On Linux or Mac, try `wc' (the first number printed is the one you want). To
omit whitespace and comments, you could pipe the file through grep -v first:
$ grep -vxE '[[:space:]]*(;.*)?' file.clj | wc
117 449 3567
That regular expression matches any line that consists of zero or more
whitespace characters, followed by an optional suffix that starts with a
semicolon. Not perfect, but should be good enough for most purposes.
(Cue the old "now you have two problems" joke about regexes…)
