Maybe something like this?

Code:
$
$
$ perl -lne 'die if !/^ : /; print "You entered => \"$_\""'
 : hello
You entered => " : hello"
 : world
You entered => " : world"
 : the quick brown fox jumps over the lazy dog
You entered => " : the quick brown fox jumps over the lazy dog"

Died at -e line 1, <> line 4.
