Hi.

Using grep, assuming that the 24 files will fit into memory available:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate inverse, "-v", match, grep with auxiliary file.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C grep

pl " Input data file primary data*:"
head primary data*

pl " Results:"
grep -v -f <( cat data* ) primary

exit 0

producing:
Code:
$ ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny, workstation) 
bash GNU bash 3.2.39
grep GNU grep 2.5.3

-----
 Input data file primary data*:
==> primary <==
123abc
456def
789ghi

==> data1 <==
123abc
456def
891jkl

==> data2 <==
234mno
123abc
456def

-----
 Results:
789ghi

See man pages for details.

Best wishes ... cheers, drl

vcf-compare

VCF-COMPARE(1)							   User Commands						    VCF-COMPARE(1)

NAME

       vcf-compare - compare bgzipped and tabix indexed VCF files

SYNOPSIS

       compare-vcf [OPTIONS] file1.vcf file2.vcf ...

DESCRIPTION

       About: Compare bgzipped and tabix indexed VCF files. (E.g. bgzip file.vcf; tabix -p vcf file.vcf.gz)

OPTIONS

       -c, --chromosomes <list|file>
	      Same as -r, left for backward compatibility. Please do not use as it will be dropped in the future.

       -d, --debug
	      Debugging information. Giving the option multiple times increases verbosity

       -H, --cmp-haplotypes
	      Compare haplotypes, not only positions

       -m, --name-mapping <list|file>
	      Use  with -H when comparing files with differing column names. The argument to this options is a comma-separated list or one mapping
	      per line in a file. The names are colon separated and must appear in the same order as the files on the command line.

       -R, --refseq <file>
	      Compare the actual sequence, not just positions. Use with -w to compare indels.

       -r, --regions <list|file>
	      Process the given regions (comma-separated list or one region per line in a file).

       -s, --samples <list>
	      Process only the listed samples. Excluding unwanted samples may increase performance considerably.

       -w, --win <int>
	      In repetitive sequences, the same indel can be called at different positions. Consider records this far apart as matching (be  it  a
	      SNP or an indel).

       -h, -?, --help
	      This help message.
