How to merge multiple files into single file in given directories

Question

I want to write a shell script to merge contents of multiple files in a given directories.

DIR1 contains sample1.txt sample2.txt
    sample1.txt contents  :---this is sample1 file---
    sample2.txt contents  :---this is sample2 file---

DIR2 contains demo1.txt demo2.txt
    demo1.txt contents  :---this is demo1 file---

I tried the solution :

(find /home/DIR1  /home/DIR2 -type f | xargs -i cat {} ) > /result/final.txt

I got the output as well but sequence of file has changed.

this is sample2 file---  this is sample1 file---  this is demo1 file---

I need every file's output ina different line . how to do this? Is there any way to maintain the order of files output like If i want to place particular file's output at the top or so? and what is the use of " xargs -i " option in the cmd?

Thanks.

Answer 1

You can use this:

(find directory -type f | xargs -i cat {} ) > TOTAL

Looks for all files in directory and puts all content in TOTAL.

Answer 2

You need to go directly into that directory:

cat /home/me/mydir/* > /home/me/finalData.txt
