gprof: Suppress profile field's description.

gprof

$ gprof -b

try on your machine

The command "gprof -b" is used to generate a profile of a program's execution time to analyze its performance.

Here's what each part of the command means:

"gprof" is the command itself, which stands for "GNU Profiler." It is a tool provided by the GNU project for profiling and analyzing the performance of programs.
"-b" is an option for gprof that specifies a batch mode. In batch mode, gprof generates a text file containing the profile data, instead of displaying it in an interactive format. This is useful when you want to automate the analysis of the profile data or process it further.

Running the command "gprof -b" on a program will generate a file (usually named "gmon.out") that contains the profiling data. This data can then be analyzed using other tools or visualizers to understand the program's execution time distribution, including which functions take the most time and how they are called.
