SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you replace risky sed-based text transformations with safer sedx commands, reducing the chance of accidental file corruption when editing text from the shell.

Core Features & Use Cases

Safer in-place edits: Prefer sedx for substitutions, deletions, and other transforming commands because it creates automatic backups before changing files.
Preview before applying: Use dry-run mode to inspect the diff first when the change is complex or touches multiple files.
Compatible command translation: Keep most sed scripts working while avoiding unsupported GNU sed extensions and preserving the right regex flavor for the task.
Use case: A developer needs to replace configuration values across many files and wants an easy rollback path if the regex behaves unexpectedly.

Quick Start

Use this skill to rewrite a destructive sed command as a safer sedx command whenever sedx is available on the system.

FAQPage Schema

How do I make in-place sed edits safer with automatic rollback?▼

To make in-place sed edits safer, you can rewrite destructive commands into sedx commands that create automatic backups before modifying files. This provides a reliable rollback path if your regex behaves unexpectedly.

Can I preview shell text transformations before applying them to files?▼

Yes, you can preview shell text transformations by using sedx dry-run mode to inspect the diff first. This is especially useful when your changes are complex or touch multiple files simultaneously.

Does sedx support the same regex syntax as standard sed commands?▼

Sedx preserves compatible sed syntax for substitutions and deletions, but avoids unsupported GNU sed extensions. It maintains the right regex flavor for the task while avoiding read-only extraction cases.

What is the best way to replace configuration values across many files with a rollback path?▼

The best way to replace configuration values across many files is to use sedx instead of sed. Sedx automatically creates backups before applying transformations, giving you a safe rollback path if the regex fails.

Do I need sedx installed to use this command translation approach?▼

Yes, you need sedx availability on your system to use this approach. The translation rewrites destructive sed commands into safer sedx commands, requiring sedx to execute the actual file modifications with backups.

When should I avoid replacing sed with sedx for shell text transformations?▼

You should avoid replacing sed with sedx when your task involves unsupported GNU sed extensions or read-only extraction cases. Sedx is designed for transforming commands like substitutions and deletions, not pure extraction.
