Hello,
I need to count the number of lines in a large number of UNIX text files,
most of which are fairly large. I need help coming up with an efficient
implementation of a line-count program. A naive implementation like
length(readlines("foo.txt")) is very slow (notice how this loads the whole
file into memory just to count newlines). I imagine that it should be
possible to count the number of newline characters quickly, like what the
"wc" command does, but I can't figure out how. Does anyone have any ideas?
Thanks for the help.
Daniel.
