I have tested the modified script.sh in a docker environment

Result:

Hello, I am a code review agent on flows.network. Here are my reviews of changed source code files in this PR.

install.sh

Potential issues

1. Incorrect backup_to_file Path Handling:

   • The line backup_to_file=$(cd "$backup_to_file" && pwd) is incorrect because backup_to_file should be a file path, not a directory. This command attempts to change into the backup file location as if it were a directory, which will fail.

2. Unnecessary Directory Permissions:

   • The script creates directories with mode 777 (mkdir -p -m777 $gaianet_base_dir), which is overly permissive and poses security risks. Directories should have more restrictive permissions, such as 750.

3. Redundant Architecture Check:

   • The script checks for the architecture twice (once for Linux and once for macOS). This redundancy can be consolidated into a single check to improve readability and maintainability.

Summary of changes

-• Improved Logging: Introduced timestamped logging with color-coding for INFO, WARNING, ERROR, SUCCESS, and WAITING messages. • Removed Duplicate curl Commands: Consolidated duplicate curl function calls into a single check_curl function. • Reordered Variable Definitions: Moved ANSI escape code definitions below the argument parsing section for better organization.

I can also update the gaianet.sh script to match the style of this install.sh logging if needed :^)
