A CLI tool is a bash script that creates multiple copies of a specified file, renaming each copy with an incrementing number.

copy-file.sh

#!/bin/bash

# Check if the required arguments are provided
if [ $# -ne 2 ]; then
  echo "Usage: ${0##*/} <file-path> <copy-count>"
  exit 1
fi

# Assign the arguments to variables
file_path=$1
copy_count=$2

# Check if the file exists
if [ ! -f "$file_path" ]; then
  echo "Error: File not found: $file_path"
  exit 1
fi

# Get the file name and directory
file_name=$(basename "$file_path")
file_dir=$(dirname "$file_path")

# Generate the copies
for ((i=1; i<=$copy_count; i++)); do
  new_file_name="${file_name%.${file_name##*.}}_${i}.${file_name##*.}"
  cp "$file_path" "$file_dir/$new_file_name"
done

Tip

To rename the original file by appending it with _0 to make it on top of the sequence, you can add below code at the end of the copy-file.sh script

new_file_name="${file_name%.${file_name##*.}}_0.${file_name##*.}"
mv "$file_path" "$file_dir/$new_file_name"
