redactor

A command-line utility that wraps program execution and redacts sensitive strings from terminal output.

Installation

go install github.com/iamjsd/redactor@latest

Or build from source:

go build -o redactor

Usage

redactor "<redactions>" <command> [args...]

Where <redactions> is a newline-separated list of strings to redact from the output.

Example

# Redact a password from command output
redactor "my-secret-password" cat config.txt

# Redact multiple strings
redactor $'secret1\nsecret2\napi-key-123' ./my-script.sh

Redacted strings are replaced with asterisks (*) of equal length.

How It Works

1. Spawns the target command in a pseudo-terminal (PTY)
2. Intercepts all output line by line
3. Replaces any occurrences of redaction strings with asterisks
4. Passes through stdin and handles terminal resize signals
