How to display a simple list of all disks like this dev sda dev sdb

Question

I am trying to run these Linux commands and wanted to get a simple list of all disks, which is like this  /dev/sda /dev/sdb ?

Can someone tell me how to get it?

Thanks

You can list all the disk in system by following way. Lets have a look,

ls : Show Individual partitions.

# ls /dev/sd* /dev/sda /dev/sda1

ls: just disks, ignore partitions

# ls /dev/sd*[a-z]
/dev/sda

fdisk : 

# fdisk -l 2>/dev/null |awk '/^Disk \//{print substr($2,0,length($2)-1)}'
/dev/xvda

These are ways where you will get a list of disk present in your system.
