04. In the sequel only useful
parameters are listed:
-i, --ignoreDefinites filter functionality
-t, --trailing save trailing comment
-v, --verbose maximum output to screen
-V, --version print fillup version and exit
-c | --char <char> use <char> as comment marker
-d | --delim <char> use <char> as delimiter
-m, --maintain maintaining the basefile
-x, --exchange exchanging the basefile
-r, --remove removing within a copy
EXIT CODEfillup returns EXIT_SUCCESS on successful completion. Otherwise, an
exception handler is called, which may return EXIT_FAILURE;
BUGS
If a bug occurs which is not based on invalid options or missing input
files, please add the option -v|--verbose to the call. The result and
some classifications are displayed to locate the bug.
With handlung of metadata and thus replacement of information within
files a hardly documented debugging feature is introduced by adding two
options on command line: information about a special variable (given by
--variable <variable name>) is logged into a special file (determined
by --logfile <file name>).
