    of the signal which caused time to stop or abort
    (time-debian-non-normal-exit.patch).
  * struct rusage and sys/resource.h portability fix
    (time-debian-rusage-portability.patch, Debian#144819).
  * Add -q,--quiet functionality
    (time-debian-quiet.patch, Debian#56853).
  * Update bug reporting address
    (time-debian-bug-address.patch, Debian#542469).
  * Modernize the configure.in file to current autoconf style
    (time-debian-configure.patch).
  * Add a directory entry to the info page
    (time-debian-info-direntry.patch).
- Fix FSF address (time-fsf-address.patch).
- Update Summary.
- Rename time-1.7.diff to time-alpha.patch.

... And cherry pick changelog entries relevant to time. (forwarded request 198137 from sbrabec)

.SH DESCRIPTION
.B time
run the program
.I COMMAND
with any given arguments
.IR "ARG..." .
When
.I COMMAND
finishes,
.B time
displays information about resources used by
.I COMMAND
(on the standard error output, by default). If
.I COMMAND
exits with non\-zero status,
.B time
displays a warning message and the exit status.
.B time
determines which information to display about the resources used by the
.I COMMAND
from the string
.IR FORMAT .
If no format is specified on the command line, but the
.B TIME
environment variable is set, its value is used as the format.
Otherwise, a default format built into
.B time
is used.
Options to
.B time
must appear on the command line before
.IR COMMAND .
Anything on the command line after
.I COMMAND
is passed as arguments to
.IR COMMAND .
.SH OPTIONS
.TP
.BI \-o " FILE, " \-\-output= "FILE "
Write the resource use statistics to
.I FILE
instead of to the standard error stream. By default, this overwrites the
file, destroying the file's previous contents. This option is useful for
collecting information on interactive programs and programs that produce
output on the standard error stream.
.TP
.BR \-a ", " \-\-append ""
Append the resource use information to the output file instead of overwriting
it. This option is only useful with the `\-o' or `\-\-output' option.
.TP
.BI \-f " FORMAT, " \-\-format " FORMAT "
Use
.I FORMAT
as the format string that controls the output of
.BR time .
See the below more information.
.TP
.B \-\-help
Print a summary of the command line options and exit.
.TP
.BR \-p ", " \-\-portability ""
Use the following format string, for conformance with POSIX standard 1003.2:
real %e
user %U
sys %S
.TP
.BR \-v ", " \-\-verbose ""
Use the built\-in verbose format, which displays each available piece of
information on the program's resource use on its own line, with an English
description of its meaning.
.TP
.B \-\-quiet
Do not report the status of the program even if it is different from zero.
.TP
.BR \-V ", " \-\-version ""
Print the version number of
.B time
and exit.
.SH "FORMATTING THE OUTPUT"
The format string
.I FORMAT
controls the contents of the
.B time
output. The format string can be set using the `\-f' or `\-\-format', `\-v' or
`\-\-verbose', or `\-p' or `\-\-portability' options. If they are not
given, but the
.I TIME
environment variable is set, its value is used as the format string.
Otherwise, a built\-in default format is used. The default format is:
%Uuser %Ssystem %Eelapsed %PCPU (%Xtext+%Ddata %Mmax)k
%Iinputs+%Ooutputs (%Fmajor+%Rminor)pagefaults %Wswaps
The format string usually consists of `resource specifiers'
interspersed with plain text. A percent sign (`%') in the format
string causes the following character to be interpreted as a resource
specifier, which is similar to the formatting characters in the
.BR printf (3)
function.
A backslash (`\\') introduces a `backslash escape', which is
translated into a single printing character upon output. `\\t' outputs
a tab character, `\\n' outputs a newline, and `\\\\' outputs a backslash.
A backslash followed by any other character outputs a question mark
(`?') followed by a backslash, to indicate that an invalid backslash
escape was given.
Other text in the format string is copied verbatim to the output.
.B time
always prints a newline after printing the resource use
information, so normally format strings do not end with a newline
character (or `\en').
There are many resource specifications. Not all resources are
measured by all versions of Unix, so some of the values might be
reported as zero. Any character following a percent sign that is not
listed in the table below causes a question mark (`?') to be output,
followed by that character, to indicate that an invalid resource
specifier was given.
.\" No blank line between the resource specifiers below so that they
.\" are more compactly listed.
.PD 0
The resource specifiers, which are a superset of those recognized by the
.BR tcsh (1)
builtin `time' command, are:
.RS
.IP %
A literal `%'.
.IP C
Name and command line arguments of the command being timed.
.IP D
Average size of the process's unshared data area, in Kilobytes.
.IP E
Elapsed real (wall clock) time used by the process, in [hours:]minutes:seconds.
.IP F
Number of major, or I/O\-requiring, page faults that occurred while
the process was running. These are faults where the page has
actually migrated out of primary memory.
.IP I
Number of file system inputs by the process.
.IP K
Average total (data+stack+text) memory use of the process, in
Kilobytes.
.IP M
Maximum resident set size of the process during its lifetime, in
Kilobytes.
.IP O
Number of file system outputs by the process.
.IP P
Percentage of the CPU that this job got. This is just user +
system times divided by the total running time. It also prints
a percentage sign.
.IP R
Number of minor, or recoverable, page faults. These are pages
that are not valid (so they fault) but which have not yet been
claimed by other virtual pages. Thus the data in the page is
still valid but the system tables must be updated.
.IP S
Total number of CPU\-seconds used by the system on behalf of the
process (in kernel mode), in seconds.
.IP U
Total number of CPU\-seconds that the process used directly (in user
mode), in seconds.
.IP W
Number of times the process was swapped out of main memory.
.IP X
Average amount of shared text in the process, in Kilobytes.
.IP Z
System's page size, in bytes. This is a per\-system constant, but
varies between systems.
.IP c
Number of times the process was context\-switched involuntarily
(because the time slice expired).
.IP e
Elapsed real (wall clock) time used by the process, in seconds.
.IP k
Number of signals delivered to the process.
.IP p
Average unshared stack size of the process, in Kilobytes.
.IP r
Number of socket messages received by the process.
.IP s
Number of socket messages sent by the process.
.IP t
Average resident set size of the process, in Kilobytes.
.IP w
Number of times that the program was context\-switched voluntarily,
for instance while waiting for an I/O operation to complete.
.IP x
Exit status of the command.
.RS
.SH EXAMPLES
To run the command `wc /etc/hosts' and show the default information:
time wc /etc/hosts
To run the command `ls \-Fs' and show just the user, system, and total
time:
time \-f "\et%E real,\et%U user,\et%S sys" ls \-Fs
To edit the file BORK and have `time' append the elapsed time and
number of signals to the file `log', reading the format string from the
environment variable `TIME':
export TIME="\et%E,\et%k" # If using bash or ksh
setenv TIME "\et%E,\et%k" # If using csh or tcsh
time \-a \-o log emacs bork
Users of the
.B bash
shell need to use an explicit path in order to run the external
.B time
command and not the shell builtin variant. On system where
.B time
is installed in
.IR /usr/bin ,
the first example would become
/usr/bin/time wc /etc/hosts
.SH ACCURACY
The elapsed time is not collected atomically with the execution of
the program; as a result, in bizarre circumstances (if the
.B time
command gets stopped or swapped out in between when the program being
timed exits and when
.B time
calculates how long it took to run), it
could be much larger than the actual execution time.
When the running time of a command is very nearly zero, some values
(e.g., the percentage of CPU used) may be reported as either zero (which
is wrong) or a question mark.
Most information shown by
.B time
is derived from the
.BR wait3 (2)
system call. The numbers are only as good as
those returned by
.BR wait3 (2).
On systems that do not have a
.BR wait3 (2)
call that returns status information, the
.BR times (2)
system call is used instead. However, it provides much less information than
.BR wait3 (2),
so on those systems
.B time
reports the majority of the resources as zero.
The `%I' and `%O' values are allegedly only `real' input and output
and do not include those supplied by caching devices. The meaning of
`real' I/O reported by `%I' and `%O' may be muddled for workstations,
especially diskless ones.
.SH DIAGNOSTICS
The
.B time
command returns when the program exits, stops, or is terminated by a signal.
If the program exited normally, the return value of
.B time
is the return value of the program it executed and measured. Otherwise, the
return value is 128 plus the number of the signal which caused the program to
stop or terminate.
.SH AUTHOR
.B time
was written by David MacKenzie. This man page was added by Dirk Eddelbuettel
<edd@debian.org>, the Debian GNU/Linux maintainer, for use by the Debian
GNU/Linux distribution but may of course be used by others.
