A Standard for Robot Exclusion: "Examples
The following example '/robots.txt' file specifies that no robots should visit any URL starting with '/cyberworld/map/' or '/tmp/', or /foo.html:


# robots.txt for http://www.example.com/

User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space
Disallow: /tmp/ # these will soon disappear
Disallow: /foo.html



This example '/robots.txt' file specifies that no robots should visit any URL starting with '/cyberworld/map/', except the robot called 'cybermapper':


# robots.txt for http://www.example.com/

User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space

# Cybermapper knows where to go.
User-agent: cybermapper
Disallow:
