LinkFinder

LinkFinder is a Go program designed to search through file systems for symbolic links (symlinks) and hard links related to a specified target file. This tool offers flexibility by allowing users to specify whether to search for symlinks, hard links, or both, and to define a starting path for the search.

Features

• Search for symlinks and/or hard links throughout a file system.
• Configure the search to specifically find either symlinks, hard links, or both.
• Specify a starting path to narrow down the search area for efficiency.
• Concurrently process files using multiple goroutines for faster search operations.

Usage

To use LinkFinder, compile the Go source file and run the executable with the desired command-line options.

lfinder [-s|-h] [-p path] <target_file_name>

Command-Line Options

• -s: Find symlinks only. Searches for symbolic links that point to the specified target file.
• -h: Find hard links only. Searches for hard links that reference the same inode as the target file.
• -p: Specify the path to start the search from. Defaults to the root directory (/) if not set.

Positional Arguments

• <target_file_name>: Specify the name of the target file to search for links. This argument is required.

Example

Finding all symlinks pointing to example.txt starting from the /home/user directory:

lfinder -s -p /home/user example.txt

Implementation Details

• Concurrently processes files by spawning multiple worker goroutines, enhancing the search speed.
• Utilizes channels for job distribution among workers and for collecting results.
• Handles both symlinks and hard links by checking file metadata and inode information.
• Employs a straightforward command-line interface using Go's flag package for ease of use.

Building from Source

To compile LinkFinder from source, ensure you have a Go development environment set up, then run:
