First, you need to define exactly what you mean by "finished copying", and you need to define it precisely.

And remember you're going to have to handle error conditions, too, such as when someone is copying a file remotely and the connection drops before the copy is done.

FWIW, the only person who can tell definitively that any copy is complete is the person sending the file, because the receiver can't know what's being sent as the receiver doesn't have the original. That means if you value reliability and guaranteed correctness, you MUST have the sender somehow flag that the copy is complete. Probably the easiest way is with a rename of the file. Call it something like 'filename.part' while copying, then rename it to 'filename' once the copy is done.

No, you CAN'T reliably use something like lsof on a Linux box to check if any other process has the file open, because that ignores error conditions.

MRENAME(1)						      General Commands Manual							MRENAME(1)

NAME

       mrename - program to rename files

SYNOPSIS

       mrename 'pattern' prefix [option]

DESCRIPTION

       This  manual  page  documents  briefly the mrename command.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       mrename is a tool for easy and automatic renaming of many files.  The 'pattern' is the pattern to search files to rename (quoted  to  avoid
       that  bash  resolve  it),  and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or
       moving files in the new name are explained below.  All parameters are needed, and you have to stay and launch the script in the same direc-
       tory of the files to be renamed. The program should be able to write in this directory.

OPTIONS

       There are only the following three options.

       -c     The option -c will copy each file with the new filename.

       -m     The option -m will move each file in the new filename.

       -h     Display help.

EXAMPLE

       If  you	have  a  directory  with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc..  (that is
       item0prof.jpg, item1forp.jpg etc..) do this:

	  cd /path/to/the/images
	  mrename '*.jpg' item -c

       to copy each matching file into another with the new name

	  mrename '*.jpg' item -m

       to rename each file without keeping a copy with the previous name
