=== How to resolve "Add a new line at the end of this file." ===
Error message: Files should contain an empty newline at the end<ref>[https://gist.github.com/OleksiyRudenko/d51388345ea55767b7672307fe35adf3 Why should text files end with a newline?]</ref>

Solution:
* Add [[Return symbol | new line]] at the end of this file

Another solution:
* Add an new file {{kbd | key=add_newline_to_php_files.sh}} with the following content
<pre>
#!/bin/bash

# Check if a directory path argument has been provided
if [ "$#" -ne 1 ]; then
    echo "Usage: ./add_newline_to_php_files.sh [Directory Path]"
    exit 1
fi

# Retrieve the directory path argument
dir_path="$1"

# Initialize a counter for modified files
modified_count=0

# Iterate through all .php files in the specified directory
for file in "$dir_path"/*.php; do
    # Check if the file exists
    if [ -f "$file" ]; then
        # Read the last line of the file
        last_line=$(tail -n 1 "$file")
        
        # Check if the last line is empty
        if [ "$last_line" != "" ]; then
            # If it's not empty, append a newline character
            echo "" >> "$file"
            # Increment the modified files counter
            ((modified_count++))
        fi
    fi
done

# Display the number of modified files
echo "Number of modified files: $modified_count"



</pre>

* Grant the execution permission {{kbd | key=chmod +x add_newline_to_php_files.sh}}
* Usage {{kbd | key=<nowiki>./add_newline_to_php_files.sh /path/to/php/directory_of_scripts</nowiki>}}
