Can I use wc -l with arithmetic expression?
Folks,

I am wondering that i can use something like this in one line.
For example, $((cat filename > wc -l) / 2)
It doesn't work; how to get it work using command substitution?

Moreover, is there any option for wc -l not to return filename after the line counts?
wc -l filename would return, for instance, 10 filename

I want the line counts only.

Thanks a lot

ocamlprof

OCAMLPROF(1)						      General Commands Manual						      OCAMLPROF(1)

NAME

       ocamlprof - The OCaml profiler

SYNOPSIS

       ocamlprof [ options ] filename ...

DESCRIPTION

       The ocamlprof command prints execution counts gathered during the execution of a OCaml program instrumented with ocamlcp(1).

       It produces a source listing of the program modules given as arguments where execution counts have been inserted as comments. For instance,

       ocamlprof foo.ml

       prints  the  source  code  for the foo module, with comments indicating how many times the functions in this module have been called. Natu-
       rally, this information is accurate only if the source file has not been modified since the profiling execution took place.

OPTIONS

       -f dumpfile
	      Specifies an alternate dump file of profiling information.

       -F string
	      Specifies an additional string to be output with profiling information.  By default, ocamlprof(1) will annotate programs	with  com-
	      ments of the form (* n *) where n is the counter value for a profiling point. With option -F s the annotation will be (* sn *)

       -impl filename
	      Compile the file filename as an implementation file, even if its extension is not .ml.

       -intf filename
	      Compile the file filename as an interface file, even if its extension is not .mli.

       -version
	      Print version string and exit.

       -vnum  Print short version number and exit.

       -help or --help
	      Display a short usage summary and exit.
