I have five VCF files, for five different species. They were all aligned to the same reference sequence. Some VCF files are longer than others, as more sequence aligned to the reference sequence in different species. The different chromosomes also have different numbers of variants for each species.
These are short segments of two VCFs to explain my point:
ACmerged_contig_7648 573 . A . 52 . DP=1;MQ0F=0;AN=2;DP4=0,1,0,0;MQ=22 GT 0/0
*ACmerged_contig_7648 574 . T . 52 . DP=1;MQ0F=0;AN=2;DP4=0,1,0,0;MQ=22 GT 0/0
ACmerged_contig_9049 831 . T . 58 . DP=1;MQ0F=0;AN=2;DP4=1,0,0,0;MQ=28 GT 0/0*
ACmerged_contig_9049 832 . A . 58 . DP=1;MQ0F=0;AN=2;DP4=1,0,0,0;MQ=28 GT 0/0

ACmerged_contig_9049 259 . T . 52 . DP=1;MQ0F=0;AN=2;DP4=1,0,0,0;MQ=22 GT 0/0
As you can see, the lines in italics show that alignments to the chromosomes stop and start at different sites for the different species. Is there a software that will remove sites of VCFs that are not present in all of my VCF files? i.e. a way to trim my VCF files to only posess the sites found in all the VCF files?
