TIMES(P) POSIX Programmer's Manual TIMES(P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAMEtimes - write process timesSYNOPSIStimesDESCRIPTION
The times utility shall write the accumulated user and system times for
the shell and for all of its child processes, in the following POSIX
locale format:
"%dm%fs %dm%fs\n%dm%fs %dm%fs\n", <shell user minutes>,
<shell user seconds>, <shell system minutes>,
<shell system seconds>, <children user minutes>,
<children user seconds>, <children system minutes>,
<children system seconds>
The four pairs of times shall correspond to the members of the
<sys/times.h> tms structure (defined in the Base Definitions volume of
IEEE Std 1003.1-2001, Chapter 13, Headers) as returned by times():
tms_utime, tms_stime, tms_cutime, and tms_cstime, respectively.
