Hi there,
STOP!
I see you don't get the whole point. This is not the only one error in
fortune tips given by Dru*.
Consider that:
1.
alphax# time ping -c prioris.mini.pw.edu.pl

These examples are from:
alphax# uname -a

Jun 16 20:46:55 CEST 2003 root@alphax.mini.pw.edu.pl:/usr/obj/usr/src/sys/
The shell is csh. From zsh it looks much different:
alphax# time ping -c 2 prioris.mini.pw.edu.pl
PING prioris.mini.pw.edu.pl (194.29.178.2): 56 data bytes
64 bytes from 194.29.178.2: icmp_seq=0 ttl=68 time=0.666 ms

ping -c 2 prioris.mini.pw.edu.pl 0.00s user 0.01s system 0% cpu 1.012
total
If someone has csh as his/her default shell the output is totally
unreadable. This is because you call shells builtin. Prefixing time
command with a "\" you prevent such errors as then you call time(1).
I guess you did not perform any tests before closing the PR.
Have a good one,
greg
