Copy content of a file into multiple files
 
Hello everyone,
I am trying to copy the content of a text file into multiple files in a single command. Is there any way to achieve this?
For example, A.txt contains:
This is a simple text file.

And I want to copy this content into some other files, named B.txt, C.txt ... so on.

Thansk for your help!

Simplest solution is to do it with a loop.

The cp command doesn't support multiple destinations.

Code:
cat A.txt | tee B.txt C.txt D.txt >/dev/null

Alright, we can achive this using following simple script:

#!/bin/sh
for i in `cat fileslist.txt`
do
more [file] > $i
done

For users information, [file] is the file whose conetent you want to copy in all other files. And secondly, put a list of all files, in which you want to copy ccontent of the [file] file, into fileslist.txt file.

I hadn't used tee command for a long time, so perhaps it skipped from my mind. Thanks, you make me remember that!

You shouldn't be running "for i in `cat fileslist.txt`", as the for loop will split on any spaces in those filenames. Using a "while read" would avoid this problem.

or another way:

Code:
for i in {B,C,D}; do cp A.txt "$i".txt; done
