I like to use the unix command grep -c (print a count of matches) on multiple files at a time, but it displays the count for each file. I want a total count, so I call on Perl. Pipe the output of grep -c PATTERN file1 file2 ... to this snippet.

update: don't use this, use blakem's better solution below.
perl -anF: -e '$sum += $F[-1] }{ print $sum.$/'
