The command might be called ab2 or then you don't have Apache Benchmark installed at all. I don't currently have my Mind Reader Expansion Pack docked to my head so you need to rephrase your question quite a bit. – Janne Pikkarainen Jul 28 '11 at 10:42
As @Janne said you should rephrase your question to include more details. Which Linux Distribution are you using, which version of it? Did you compile Apache yourself or did you use a binary distribution for your system ? – pacey Jul 28 '11 at 11:10
My guess is the OP is trying to run that command from his workstation (which may not be Linux, or may not have Apache installed) to test a website hosted somewhere else (which is the best way to do it). – EightBitTony Jul 28 '11 at 11:34
If you are using ubuntu then you can follow this link: [… [1]:… – kamal Oct 1 '11 at 17:09

You run ab from a machine / account which has it installed. It's usually part of the Apache2 package in various Linux distributions, or you can download / compile it yourself. You don't tell us anything about your setup though so it's not possible to answer in more detail.
