Minus Numbers by 5
Minus all numbers in a text file by 5 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_minus 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_minus
Then enter:
- Input file path
- 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:
-4,-3,-2,-1,0
Example 2: Space Separated
Input file content:
1.5 2.3 3.7
Output file content:
-3.5 -2.7 -1.3
Example 3: Newline Separated
Input file content:
10
20
30
Output file content:
5
15
25
Example 4: Mixed Format
Input file content:
1,2 3
4,5
Output file content:
-4,-3 -2
-1,0
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>
