NAME

6       time - time a command
7

SYNOPSIS

9       time command
10

DESCRIPTION

12       The  given  command  is executed; after it is complete, time prints the
13       elapsed time during the command, the time spent in the system, and  the
14       time spent in execution of the command.  Times are reported in seconds.
15
16       On  a  PDP-11, the execution time can depend on what kind of memory the
17       program happens to land in; the user time in MOS is often half what  it
18       is in core.
19
20       The times are printed on the diagnostic output stream.
21
22       Time is built in to csh(1), using a different output format.
23

BUGS

25       Elapsed  time  is  accurate to the second, while the CPU times are mea‐
26       sured to the 100th second.  Thus the sum of the CPU times can be up  to
27       a second larger than the elapsed time.
28
29       Time  is  a  built-in  command to csh(1), with a much different syntax.
30       This command is available as ``/bin/time'' to csh users.
