If you need to copy one folder to multiples targets using him relative name, you can use xargs for echo command:
[bash]echo target_*/[/bash]
This will return all your target folders:
[bash]target_a target_b target_n[/bash]
Now, combine the xargs output as parameter for /bin/cp command, specifying the source of copy:
[bash]echo target_* | xargs -n 1 /bin/cp source/* -Rfv[/bash]
Now, all your targets will have the same files.
