Determine the execution time of a command (UNIX)
time command
Neutrino
- command
- The command, including any of its options, for which the execution time
is to be determined.
The time utility and the time shell built-in
determine the execution time of command, which must be specified.
When execution of command is complete, the time utility
displays the total elapsed time for execution, the time spent in the system,
and the time spent in executing command. Times are
reported in hours, minutes, and seconds.
Times aren't always accurate to the milliseconds as displayed, depending
on the tick size.
Time the execution of dcheck -b2048 /dev/hd0:
time dcheck -b2048 /dev/hd0
The time utility exits with the exit status of the
command that was timed.
The time command doesn't obtain execution information
from a remote node. To time remote programs, use the
on
command to run time
on the same machine as the program being timed, e.g.:
on -n 61 time sleep 30
NOT:
time on -n 61 sleep 30
