How to run lmbench on Ubuntu

[mahesh]

I already run apt-get install lmbench lmbench-run lmbench-doc, When I type in lmbench, the command still not found.

lqs@lqsmachine:~$ lmbench
lmbench: command not found


Also, When I type sudo lmbench-run, it shows me:

lqs@lqsmachine:~$ sudo lmbench-run
/usr/bin/lmbench-run: 1: /var/lib/lmbench/config: Permission denied
No config file?
Benchmark run finished....
Remember you can find the results of the benchmark
under /var/lib/lmbench/results

I wanna know how to use lmbench in Ubuntu.
