What I used in the one liner is called Regular Expression.
The slashes are just separators, the syntax is: s/Regex/replacement/ ^ matches the very start of the string(a line in data.txt). . matches a single character(any character). (\d{4})\d represents number from 0 to 9, 4 in the curly braces means the pattern will match 4 numbers, the outer braces capture the 4 numbers(yr you want), this is called a group in Regular Expression. (\d{3}) is roughly the same as the previous pattern. $1 $2 prints the 1st and 2nd groups captured by the pattern.
For your last question, yes, Perl can easily achieve what you want but may not be as easy as the previous command, shouldn't be complicated though
