`flock` implements a thread-safe file lock.

It also includes a non-blocking `TryLock()` function to allow locking without blocking execution.

## Installation

```bash

go get -u github.com/gofrs/flock

```

## Usage

```go

import "github.com/gofrs/flock"

fileLock := flock.New("/var/lock/go-lock.lock")

locked, err := fileLock.TryLock()

if err != nil {

	// handle locking error

}

if locked {

	// do work

	fileLock.Unlock()

}

```

For more detailed usage information take a look at the package API docs on

[GoDoc](https://pkg.go.dev/github.com/gofrs/flock).
