TIME(1) 						    BSD General Commands Manual 						   TIME(1)

NAME
time -- time command execution SYNOPSIS
time [-lp] utility DESCRIPTION
The time utility executes and times utility. After the utility finishes, time writes the total time elapsed, the time consumed by system overhead, and the time used to execute utility to the standard error stream. Times are reported in seconds. Available options: -l The contents of the rusage structure are printed. -p The output is formatted as specified by IEEE Std 1003.2-1992 (``POSIX.2''). The csh(1) has its own and syntactically different builtin version of time. The utility described here is available as /usr/bin/time to csh users. DIAGNOSTICS
The time utility shall exit with one of the following values: 1-125 An error occurred in the time utility. 126 The utility was found but could not be invoked. 127 The utility could not be found. Otherwise, the exit status of time shall be that of utility. SEE ALSO
csh(1), getrusage(2) FILES
/usr/include/sys/resource.h STANDARDS
The time utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). BUGS
The granularity of seconds on microprocessors is crude and can result in times being reported for CPU usage which are too large by a second. BSD
June 6, 1993 BSD

NAME
time - time a command SYNOPSIS
command utility [argument ...] DESCRIPTION
When a specified command or utility completes execution, prints the elapsed time during the command or utility, the time spent in the sys- tem, and the time spent executing the command or utility. Times are reported in seconds. Execution time can depend on the performance of the memory in which the program is running. The times are printed to standard error. Note that the shell also has a keyword that times an entire pipeline if used anywhere in the pipeline. This action is different than the command which times a particular command if used in a pipeline. Options recognizes the following options: command The command to be executed and timed. Writes the timing statistics to standard error. utility The name of a utility to be invoked and timed. If the utility operand names any of the shell special built-in utilities, the time results are undefined. See csh(1) and ksh(1) for information about special built-in utilities. argument Any string that is an argument to the utility. SEE ALSO
csh(1), ksh(1), sh(1), timex(1), times(2). STANDARDS CONFORMANCE
