Well consider this:

grep CTCTL < somefile

This read read somefile and display only the lines that contain the string "CTCTL".

But just:
grep CTCTL
all by itself is a problem. It will read lines that you type in. Then if you had CTCTL somewhere in the line, it would repeat the line. Not my idea of a good time.
