How can I make 5 copies of one file easily?

Question

I can move 5 files to somewhere using:

$ mv my-{1..5}.jpg /path/to/dir/

How can I make copy of one file by 5 times easily

# doesn't work
$ cp my.jpg my-{1..5}.jpg

Is it possible not to use a for loop?

Answer 1

Try this

for f in {1..5}; do cp my.jpg my$f.jpg; done

(don't have bash here to try it myself)

Answer 2

Here is a way to do it without a for loop and without the risks of using eval:

printf '%s\n' {1..5} | xargs -I {} cp my.jpg my-{}.jpg

It's still effectively a loop.

Answer 3

Try tee:

tee <my.jpg >/dev/null my-{1..5}.jpg

Or parallel:

parallel cp my.jpg ::: my-{1..5}.jpg

Answer 4

You can do it without a loop.. using tee and {} brace expansion.

EDIT: (ammended as per Dennis Williamson's comment:

For a file named "my-.jpg"

pre="my-"; suf=".jpg"
<"$pre$suf" tee "$pre"{1..5}"$suf" >/dev/null
