Summary option

Summary option

You can obtain a summary report of the profile data by using the -s option: 

   $ lprof -s -c sample.cnt
Because a source listing is not produced with lprof -s, the -r and -I options do not need to be specified: lprof needs only to find the data file. The following example shows output produced with the -s option: 
   Coverage Data Source: a.out.cnt
   Date of Coverage Data Source: Wed Sep 18 16:42:19 1991
   Object: ./a.out
