UNIX for Beginners Questions & Answers

You're welcome.

Wow! That wasn't at all what I was expecting. From your sample data, I thought you were looking for lowercase words create and from at the start of a line of input. But instead you are looking for an uppercase CREATE followed by a <space> anywhere on a line and are looking for any of the characters f, F, m, M, o, O, r, R, or | followed by a <space> followed by any number of characters that includes an @.

What output would you hope to get from the input file:

Code:

reCREATE xyzzy
| @
f @
O x@y
r v@w
from: a@b

Does it surprise you that the only line in the above sample that is not printed at least once by your code is the last line? Is that what you want your code to do?
