Full Discussion: Consolidating multiple outputs in one file

OK, then you have 3 programs running that create output.
Would seem that you would want to create one watcher program, perhaps run at regular interval via a cron job.
The watcher program would look to see if the three output files have been created. It would then combine the three files into one.

Some things to consider - is this daily?
Because then you may want to also check to see if you have already created the combined file; thus perhaps checking for the "NOT" existence of the daily combined file.

Another consideration - the order or organization of the combined file. Should the files be combined in the order completed or another order.

dh_lisp

DH_LISP(1)						User Contributed Perl Documentation						DH_LISP(1)

NAME

       dh_lisp - register Common Lisp source and implementations

SYNOPSIS

       dh_lisp [debhelper options] [implementation]

DESCRIPTION

       dh_lisp is a debhelper program that is responsible for registering Common Lisp source and implementations with the Common Lisp Controller.

       For Common Lisp library packages dh_lisp will automatically generate the postinst and prerm commands needed to interface with the Common
       Lisp Controller. It also links the given ASDF system definitions appropriately. It takes into account all ASDs that you installed below
       usr/share/common-lisp/source (for example with dh_install(1)).

       If dh_lisp finds precompiled files from CLISP, SBCL or CMUCL, it will add a dependency on the implementation that can read the FASL version
       used by the implementation currently installed. (this is most likely the one which built the binaries in the package)

       If you supply implementation, dh_lisp automatically installs the implementation-specific script, which is expected to reside in
       debian/implementation.sh. dh_lisp automatically generates the necessary maintainer scripts to register the implementation with the Common
       Lisp Controller.

OPTIONS

       -n, --noscripts
	   do not add to maintainer scripts

       -d  do not generate dependencies on implementations for binary files in the package

       implementation
	   Install the debian/implementation.sh script and generate maintainer scripts to (un)register implementation at the Common Lisp
	   Controller.

NOTES

       Note that this command is not idempotent. "dh_clean -k" should be called between invocations of this command. Otherwise, it may cause
       multiple instances of the same text to be added to maintainer scripts.
