shell - How to merge multiple files into single file in given directories -

i want write shell script merge contents of multiple files in given directories.

dir1 contains sample1.txt sample2.txt     sample1.txt contents  :---this sample1 file     sample2.txt contents  :---this sample2 file  dir2 contains demo1.txt demo2.txt     demo1.txt contents  :---this demo1 file 

i tried :

(find /home/dir1  /home/dir2 -type f | xargs -i cat {} ) > /result/final.txt 

it worked!

this sample2 file  sample1 file  demo1 file 

however output appears in single line need every file's output in separate new line. this:

this sample1 file sample2 file   demo1 file 

how achieve this?

any appreciated in advance.

your files don't end newlines, , therefor there no newlines in output file.

you should either make sure input files end newlines, or add them in find command:

find /home/dir1  /home/dir2 -type f -exec cat {} \; -exec echo \;
