# e.g. we have 3 files *.txt jules.txt, jules2.txt jules3.txt in the directory "jules":

f00@localhost ~$ cd jules/
f00@localhost jules$ ls
jules2.txt  jules3.txt  jules.pl  jules.txt

# there are different ways of having the jules.pl script having all this files parsed.
# either one can make them all into one, or one can call jules.pl on each of them

# first way is using only FIND to list all files named *.txt and then execute the code "perl jules.pl" for each of these:

f00@localhost jules$ find . -name "*.txt" -exec perl jules.pl {} \;

# works

# we could also make them all into one new file: "all.all" first and have the formated output into the file "result.res":
# warning: i named the files all.all and result.res because all files ending with ".txt" in this directory will be used offcourse

f00@localhost jules$ find . -name "*.txt" | xargs cat >> all.all
f00@localhost jules$ cat all.all
