copy a file to a destination with different names

Question

I want to copy a text file to a directory with multiple names with curly braces:

cp /path/to/file/a.txt /path/to/file/{b,c,d}.txt

But it gives me the error: target '/path/to/directory/d.txt' is not a directory

Solution

for i in {b,c,d}; do cp /path/to/directory/a.txt /path/to/file/$i.txt; done

i'm really new to this. it didn't work, no error occurred, but there is no files inside the directory. should it be inside a script?
