Sorry for the confusion. Here are the input files and required output
This is the input file where it contains unique sequences. i have more than million such unique sequences.
Query:
These are multiple files. for example i am showing with 3 files. i have more than 20 such files. each file contains more than 10 million sequences each
File1:
File2:
File3:
I need the following output. Search has to be exact for the count.

Please advice how can we search for a string say (abc) in multiple files and to get total occurrence of that searched string. (Need number of records that exits in period of time).
File look like this (read as filename.yyyymmdd)

Hey,
I've been trying to break a massive fasta formatted file into files containing each gene separately. Could anyone help me? I've tried to use the following code but i've recieved errors every time:
for i in *.rtf.out
do
awk '/^>/{f=++d".fasta"} {print > $i.out}' $i

Hi,
I want to search only duplicate sequence number in file e.g

kalign
KALIGN(1) Kalign User Manual KALIGN(1)NAME
kalign - performs multiple alignment of biological sequences.
SYNOPSIS
kalign [infile.fasta] [outfile.fasta] [Options]
kalign [-i infile.fasta] [-o outfile.fasta] [Options]
kalign [< infile.fasta] [> outfile.fasta] [Options]
DESCRIPTION
Kalign is a command line tool to perform multiple alignment of biological sequences. It employs the Muth?Manber string-matching algorithm,
to improve both the accuracy and speed of the alignment. It uses global, progressive alignment approach, enriched by employing an
approximate string-matching algorithm to calculate sequence distances and by incorporating local matches into the otherwise global
alignment.
OPTIONS -s -gpo -gapopen -gap_open x
Gap open penalty .
-e -gpe -gap_ext -gapextension x
Gap extension penalty.
-t -tgpe -terminal_gap_extension_penalty x
Terminal gap penalties.
-m -bonus -matrix_bonus x
A constant added to the substitution matrix.
-c -sort <input, tree, gaps.>
The order in which the sequences appear in the output alignment.
-g -feature
Selects feature mode and specifies which features are to be used: e.g. all, maxplp, STRUCT, PFAM-A?
-same_feature_score
Score for aligning same features.
-diff_feature_score
Penalty for aligning different features.
-d -distance <wu, pair>
Distance method
-b -tree -guide-tree <nj, upgma>
Guide tree method.
-z -zcutoff
Parameter used in the wu-manber based distance calculation.
-i -in -input
Name of the input file.
-o -out -output
Name of the output file.
-a -gap_inc
Increases gap penalties depending on the number of existing gaps.
-f -format <fasta, msf, aln, clu, macsim>
The output format.
-q -quiet
Print nothing to STDERR. Read nothing from STDIN.
