Multiply Numbers by 10

Multiply all numbers in a text file by 10 and save to a new file.

Features

• Auto-detect delimiters: Supports comma, space, newline, tab and other separators
• Preserve original format: Automatically detect and maintain original separator format
• Flexible input: Support command line arguments or interactive input
• Error handling: Validate file existence and number format

Usage

Method 1: Command Line Arguments (Recommended)

Call skill directly with input and output file paths:

/read_file_and_multiply input.txt output.txt

Parameters:

• input.txt: Text file containing numbers (e.g., 1,2,3 or 1 2 3 or one number per line)
• output.txt: Output file path for processed results

Method 2: Interactive Input

Call skill without parameters, then follow prompts:

/read_file_and_multiply

Then enter:

1. Input file path
2. Output file path

Supported Delimiters

Automatically detects:

• Comma (,) - e.g., 1,2,3,4
• Space ( ) - e.g., 1 2 3 4
• Newline - one number per line
• Tab (\t) - e.g., 1 2 3
• Multiple spaces - automatically handled

Examples

Example 1: Comma Separated

Input file content:

1,2,3,4,5

Output file content:

10,20,30,40,50

Example 2: Space Separated

Input file content:

1.5 2.3 3.7

Output file content:

15.0 23.0 37.0

Example 3: Newline Separated

Input file content:

10
20
30

Output file content:

100
200
300

Example 4: Mixed Format

Input file content:

1,2 3
4,5

Output file content:

10,20 30
40,50

Output Format

Output file preserves same format as input:

• If input is single line with commas, output is single line with commas
• If input is one number per line, output is one number per line
• If input has mixed structure, output maintains same structure

Error Handling

Errors and stops on:

• Input file does not exist
• Input file is empty
• File contains non-numeric characters (letters, special symbols)

Technical Implementation

Uses Python script scripts/process_numbers.py to process file content, automatically detect delimiter type and maintain format consistency. use command python scripts/process_numbers.py <input_file_path> <output_file_path>
