My input looks like this

Files
Code:
20140902114511523AAA112.txt
20140902114511523BBB113.txt
20140902114511523XXX114.txt

Within each file there values look like this.
Code:
01650126861409662618TUCAAAA_____#20140902075659
01650018671409678351TUCABBB_____#20140902121932
01650070281409691297TUCARSA_____#20140902155457
01650133911409663109TUCAPDS_____#20140902155457

Initially was i just going to cat the files and grep the out put and count

eg. cat *.txt|grep TUCAAAA|wc -l for each folder and year.

I know there must be a much simpler way then pasting in hundreds of count lines into a .sh script and running that.

Another thought i had was to get a unique values, then do something like this.

Code:
while read line ; do
        a=`cat /home/test/2014/01/*.txt|grep $line|wc -l`
        echo $line $a >> /home/test/counts.txt
done < /home/test/values.txt

It's getting the unique values in the first place that is holding me up.

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
