Windows 10 powershell’s Linux sudo apt-get install like CMDlet with Chocolately app

The Story

Windows 10 has arrived finally and with it came lot of new features, and one of my favorite new features is that you can finally install applications through powershell just like Linux OS’s terminal window command (apt-get install).

Although the command is still pretty new and lack many repositories where you can find and install applications from.

There’s already some people who are working on adding sources of applications which you can test initially before Microsoft asks product companies to start making their own repositories so Powershell can trust these sites and applications.

One of the sites that are working on providing Windows 10 with repositories is https://chocolatey.org/ which provides hundreds of softwares that can be installed through PS.

To install Chocolately repository simply do the following

Open powershell as an administrator and paste the following cmdlet

@powershell -NoProfile -ExecutionPolicy Bypass -Command “iex ((new-object net.webclient).DownloadString(‘https://chocolatey.org/install.ps1’))” && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Then this

iex ((new-object net.webclient).DownloadString(‘https://chocolatey.org/install.ps1’))

clip_image002

From

https://chocolatey.org/

As soon as you have installed chocolately, you will get a new huge list of applications that can be installed with a very simple and short cmdlet as in the below screenshots.

The good things about these cmdlets is it can be used to deploy an app for a huge number of clients by simply running the script through GPO or batch file.

I am going to install VLC and Google drive on my computer using these cmdlet …

Find-Package

Find-package -Name VLC

If an application doesn’t install, how to troubleshoot it?

If for instance you were trying to install a package or app and that doesn’t work or get stuck then you can navigate to the Chocolately directory and delete any package that you tried to install but were suspended for any reason.

c:\Chocolately\lib\

clip_image012

You can simply delete the whole directory or the file that ends with extension .nupkg and try again to install…

CHANGE WORDPRESS DOMAIN USING HTTP://WP-CLI.ORG/

These are instructions that demonstrate how to change WordPress to match your replaced or changed Public domain. as this occurs in case if you are already using WordPress and have it published on let’s say Domain1.com and then you transferred this domain to Domain2.com.

When you try to reach wordpress website from your new public domain. you might not reach it or wordpress might try to redirect you to your old domain1.com instead.

In order to fix this, we’ll have to use a tool called wp-cli which fixes this configuration problem. to do so please open your SSH shell or get in your UBuntu server and do the following.

  1. sudo curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
clip_image001

2. From User@UbuntuServer:/var/www/html$ I will run the following command to make sure that the command is working

sudo php wp-cli.phar –info

clip_image002

3. I’ll move the file to a new path and location so I can access it from anywhere using only the command WP.

First I will give the required permissions

moh10ly@Ubunut-Mohammed:/var/www/html$ sudo chmod +x wp-cli.phar

clip_image003

Next I will move the file

sudo mv wp-cli.phar /usr//local/bin/wp

clip_image004

3. Check if the file is working properly after moving?

clip_image005

4. Final step is to change the domain of your wordpress site to a new domain.

My previous domain was www.mytechweb.ga and now I changed it to www.moh10ly.website

So I only used two commands to change the domain name to the new on

5. moh10ly@Ubunut-Mohammed:/var/www/html$ wp option update home “http://www.moh10ly.website

clip_image006

6. moh10ly@Ubunut-Mohammed:/var/www/html$ wp option update siteurl “http://www.moh10ly.website

clip_image007

Now I tested my website and it’s working perfectly…

5- OneDrive for Linux.

http://xmodulo.com/sync-microsoft-onedrive-linux.html

Install onedrive-d on Linux

While onedrive-d was originally developed for Ubuntu/Debian, it now supports CentOS/Fedora/RHEL as well.

Installation is as easy as typing the following.

$ git clone https://github.com/xybu92/onedrive-d.git

$ cd onedrive-d

$ ./inst install

First-Time Configuration

After installation, you need to go through one-time configuration which involves granting onedrive-d read/write access to your OneDrive account.

First, create a local folder which will be used to sync against a remote OneDrive account.

$ mkdir ~/onedrive

Then run the following command to start the first-time configuration.

$ onedrive-d

It will pop up a onedrive-d’s Settings window as shown below. In “Location” option, choose the local folder you created earlier. In “Authentication” option, you will see “You have not authenticated OneDrive-d yet” message. Now click on “Connect to OneDrive.com” box.

clip_image008

It will pop up a new window asking you to sign in to OneDrive.com.

clip_image009

After logging in to OneDrive.com, you will be asked to grant access to onedrive-d. Choose “Yes”.

clip_image010

Coming back to the Settings window, you will see that the previous status has changed to “You have connected to OneDrive.com”. Click on “OK” to finish.

Sync a Local Folder with OneDrive

There are two ways to sync a local folder with your OneDrive storage by using onedrive-d.

One way is to sync with OneDrive manually from the command line. That is, whenever you want to sync a local folder against your OneDrive account, simply run:

$ onedrive-d

onedrive-d will then scan the content of both a local folder and a OneDrive account, and make the two in sync. This means either uploading newly added files in a local folder, or downloading newly found files from a remote OneDrive account. If you remove any file from a local folder, the corresponding file will automatically be deleted from a OneDrive account after sync. The same thing will happen in the reverse direction as well.

Once sync is completed, you can kill the foreground-running onedrive-d process by pressing Ctrl+C.

clip_image012

Another way is to run onedrive-d as an always-on daemon which launches automatically upon start. In that case, the background daemon will monitor both the local folder and OneDrive account, to keep them in sync. For that, simply add onedrive-d to the auto-start program list of your desktop.

When onedrive-d daemon is running in the background, you will see OneDrive icon in the desktop status bar as shown below. Whenever sync update is triggered, you will see a desktop notification.

6- Evolution Email Client for Exchange accounts.

If you ever thought of using an e-mail client that supports your account on Microsoft Exchange Email server’s protocol which is known as (RPC over HTTP) then you have probably used Mozilla thunderbird or kmail, geary..etc but all those clients don’t support Exchange’s most flexible connectivity which is RPC over HTTP that will sync all your emails, contacts, tasks, calendars ..etc

To Install evolution, all you have to do is open Linux Terminal and type the following

Sudo apt-get install evolution

clip_image014

Since I already have Evolution installed it won’t proceed and will tell me that it’s already installed. but that’s not all!

In order to setup an Exchange account on Evolution you will have to install an Evolution plugin that will support the web services for the RPC over http connectivity which is known as (EWS = Exchange Web Services).

In order to install this plugin you will have to type the following command

Sudo apt-get install Evolution-ews

clip_image015

Once you install the plugin, you can launch the program and setup your account as following.

Click on Add as in the picture

clip_image016

When you click add you should be welcomed by a message saying “Welcome to Evolution wizard ..etd”

Click Continue and then type in your name and email address in the next window

You can skip the automatic configuration as Evolution still doesn’t support Exchange Autodiscover mechanism for auto configuration of the account. so you must manually provide all the configuration of your exchange as following

clip_image017

In the host URL you will have to provide your Exchange server’s EWS URL which usually looks like this

https://mail.domain.com/ews/exchange.asmx

In my case I am using an Office 365 account so instead I’ll use Microsoft’s EWS url.

https://outlook.office365.com/ews/exchange.asmx

For the OAB (Offline Address Book) you also need to provide the configured URL of the OAB on your Exchange Server. which in my case again it’s Microsoft Office 365.

https://outlook.office365.com/OAB

you will need to make sure that the correct authentication method is set (NTLM) in my case, this can vary though on Exchange server’s Outlook Anywhere configuration. it can be Basic as well. so it’s up to your configuration to choose but for Office 365 it’s NTLM.

clip_image018

Once you finish the configuration you can continue and you’ll get prompted to enter your Credentials. as soon as you finish typing your Password hit enter and your e-mails will start syncing. as in the following snapshot

clip_image019

That’s it, you’re setup here either if it’s an exchange on-premises or Office 365 for Linux desktop client.

Here’s another guide for the new mapi connectivity for Evolution, probably the same steps

7- For Office (Word, Powerpoint ..etc) I prefer to use Kingsoft’s community version along with LibreOffice

Since Libre office provide more tools or the full package I still use it on Linux but Kingsoft’s WPS tools have a user friendly and rich of tools GUI.

clip_image020

In order to download WPS software you will have to navigate to the link below and download the suitable version with your Linux OS. or use the terminal to download latest available version with the following command

sudo apt-get install wps-office

http://wps-community.org/download.html

8- For media there are various available software and tools that you can use on Linux to either listen to music or edit mp3s or convert media types.

A- Audacity (Convert and Edit audio files).

B- Spotify (listen to music online)

C- Clementine (Listen to Music on your computer)

D- VLC (Watch Videos on your PC) or use it as a streaming server.

There are other useful tools and things to do on Linux OS as it’s a very flexible and customizable OS but I’ll end this article here and write a new one about how to decorate your welcome screen and your desktop with beautiful pictures and tools.

Hope you find this useful
