PowerShell: Equivalent to UNIX find/grep

Product: Windows PowerShell

I was trying to find out the PowerShell command that equivalent to following UNIX command to search through all files for a particular text (or regular expression)

find . | grep -i "family_picture"

The PowerShell equivalent is

Get-ChildItem -recurse | select-string -pattern "family_picture"

Default is not case sensitive, so no need to map "grep -i" parameter. If needed case sensitive, then it will be

Get-ChildItem -recurse | select-string -pattern "family_picture" -casesensitive

Merge AVHDX Hyper-V Checkpoints

When you create a snapshot of a virtual machine in Microsoft Hyper-V, a new file is created with the .avhdx file extension. The name of the file begins with the name of its parent VHDX file, but it also has a GUID following that, uniquely representing that checkpoint (sometimes called snapshots). You can see an example of this in the Windows Explorer screenshot below. Creating lots of snapshots will result in many .avhdx files, which can quickly become unmanageable. Consequently, you might want to merge these files together. If you want to merge the .avhdx file with its parent .vhdx file, it’s quite easy to accomplish. PowerShell Method Windows 10 includes support for a Merge-VHD PowerShell command, which is incredibly easy to use. In fact, you don’t even need to be running PowerShell “as Administrator” in order to merge VHDX files that you have access to. All you need to do is call Merge-VHD with the -Path parameter, pointing to the .avhdx file, and the -Des

Openstack manila phần 4: Native GlusterFS Driver

Tiếp tục loạt bài về Openstack Manila hôm nay tôi sẽ cấu hình backend sử dụng GlusterFS Yêu cầu phiên bản GlusterFS >= 3.6. Với glusterfs nếu cluster của bạn không hỗ trợ snapshot thì trên manila cũng sẽ mất đi tính năng này. Để cấu hình snapshot ta sẽ cấu hình Thin Provision theo bài hướng dẫn link Với bài lab của mình có 2 node và chạy kiểu replicate. Mình sẽ tạo các thinly provisioned và tạo volume trên đó.

Zabbix, AWS and Auto Registration

One of the things I love the most with AWS is auto-scaling . You choose an AMI, set some parameters and AWS will spin instances up and down whenever a threshold is breached. But with all these instances spinning up and down there are some unknowns. For example, what is the IP address of the new instance? Its host name? This can be critical when other components of your infrastructure are dependent on knowing these parameters. I had this problem when I started to use Zabbix as the monitoring system. At first it seemed like a complicated one, but Zabbix has a wonderful feature called Auto Registration which can be used exactly for this situation. I will try to show how to configure auto registration both on the client (EC2 instance running Ubuntu 14.04) and on the Zabbix server (Zabbix Server 2.4.2). Zabbix-agent Installation and Configuration Let’s start with installing zabbix-agent on the Ubuntu client: 1 2 $ sudo apt-get update $ sudo apt-get install -y zab
