typo in multipath device handler setup

In the "note" section on:

https://help.ubuntu.com/12.04/serverguide/multipath-dm-multipath-config-file.html

"""
Whenever a hardware_handler is specified, it is your responsibility to ensure that the appropriate kernel module is loaded to support the specified interface. These modules can be found in /lib/modules/`uname -r`/kernel/drivers/scsi/device_handler/ . The requisite module should be integrated into the initrd to ensure the necessary discovery and failover-failback capacity is available during boot time. Example,

# cat scsi_dh_alua >> /etc/initramfs-tools/modules ## append module to file
# update-initramfs -u -k all
"""

That "cat" command is wrong, it should have been "echo". Thankfully no harm is done in it's current
form, no good is done either.
