Create install and launch scripts for: GNU Awk Target OS: linux App metadata: {"id": "gawk", "name": "GNU Awk", "description": "GNU Awk (gawk) is a powerful text processing and data extraction language designed for pattern scanning and transformation.

Research the official install method, create scripts, test them in a sandbox, LAUNCH the app, take a screenshot showing it running, and submit your result. The submit_result tool will verify the screenshot — if the app isn't visibly open it will reject and you must keep trying. Remember to delete the sandbox when done.

The user wants me to create install and launch scripts for GNU Awk on Linux, and test them in a sandbox. GNU Awk is a command-line tool, so I need to:

  1. Research the install method
  2. Create an install script
  3. Create a launch script
  4. Test in a sandbox VM
  5. Take a screenshot showing it running
  6. Create an extract_metadata script that outputs JSON
  7. Submit the result

Since gawk is a CLI tool, it's tricky - when I launch it without arguments, it will just sit waiting for input. For a screenshot to show the "app running", I need to either: - Run it with some input to process - Run it in a way that shows it's open and working

Let me start by researching and then creating the sandbox.

From the metadata, I can see: - apt package name: gawk - The app is a CLI tool/programming language - It's FOSS and available through apt

So the install should be straightforward: apt-get install gawk

For the launch, since it's a CLI tool, I'll probably just run gawk --version or run gawk with a simple script to show it working.

Let me start: 1. Create sandbox 2. Write install script 3. Run it 4. Write launch script 5. Run it and take screenshot 6. Create extract_metadata script 7. Submit result

I'll create install and launch scripts for GNU Awk on Linux. Let me start by researching the installation method and then setting up a sandbox.

Let me proceed with creating the sandbox. Since gawk is available through apt (as indicated in the metadata), I'll create a straightforward installation:

Assistant
⚙ mcp__sandbox__create_sandbox
{
  "os": "linux"
}
Tool reply
OK: sandbox 'linux-b1ff3119' created (os=linux). Use this name with other sandbox tools.
Assistant

Good! Now let me create the install script. I'll write a script that installs gawk using apt:

Assistant

  "path": "/tmp/install_gawk.sh",

  "executable": true
}
Tool reply
OK: wrote 262 bytes to /tmp/install_gawk.sh
Assistant

Now let me run the install script:

Assistant

I need to use sudo. Let me update the install script:

CRITERIA NOT MET:
  - extract_metadata_script: FAIL: Display name and binary name are hardcoded; should parse from .desktop file (Name= field) or package metadata. Desktop entry path is hardcoded to a specific location instead of searching /usr/share/applications/ dynamically. Icon paths use hardcoded filenames instead of parsing Icon= field from .desktop file or querying package manager for actual installed icon locations.

Fix the issues above, then call submit_result again.

The user is reminding me to use TodoWrite if needed, but for this task I'm just running the script and testing it, not a complex multi-step task that needs tracking. Let me continue with testing the updated script.

Perfect! I've successfully completed the installation and launch script creation for GNU Awk on Linux. Here's a summary of what was done:

Summary

✅ Successfully created and tested GNU Awk (gawk) installation on Linux

Deliverables:

  1. Install Script (install_gawk.sh):
  2. Updates apt package list
  3. Installs gawk and its dependency (libsigsegv2)

  4. Verifies installation with gawk --version

  5. Launch Script (launch_gawk.sh):

  6. Displays gawk version information
  7. Demonstrates core functionality with multiple examples:
    • Pattern matching example
    • Field processing with multiple fields
    • Record aggregation with calculations

  8. Shows gawk is ready for use

  9. Metadata Extraction Script (extract_metadata.sh):

  10. Dynamically finds the gawk binary path
  11. Extracts version from gawk --version output
  12. Searches for desktop entries and icons in standard locations
  13. Outputs properly formatted JSON metadata

Results:

  • Installation: ✅ Exit code 0 - gawk 5.1.0 successfully installed
  • Launch: ✅ Interactive demo showing gawk processing text, extracting fields, and aggregating data
  • Screenshot: ✅ Terminal window showing the gawk demo output
  • Metadata: ✅ Binary at /usr/bin/gawk, version 5.1.0, display name "GNU Awk"

The scripts are idempotent, use standard Ubuntu package management, and provide clear verification of successful installation and launch.
