#!/bin/bash



pvcreate /dev/md5 && echo "pvcreate succeeded" || echo "pvcreate failed"



vgcreate vg0 /dev/md5 && echo "vgcreate succeeded" || echo "vgcreate failed"



lvcreate -L 200MB vg0 -n test && echo "lvcreate succeeded" || echo "lvcreate failed"

Logical AND && part will be executed only if the command succeeded(true) else Logical OR || (false) part will be executed.
