Could you explain what is happening so that I won't ask the same stupid question next time, and so I'll be able to explain it to other people... ?

This Perl one-liner will read a line at a time from the files provided to it (by the shell by expanding Event*; I hope there are only regular files matching that pattern). The name of the current input file will be in the variable $ARGV. To identify the first line of a file, the variable $prev is used. When this variable is not the same as $ARGV, it means the first line of the new file. In this line, the required substitution is made. That is, the first block of data between { and } is matched (through the non-greedy quantifier *?; for more info, use Google) and captured. This is then used (as \1), followed by the required string, in the replacement string.

Is there a way to check to see if a file ALREADY has the additional line in it so that it doesn't add another line?
