Please open a new thread describing your environment and your particular problem giving lots and lots of detail.

How to open a new thread?

@cfajohnson
Please reply to my message. I badly need the solution!

@cfajohnson
I saved your code in test.sh file and then executed from commnad prompt using ./test.sh. But it didn't concatenate files, instead it deleted files from all subdirectories. Please let me know what is wrong. I am concerned

Did you save it exactly as I posted it?

Did you cut and paste or retype it?

If you changed anything, what did you change?

When you ran it, did you get any error messags?

@raj284
It is exceedingly dangerous to take code from the Internet that you think might match your problem and execute it on your computer unless you 100% understand what it is going to do in the context of your computer. If you are ever in this position again please feel free to describe your environment and your problem and post your question and what you are planning to run.

The expert poster cfajohnson has posted code to match the original poster's requirement and received thanks a month ago.
If you have deleted files inadvertantly, ask your Systems Adminstrator to restore them from backup.

Sorry to be blunt but may I recommend that you use your computer to research training courses.

Did you save it exactly as I posted it?
Ans: No

Did you cut and paste or retype it?
Ans: I cut, pasted and edited it as shown below.

If you changed anything, what did you change?
Ans: The only thing I changed is the value of logdir as shown below.

When you ran it, did you get any error messags?
Ans: No.
I saved the script as script.sh in $HOME/testing1 where I have several subdirectories and .txt files into them. I ran script.sh from the command prompt of $HOME/testing1 as ./script.sh

The only messages I got:
cat: file11.txt: input file is output file
cat: file22.txt: input file is output file
......
......
Here is the script I have used:

logdir=$HOME/testing1 ## adjust to taste
for dir in "$logdir"/*/
do
(
cd "$dir"
files=( *.txt )
cat "${files[@]}" > "${PWD##*/}.txt"
rm "${files[@]}"
)
done
