# ProcessTail [![Build Status](https://travis-ci.org/hibariya/process_tail.svg?branch=master)](https://travis-ci.org/hibariya/process_tail)

https://github.com/hibariya/process_tail

## Description

ProcessTail traces other process' write(2) system call and copy its buffer.

So we can get other process outputs.

## Problems

* SEGV occurs infrequently

* Windows is not supported

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'process_tail'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install process_tail

## Usage

On Mac OSX, you'll have to use `sudo`.

### Get outputs as an IO object

```ruby

ProcessTail.each pid do |tid, fd, str|

  puts tid # pid or tid of this process (thread)

  puts fd  # File descripter number

  puts str # Output string

end

```

### Show outputs instantly

```bash

$ process_tail $(pgrep PROCESS_NAME)

```
