How to enclose each line in single/double quote and end with comma except for the last line should not have a comma?

 You can achieve this by using a simple loop in a scripting language like Bash or Python. Here's an example in Bash:

```bash

#!/bin/bash

# Your input file

input_file="your_input.txt"

# Output file

output_file="output.txt"

# Counter to track the line number

line_number=0

# Start by creating an empty output file

> "$output_file"

# Read the input file line by line

while IFS= read -r line; do

  # Increment the line number

  ((line_number++))

  

  # Check if it's the last line

  if [ $line_number -eq $(wc -l < "$input_file") ]; then

    # If it's the last line, enclose in quotes without a comma

    echo "\"$line\"" >> "$output_file"

  else

    # For all other lines, enclose in quotes and add a comma

    echo "\"$line\"," >> "$output_file"

  fi

done < "$input_file"

```

This script reads each line from the `input_file`, encloses it in double quotes, and adds a comma. For the last line, it encloses it in double quotes without a comma. The output is saved in the `output_file`.

Make sure to replace `"your_input.txt"` with the path to your input file and `"output.txt"` with the desired output file name.
