WordPress development site

I use this script to search and replace the domain name in the WordPress database to adjust a fresh copy from the production site.
Replaces every occurence of ‘www.domainname.tld’ and ‘domainname.tld’ with ‘dev.domainname.tld’.
You then access the development site by adding it to your ‘hosts’ file or internal DNS.

echo File: $1 Replace: $2
cp $1 $1.bak
perl -p -i -e "s|www\.$2|dev\.$2|g" $1
perl -p -i -e "s|://$2|://dev\.$2|g" $1

VirtualBox – convert RAW image to VDI and otherwise

Cloned from: https://blog.sleeplessbeastie.eu/2012/04/29/virtualbox-convert-raw-image-to-vdi-and-otherwise/

VirtualBox – convert RAW image to VDI and otherwise

VirtualBox command-line interface (VBoxManage) provides an easy way to convert raw disk image to the VDI/VMDK format and otherwise.

Let’s assume that we have raw image of the sdb device:

sudo dd if=/dev/sdb of=./sdb.raw

To use it with VirtualBox we need to convert it to the VDI format:

VBoxManage convertdd sdb.raw sdb.vdi --format VDI

To use it with VMware we need to convert it to the VMDK format:

VBoxManage convertdd sdb.raw sdb.vmdk --format VMDK

Convert between VDI/VMDK formats:

VBoxManage clonehd sdb.vdi sdb.vmdk --format VMDK
VBoxManage clonehd sdb.vmdk sdb.vdi --format VDI

Convert to the RAW image:

VBoxManage clonehd sdb.vdi sdb.raw --format RAW

Alternative solution to get back raw image after applying modifications is to use qemu-img command from qemu package:

qemu-img convert -f vmdk sdb.vmdk -O raw sdb.raw

Now we can write image to the device:

sudo dd if=./sdb.raw of=/dev/sdb
