Failed To Install syslinux on USBDRIVE with Mac OS X

I am creating Ubuntu Server 13.10 Bootable USBDRIVE with command line using Mac OS X, In this i tried to install Syslinux on USBDRIVE by using syslinux command by following:

xxx-Mac:~xxx$ sudo syslinux /dev/disk2s1

here i am using disk2s1 for my usbdrive but i got following error:

-bash: syslinux: command not found

What is alternative to install syslinux on usbdrive, Mac OS X dont include any syslinux command?

No there isn't syslinux on Mac OS X. You will have to install it first as described on this blog: Creating a bootable USB stick from OSX

The essentials steps will be based on:

• Disk Utility,
• Syslinux
• UNetbootin

The second explains the few basic steps to get and install Syslinux.
