normally they are combined. 142.It Fl m 143Print per-user statistics rather than per-command statistics. 144.It Fl n 145Sort by number of calls. 146.It Fl q 147Create no output other than error messages. 148.It Fl r 149Reverse order of sort. 150.It Fl s 151Truncate the accounting files when done and merge their data 152into the summary files. 153.It Fl t 154For each command, report the ratio of real time to the sum 155of user and system cpu times. 156If the cpu time is too small to report, ``*ignore*'' appears in 157this field. 158.It Fl u 159Superseding all other flags, for each entry 160in the accounting file, print the user ID, total seconds of cpu usage, 161total memory usage, number of I/O operations performed, and 162command name. 163.It Fl v Ar cutoff 164For each command used 165.Ar cutoff 166times or fewer, print the command name and await a reply 167from the terminal. 168If the reply begins with ``y'', add 169the command to the category ``**junk**''. 170This flag is 171used to strip garbage from the report. 172.El 173.Pp 174By default, per-command statistics will be printed. 175The number of 176calls, the total elapsed time in minutes, total cpu and user time 177in minutes, average number of I/O operations, and CPU-time 178averaged core usage will be printed. 179If the 180.Fl m 181option is specified, per-user statistics will be printed, including 182the user name, the number of commands invoked, total cpu time used 183(in minutes), total number of I/O operations, and CPU storage integral 184for each user. 185If the 186.Fl u 187option is specified, the uid, user and system time (in seconds), 188CPU storage integral, I/O usage, and command name will be printed 189for each entry in the accounting data file. 190.Pp 191If the 192.Fl u 193flag is specified, all flags other than 194.Fl q 195are ignored. 196If the 197.Fl m 198flag is specified, only the 199.Fl b , 200.Fl d , 201.Fl i , 202.Fl k , 203.Fl q , 204and 205.Fl s 206flags are honored. 207.Sh FILES 208.Bl -tag -width /var/account/usracct -compact 209.It Pa /var/account/acct 210raw accounting data file 211.It Pa /var/account/savacct 212per-command accounting summary database 213.It Pa /var/account/usracct 214per-user accounting summary database 215.El 216.Sh EXIT STATUS 217.Ex -std 218.Sh SEE ALSO 219.Xr lastcomm 1 , 220.Xr acct 5 , 221.Xr ac 8 , 222.Xr accton 8 223.Sh CAVEATS 224While the behavior of the options in this version of 225.Nm 226was modeled after the original version, there are some intentional 227differences and undoubtedly some unintentional ones as well. 228In 229particular, the 230.Fl q 231option has been added, and the 232.Fl m 233option now understands more options than it used to. 234.Pp 235The formats of the summary files created by this version of 236.Nm 237are very different from the those used by the original version. 238This is not considered a problem, however, because the accounting record 239format has changed as well (since user ids are now 32 bits). 240.Sh AUTHORS 241.An Chris G. Demetriou Aq cgd@postgres.berkeley.edu 242.Sh BUGS 243The number of options to this program is absurd, especially considering 244that there's not much logic behind their lettering. 245.Pp 246The field labels should be more consistent. 247.Pp 248The VM system does not record the CPU storage integral. 249
