Pipes in Unix Based Operating Systems

Unix based operating systems like Linux offer a unique approach to join two discrete commands, and generate a new command using the concept of pipe(lines). For example, consider command1|command2. Here, whatever output is generated by the first command becomes the standard input for the second command.
Despite significant advances in asthma therapy and objective monitoring, patients continue to die from their asthma, many needlessly. The majority of fatal asthma attacks develop over hours to days, making it possible to prevent these deaths. High risk asthmatics need to be identified at both primary and secondary care levels. Any adverse behavioural or psychological features should be addressed using a multi-disciplinary approach and at the same time an asthma management plan put in place. High risk asthmatics should be reviewed at regular intervals by a respiratory physician with a special interest in severe asthma.
How do we discern the difference between a game that actually features compelling design and a game the presents an appealing package? The Mass Effect series is arguably one of the best gaming sagas ever published. I'm definitely a fan.

I think it's fair to say that folks who have acquired the full 1000 gamerscore (Or "Platted" for my PS3 fans) in Final Fantasy XIII or people who acquired the "Little Rocket Man" achievement in Half Life 2 are slightly obsessive compulsive. If you have no clue what the "Little Rocket Man" achievement is, I'm probably not talking about you. Over the past few years, you could easily toss me into the OC bracket.
Asthma is a disease whose main characteristic is the shortness of breath and we can see most of the patients generally panting and gasping for breath after a moderately rigorous physical exercise.
