NAME

time − time a command

SYNOPSIS

time command

DESCRIPTION

The command is executed; after it is complete, time prints the elapsed time during the command, the time spent in the system, and the time spent in execution of the command.  Times are reported in seconds. 

The execution time can depend on the performance of the memory in which the program is running. 

The times are printed on standard error. 

HARDWARE DEPENDENCIES

Series 500:
For those computers with multiple CPU’s, the child CPU times listed may be greater than the actual real elapsed time, since CPU time is counted on a per-CPU basis.  Thus, if three CPUs are executing, the times listed are obtained by adding the execution times of each CPU.

SEE ALSO

times command in sh(1), timex(1), times(2). 

INTERNATIONAL SUPPORT

8- and 16-bit data, 8-bit filenames.
