451+
452+<CODE>time</CODE> uses a <EM>format string</EM> to determine which information to
453+display about the resources used by the command it runs. See section <A HREF="time.html#SEC3">1.2 The Format String</A>, for the interpretation of the format string contents.
454+</P>
455+<P>
456+
457+You can specify a format string with the command line options listed
458+below. If no format is specified on the command line, but the
459+<CODE>TIME</CODE> environment variable is set, its value is used as the format
460+string. Otherwise, the default format built into <CODE>time</CODE> is used:

527+The <EM>format string</EM> controls the contents of the <CODE>time</CODE> output.

532+
533+A backslash introduces an <EM>escape</EM>, which is translated
534+into a single printing character upon output. The valid escapes are
535+listed below. An invalid escape is output as a question mark followed
536+by a backslash.

557+<CODE>time</CODE> always prints a newline after printing the resource use

559+character (or `<SAMP>\n</SAMP>').
560+</P>
561+<P>
562+
563+A resource specifier consists of a percent sign followed by another
564+character. An invalid resource specifier is output as a question mark
565+followed by the invalid character. Use `<SAMP>%%</SAMP>' to output a literal
566+percent sign.
567+</P>
568+<P>
569+
570+The resource specifiers, which are a superset of those recognized by the
571+<CODE>tcsh</CODE> builtin <CODE>time</CODE> command, are listed below. Not all
572+resources are measured by all versions of Unix, so some of the values
573+might be reported as zero (see section <A HREF="time.html#SEC10">1.5 Accuracy</A>).

943+<!--docid::SEC10::-->
944+<P>
945+
946+The elapsed time is not collected atomically with the execution of the
947+program; as a result, in bizarre circumstances (if the <CODE>time</CODE>
948+command gets stopped or swapped out in between when the program being
949+timed exits and when <CODE>time</CODE> calculates how long it took to run), it
950+could be much larger than the actual execution time.
951+</P>
952+<P>
953+
954+When the running time of a command is very nearly zero, some values
955+(e.g., the percentage of CPU used) may be reported as either zero (which
956+is wrong) or a question mark.
957+</P>
958+<P>
959+
960+Most information shown by <CODE>time</CODE> is derived from the <CODE>wait3</CODE>
961+system call. The numbers are only as good as those returned by
962+<CODE>wait3</CODE>. Many systems do not measure all of the resources that
963+<CODE>time</CODE> can report on; those resources are reported as zero. The
964+systems that measure most or all of the resources are based on 4.2 or
965+4.3BSD. Later BSD releases use different memory management code that
966+measures fewer resources.
967+</P>
968+<P>
969+
970+On systems that do not have a <CODE>wait3</CODE> call that returns status
971+information, the <CODE>times</CODE> system call is used instead. It provides
972+much less information than <CODE>wait3</CODE>, so on those systems <CODE>time</CODE>
973+reports most of the resources as zero.
974+</P>
975+<P>
976+
977+The `<SAMP>%I</SAMP>' and `<SAMP>%O</SAMP>' values are allegedly only &quot;real&quot; input
978+and output and do not include those supplied by caching devices. The
979+meaning of &quot;real&quot; I/O reported by `<SAMP>%I</SAMP>' and `<SAMP>%O</SAMP>' may be
980+muddled for workstations, especially diskless ones.
