How to Find a String in Each File in a Directory

Hi,

I have the ff. list of files in the dir named /home/joule/unix/archive:
Code:
$ /home/joule/unix/archive
joule1.gz
joule2.gz
joule3.gz
joule4.gz
joule5.gz
joule6.gz
joule7.gz
joule8.gz

What I would like to do is to find this string in a group of files in the directory above:

String to find:
Code:
20101108

Since I have more than a thousand files to search into, is there any easier way to do this?
# 2  
Code:
for file in /home/joule/unix/archive/*.gz; do
  zcat "$file" | grep 20101108
done

or

Code:
for file in /home/joule/unix/archive/*.gz; do
  zcat "$file" | grep $(date "+%Y%m%d")
done

Many programming languages do not allow you to begin a variable name with a number as it would make it more difficult for a compiler or interpreter to parse a program's source code.
