>Description:
One of the freebsd-tips in fortune(1) is incorrect on time(1) command.
It says:
To see how long it takes a command to run, type the word "time" before
the command name.
-- Dru <genesis@istar.ca>
In fact that should be "\time" or /usr/bin/time. Builtin time does not
support -h switch.
>How-To-Repeat:
% time -h ping -c 2 host.com
zsh: command not found: -h
-h ping -c 2 host.com 0,00s user 0,01s system 515% cpu
0,002 total
Compare with this:
% \time -h ping -c 2 host.com
PING prioris.mini.pw.edu.pl (IP): 56 data bytes
64 bytes from (IP): icmp_seq=0 ttl=61 time=11.297 ms
64 bytes from (IP): icmp_seq=1 ttl=61 time=9.237 ms
--- host.com ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max/stddev = 9.237/10.267/11.297/1.030 ms
1,01s real 0,00s user 0,00s sys
The tip is missleading.
>Fix:
Change the tip to:
To see how long it takes a command to run, type the word "\time -h" before
the command name.
For example:
% \time -h ping -c 2 host.com
