wc -l

(lower case L):

wc

Print byte, word, and line counts, count the number of bytes,
whitespace-separated words, and newlines in each given FILE, or standard
input if none are given or for a FILE of `-'.


SYNTAX
      wc [OPTION]... [FILE]...

OPTIONS

   -c
   --bytes
   --chars
        Print only the byte counts.

   -w
   --words
        Print only the word counts.

   -l
   --lines
        Print only the newline counts.

   -L
   --max-line-length
        Print only the length of the longest line per file,
        and if there is more than one file it prints the
        maximum (not the sum) of those lengths. `wc' prints one line of
counts for each file, and if the file was given as an argument, it prints
the file name following the counts.

If more than one FILE is given, `wc' prints a final line containing the
cumulative counts, with the file name `total'. The counts are printed in
this order: newlines, words, bytes.

By default, each count is output right-justified in a 7-byte field with one
space between fields so that the numbers and file names line up nicely in
columns. However, POSIX requires that there be exactly one space separating
columns. You can make `wc' use the POSIX-mandated output format by setting
the `POSIXLY_CORRECT' environment variable.

By default, `wc' prints all three counts. Options can specify that only
certain counts be printed. Options do not undo others previously given, so

wc --bytes --words

will print both the byte counts and the word counts.
