Try just time instead of timethis.

Although be aware that there's often a shell builtin version of time and a binary version, which will give different results:

$ time wget -q -O /dev/null http://unix.stackexchange.com/

real    0m0.178s
user    0m0.003s
sys     0m0.005s

vs

$ \time wget -q -O /dev/null http://unix.stackexchange.com/
0.00user 0.00system 0:00.17elapsed 4%CPU (0avgtext+0avgdata 0maxresident)k

By using the executable time instead of the shell builtin, you can specify the output format and values. E.g. get the real elapsed time together with the command name and parameters

/usr/bin/time --format='%C took %e seconds' sleep 3
sleep 3 took 3.00 seconds

Note that you must specify the path for time, else you will default to using the shell built-in.

notice that: the path is important. Don't just use 'time' in bash. Instead, use /usr/bin/time –  CodeFarmer Aug 31 at 5:06
