Master Foo and the Ten Thousand Lines

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Master Foo once said to a visiting programmer: “There is more Unix-nature in

one line of shell script than there is in ten thousand lines of C.”

The programmer, who was very proud of his mastery of C, said: “How can this be?

C is the language in which the very kernel of Unix is implemented!”

Master Foo replied: “That is so. Nevertheless, there is more Unix-nature in one

line of shell script than there is in ten thousand lines of C.”

The programmer grew distressed. “But through the C language we experience the

enlightenment of the Patriarch Ritchie! We become as one with the operating

system and the machine, reaping matchless performance!”

Master Foo replied: “All that you say is true. But there is still more

Unix-nature in one line of shell script than there is in ten thousand lines of

C.”

The programmer scoffed at Master Foo and rose to depart. But Master Foo nodded

to his student Nubi, who wrote a line of shell script on a nearby whiteboard,

and said: “Master programmer, consider this pipeline. Implemented in pure C,

would it not span ten thousand lines?”

The programmer muttered through his beard, contemplating what Nubi had written.

Finally he agreed that it was so.

“And how many hours would you require to implement and debug that C program?”

asked Nubi.

“Many,” admitted the visiting programmer. “But only a fool would spend the time

to do that when so many more worthy tasks await him.”

“And who better understands the Unix-nature?” Master Foo asked. “Is it he who

writes the ten thousand lines, or he who, perceiving the emptiness of the task,

gains merit by not coding?”

Upon hearing this, the programmer was enlightened.
