Shell Programming and Scripting

I have many log files in various subdirectories of a parent directory.

The directory structure e something like this:

Parent directory:

/home/linus/logfiles/

This parent directory has many subdirectories, like this:

.../logfiles/jack
.../logfiles/helen
.../logfiles/sue
.../loffiles/jack
etc...

New subdirectories are being constantly, and automatically, created. Of course new logs files are also being constantly, and automatically, created.

All log files are ascii files and have the .txt extension.

Well, what I need is a bash script which creates, on every and each subdirectory, a new ascii file with the contents of all log files existing on that specific subdirectory.
So I want the bash script to create a new concatenated file on every and each subdirectory.

Every concatenated file must be created with the contents of all ascii file located at the specific subdirectory.
After each of these concatenated files is created, all log files should be deleted.

It would be good if each concatenated file would be created with the name of the subdirectory on it resides plus the extension .txt. So, for instance, on a subdirectory named "james", the concatenated file should be created with the name "james.txt".

I would be very grateful if someone could post a bash script which solves this problem.

Thank you for your kind help, cfajohnson !
You are great.
It works like a charm!

@cfajohnson:

What is "${PWD##*/}" ?

POSIX parameter expansion.

It removes the longest matching pattern (*/) from the beginning of the value of the variable.

In practice, it removes the directory portion of a filepath, leaving only the filename.

Off topic. Welcome back cfajohnson. Happy New Year.

Thanks a lot cfajohnson. I do not know much about shell scripting. I tried to run your code to concatenate all the files in the subdirectories. But that didn't work. Will appreciate if you please send me the script to concatenate all the files in several subdirectories in linux. Thanks once again!
