Git提交前提交钩子添加文件

Question

I am attempting to dump a mysql database and add the .sql dump file to the staging area using a pre-commit hook so it can then be included in the commit (on Windows Server 2012 R2/IIS). The following code dumps the database nicely, but after I commit it still shows the be.sql file in the staging area...sometimes(?) - it seems to be adding the file to staging AFTER committing(?). This is a pre-commit hook so I have no idea why it may be adding the file after the commit takes place:

#!/bin/bash

# Dump Database
/c/Program\ Files\ \(x86\)/MySQL/MySQL\ Server\ 5\.7/bin/mysqldump.exe -u root --skip-extended-insert be > /c/inetpub/wwwroot/directory/be/be.sql

# Add Database
cd /c/inetpub/wwwroot/directory/be
git add be.sql

The behavior is a bit strange - I will see be.sql is still in the staging area so I will make a commit. If I git status afterwards the tree is clean. If I commit again and git status it will display the be.sql file in the staging index as modified (I didn't modify it). And back and forth it goes. I just want it to dump the .sql file, add the .sql file to the staging index, THEN commit so every time the staging index is clean. Any ideas as to why this is happening would be greatly appreciated.

Using:

git commit -m "Message" --allow-empty

when making the commit appears to have worked. It seems as if git needs other staged changes in order for the hook to work. So it was basically not making the commit, but still dumping the be.sql file, which would then show up in the staging index as modified the next time around because the date had changed. In order to allow the commit to fully go through regardless of whether or not there were other staged changes I used the --allow-empty option, which allows a commit with nothing in the staged index.
