Copy or Move problem

Copy or Move problem
Hi All,
I have a simple shell script to move .txt file(s) from a source directory one after another to the destination. The source directory is shared to windows using samba. The source files are arriving continuously and approx size is 10-15 KB. Some time the file size reached upto 100 KB and than the problem starts. The moving script is moving an incomplete file. Actually the file moving program is a continuous daemon which starts moving file immediately it appeared in the source. I have tried a sleep 2 before moving, but it's also failed in case the file is some more bigger than 100 KB.
Now I wanted to know is there any mechanism available to check if the source file is not in use by any other process? It means, I need to move or copy the file only when its being released by its producer process. It might be easier in Unix using ps command, but I don't know how to check it on a samba shared folder.
Can any body among you please give me a hand please?
Regards.

git-mv
GIT-MV(1) Git Manual GIT-MV(1) NAME
git-mv - Move or rename a file, a directory, or a symlink SYNOPSIS
git mv <options>... <args>... DESCRIPTION
This script is used to move or rename a file, directory or symlink. git mv [-f] [-n] <source> <destination> git mv [-f] [-n] [-k] <source> ... <destination directory> In the first form, it renames <source>, which must exist and be either a file, symlink or directory, to <destination>. In the second form, the last argument has to be an existing directory; the given sources will be moved into this directory. The index is updated after successful completion, but the change must still be committed. OPTIONS
-f, --force Force renaming or moving of a file even if the target exists -k Skip move or rename actions which would lead to an error condition. An error happens when a source is neither existing nor controlled by GIT, or when it would overwrite an existing file unless -f is given. -n, --dry-run Do nothing; only show what would happen AUTHOR
