Hello list; Was testing the time command. These problems came to light. time [-al] [-h | -p ] utility-name issuing time -h custom.refresh results in error message -h: Command not found issuing time -p custom.refresh results in error message -p: Command not found The DESCRIPTION says, The time utility executes and times the specified utility. After the utility finishes, time writes to the standard error stream, (in seconds): the total time elapsed, the time used to execute the utility process and the time consumed by system overhead. issuing time custom.refresh results in this output 0.089u 0.469s 0:01.44 37.5% 32+181k 64+137io 709pf+0w so based on the description 0.089u = the total time elapsed 0.469s = the time used to execute the utility [ie custom.refresh] 0:01.44 = time consumed by system overhead These 3 figures do not cross foot balance. Shouldn't time consumed by system overhead + the time used to execute the utility = the total time elapsed? so that leaves 37.5% and 32+181k 64+137io 709pf+0w without any description of what it is and no explanation of what the u suffix of 0.089u means or the s suffix of 0.469s means. The time command description already states [in seconds]. Can anyone shed some light on these problems?
