awk 'BEGIN{RS=">";FS="\n"} {A[$1]=$2} END{for (i in A) {if (i) print ">"i,FS,A[i]}}' file1.fasta file2.fasta

This only works for 2-line fasta sequence files (i.e. each entry has two lines, One starts with ">" as the header, the other is the DNA sequence. @vgersh99, could you please elaborate your code for scenario 2)? Thanks!
My previously posted attempt was for the provided sample files ONLY - 2 lines for each sequence: 1 header and 1 "data" lines.
Had the OP elaborated on the possible other sample data files, an alternate solution would have been provided.

NAME
search2tribe - Turn SearchIO parseable reports(s) into TRIBE matrix SYNOPSIS
Usage: search2tribe [-o outputfile] [-f reportformat] [-w/--weight] file1 file2 .. DESCRIPTION
This script is probably too slow for most people's uses. It is better to use something like scripts/searchio/fastam9_to_table, -m 9 output from BLAST, or the blast2table from the BLAST O'Reilly book to get a tabular output from these programs and then feed the table into MCL with the mcxdeblast script and the --m9 option. This script will turn a protein Search report (BLASTP, FASTP, SSEARCH) into a Markov Matrix for TribeMCL clustering. The options are: -o filename - the output filename [default STDOUT] -f format - search result format (blast, fasta) (ssearch is fasta format). default is blast. -w or --weight VALUE - Change the default weight for E(0.0) hits to VALUE (default=200 (i.e. 1e-200) ) -h - this help menu Additionally specify the filenames you want to process on the command-line. If no files are specified then STDIN input is assumed. You specify this by doing: search2tribe < file1 file2 file3 AUTHOR
