Instead of checking the file size you should check if the file is open. You can use the fuser utility to do that:

Agreed. Copy/rename is the fool proof way to avoid problems.
Hi,
I would like to perform bash which would check the file A.txt to be size 0 or not. If the size is 0, I would copy file B.txt to replace A.txt.
Please help.
Thanks.

cp
cp(1) General Commands Manual cp(1)Name
cp - copy file data
Syntax
cp [ -f ] [ -i ] [ -p ] file1 file2
cp [ -f ] [ -i ] [ -p ] [ -r ] file... directory
cp [ -f ] [ -i ] [ -p ] [ -r ] directory... directory
Description
The command copies file1 onto file2. The mode and owner of file2 are preserved if it already existed; the mode of file1 is used otherwise.
Note that the command will not copy a file onto itself.
In the second form, one or more files are copied into the directory with their original file names.
In the third form, one or more source directories are copied into the destination directory with their original file names.
Options-f Forces existing destination pathnames to be removed before copying, without prompting for confirmation. The -i option is ignored if
the -f option is specified.
-i Prompts user with the name of file whenever the copy will cause an old file to be overwritten. A yes answer will cause to continue.
Any other answer will prevent it from overwriting the file.
-p Preserves (duplicates) in the copies the modification time, access time, file mode, user ID, and group ID as allowed by the permis-
sions of the source files, ignoring the present umask.
-r Copies directories. Entire directory trees, including their subtrees and the individual files they contain, are copied to the speci-
fied destination directory. The directory, its subtrees, and the individual files retain their original names. For example, to copy
the directory including all of its subtrees and files, into the directory enter the following command:
cp -r reports news
