+# git-fsck-dirs
+
+A utility to check multiple Git repositories for corruption
+using `git fsck`.
+
+## Overview
+
+`git-fsck-dirs` scans all subdirectories within a specified path
+and performs a `git fsck` operation on each Git repository found.
+This helps identify corrupted repositories or those with integrity
+issues.
+
+## Features
+
+- Recursively checks all Git repositories in the given directory
+- Provides a summary of repositories checked and any issues found
+- Filters out common version control directories (.git, .svn, etc.)
+- Supports verbose and debug modes
+
+## Usage
+
+```bash
+git-fsck-dirs [path] [errors_file] [repo_count_file]
+git fsck-dirs [path] [errors_file] [repo_count_file]
+```
+
+### Arguments
+
+- `path`: Directory to scan (defaults to current directory)
+- `errors_file`: Path to save errors (defaults to /tmp/git-fsck-errors.txt)
+- `repo_count_file`: Path to save repository count
+  (defaults to /tmp/git-fsck-repo-count.txt)
+
+### Environment Variables
+
+- `VERBOSE=1`: Enable verbose output
+- `DEBUG=1`: Enable debug mode (shows executed commands)
+
+## Examples
+
+Check repositories in the current directory:
+
+```bash
+git fsck-dirs
+git-fsck-dirs
+```
+
+Check repositories in a specific directory:
+
+```bash
+git fsck-dirs ~/projects
+git-fsck-dirs ~/projects
+```
+
+Enable verbose output:
+
+```bash
+VERBOSE=1 git-fsck-dirs
+```
