Specifying program and data files to lprof

By default, lprof expects the profiled program to be called a.out, and the data file, a.out.cnt.

To run lprof on a program with a name other than a.out, specify the name after the -o option. For example:

   $ lprof -o sample

You can specify a data file other than sample.cnt by using the -c option. For example:

   $ lprof -c newdata.cnt
