PROF(1) General Commands Manual PROF(1) NAME prof - display profile data SYNOPSIS prof [ option ... ] [ a.out [ mon.out ... ] ] DESCRIPTION Prof interprets files produced by monitor(3) or the -p option of cc or f77. The symbol table in the named object file by default) is read and correlated with the profile file by default). For each symbol, the percentage of time spent executing between that symbol and the next is printed (in decreasing order), together with the time spent there and the number of times that routine was called. If more than one profile file is specified, the output represents the sum of the profiles. Zero call counts are tallied for subroutines not compiled with option -p. The flag -p must be passed to the loader to get the profiling out- put written. Options are: -l Sort the output by symbol value. -n Sort the output by number of calls. -s Produce a summary profile file in -v -low -high Produce a graphic profile on the standard output for display by the plot(1) filters. Optional numbers low and high, by default 0 and 100, select a percentage of the profile to be plotted. -z Include routines with zero usage in the output. FILES for profile for namelist for summary profile SEE ALSO time(1), lcomp(1), monitor(3), getopt(3), profil(2), plot(1), cc(1), f77(1) BUGS Beware of quantization errors. Prof is confused by f77, which puts the entry points at the bottom of subroutines and functions. Option -v has been disabled. PROF(1)
