Hi.
The brackets (braces) are backslashed to give them special meaning (they would otherwise be literal braces).
^ matches something at the beginning of the line (an empty string because it doesn't remove anything from the pattern space), but has special meaning if it's the first character after a square braclet [ (in which case it negates the match (i.e. ^[0-9] means match a number at the start of a line, whereas ^[^0-9] means don't match a number at the start of a line, and [^0-9] means don't match a number, wherever [^0-9] appears in your expression).
In your expression ^.\{42\} means match 42 of any character starting at the beginning of the line, as DrSammy described.
