After the _c_o_m_m_a_n_d finishes, ttiimmee 12 writes to the standard error stream, (in seconds): the total time 13 elapsed, time consumed by system overhead, and the time used to execute 14 the _c_o_m_m_a_n_d process. 15 16 Available options: 17 18 --ll The contents of the _r_u_s_a_g_e structure are printed as well. 19 20 The csh(1) has its own and syntactically different builtin version of 21 ttiimmee.. The command described here is available as /_b_i_n/_t_i_m_e to csh users. 22 23BBUUGGSS 24 The granularity of seconds on micro processors is crude and can result in 25 times being reported for CPU usage which are too large by a second. 26 27SSEEEE AALLSSOO 28 csh(1) 29 30FFIILLEESS 31 /usr/include/sys/h/resource.h 32 33HHIISSTTOORRYY 34 A ttiimmee command appeared in Version 6 AT&T UNIX. 35 364th Berkeley Distribution April 23, 1991 1 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67
