Hi

If the directory structure depth is 1, then simple :

Code:

cat * */*

But the nicer solution is with [tt]find[/tt] ( if your [tt]find[/tt] has -exec option ) :

Code:

find . -exec cat '{}' \;

Hi

Uff. Better do not [tt]cat[/tt] anything, limit to files only :

Code:

find . -type f -exec cat '{}' \;

I'm not near a unix box, but what about using find:

Code:

find /path/to/files -type f -print|while read myfile
do
   cat $myfile >> Main.txt
done

Hi

Or if your [tt]find[/tt] has no -exec option, then through [tt]xargs[/tt] :

Code:

find . -type f | xargs cat

And Mike, you get only the last file in main.txt ...

for i in *
do
test -f $i && cat $i
done > main.txt

How?

Won't you have to create an empty 'main.txt' anyway?

Sorry, I don't see the problem.
My point is to not enter the loop with a not globbed *

Hope This Helps, PH.

for i in `ls |grep -v main.txt`;do
cat $i >> main.txt
done

would * not include . & ..

and as far as UUoLS - IDGAF it works
