gprof linux command

gprof

gprof [options] [object_file]

Display the profile data for an object file. The file's symbol table is compared with the call graph profile file gmon.out (previously created by compiling with gcc -pg).

Options

-a

Do not display statically declared functions. Since their information might still be relevant, append it to the information about the functions loaded immediately before.

-b

Do not display information about each field in the profile.

-c

Consult the object file's text area to attempt to determine the program's static call graph. Display static-only parents and children with call counts of 0.

-e routine

Do not display entries for routine and its descendants.

-f routine

Print only routine, but include time spent in all routines.

-k from to

Remove arcs between the routines from and to.

-s

Summarize profile information in the file gmon.sum.

-v

Print version and exit.

-z

Include zero-usage calls.

-E routine

Do not display entries for routine and its descendants or include time spent on them in calculations for total time.

-F routine

Print only information about routine. Do not include time spent in other routines.
