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:

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

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

$ process_tail $(pgrep PROCESS_NAME)
