git pre-commit error : Check filenames : .git/hooks/pre-commit; line 25; syntax error : unexpected end of file

Question

Below is hook code I am using for pre-commit in VS 2019. I want to restrict some files being committed always. Trying with string.exe. But getting error. Help needed on this.

#!/bin/sh
#!/usr/bin/env bash
listchange=$(git diff --name-only) 

echo "Check filenames:"

wrongfilenames=$(
            for filename in $listchange 
            do
                fname= $filename
                if [[ $fname = 'strings.exe' ]]; then 
                    echo $fname;
                    echo "has strings.exe"
                fi
            done
        );
        
if [ -n "$wrongfilenames" ] ; then
echo "The following files need not to commit:"
echo "$wrongfilenames"
echo "Commit rejected, fix it and try again."
exit 1
else
echo "....OK"

It looks like you are missing a fi at the end of the conditional check.

#!/bin/bash
listchange=$(git diff --name-only) 

echo "Check filenames:"

wrongfilenames=$(
    for filename in $listchange 
    do
        if [[ "$filename" = "strings.exe" ]]; then 
            echo "$filename"
            echo "has strings.exe"
            # TODO: take the appropriate action(s) here
            return 1 # => quit with error
        fi
    done
);
        
if [ -n "$wrongfilenames" ] ; then
    echo "The following files need not to commit:"
    echo "$wrongfilenames"
    echo "Commit rejected, fix it and try again."
    exit 1
else
    echo "....OK"
fi

NOTE: it is a good practice to add double quotes around $var when checking content against string. Indeed, if the $var has white-spaces it will not work as expected.
