Copy files to a destination folder only if the files already exist. but the source files have a different file extension

Copy files to a destination folder only if the files already exist. but the source files have a different file extension.

i.e I have a backup of some files with ".desktop.in" extension and I want to copy to destination where the files extensions are ".desktop" and only the files that already exist in the destination.

source folder contain:

• a.desktop.in


• b.desktop.in


• c.desktop.in

destination folder contain:

• a.desktop


• b.desktop

Want only to overwrite a.desktop and b.desktop files

Tried this:

for file in /destination/*.desktop;do cp /src/"${file##*/}".in "$file";done

But that doesn't look optimized for that task.

Do you know a better way to do that?
