Real programmers and quiche eaters

Good essay. I'd never heard of TECO so wiki'ed it. This is how to change the "hello" in "helloWorld.C" into "goodbye":

*EBhello.c$$ - Open file for read/write with backup
*P$$ - Read in the first page
*SHello$0TT$$ - Search for "Hello" and print the line

printf("Hello world!\n");  - The line

*-5DIGoodbye$0TT$$ - Delete "Hello", insert "Goodbye", and print the line

printf("Goodbye world!\n"); - The updated line

*EX$$ - Copy the remainder of the file and exit

I always thought vi was bad enough...
