time - time a command
Syntax
time command
/bin/time command
Description
The command lets the specified command execute and then outputs the amount of elapsed real time, the time spent in the operating system,
and the time spent in execution of the command. Times are reported in seconds and are written to standard error.
If you are using any shell except the C shell, you can give the command as shown on the first line of the Syntax section. If you are using
the C shell, you must use the command's full pathname as shown on the second line of the Syntax section. If you do not use the full path-
name, will execute its own built-in command that supplies additional information and uses a different output format.
The command can be used to cause a command to be timed no matter how much CPU time it takes. For example:
% /bin/time cp /etc/rc /usr/bill/rc
0.1 real 0.0 user 0.0 sys
% /bin/time nroff sample1 > sample1.nroff
3.6 real 2.4 user 1.2 sys
This example indicates that the command used negligible amounts of user and system time and had an elapsed time of 1/10 second (0.1). The
command used 2.4 seconds of user time and 1.2 seconds of system time, and required 3.6 seconds of elapsed time.
Restrictions
Times are measured to an accuracy of 1/10 second. Thus, the sum of the user and system times can be larger than the elapsed time.
