Export VirtualBox VM with PowerShell and show progress



I want to export all my VirtualBox VMs for backup purpose using an automated script. The following command should do the export in my PS script:


cmd.exe -c "vboxmanage export Antergos -o D:Temptest.ova"



By running the vboxmanage command in PowerShell, It shows me the progress in 10% steps like this:


vboxmanage


PS C:UsersXYZ> vboxmanage export Antergos -o D:Temptest.ova
0%...10%...



But using the cmd call like above I don't get any output. It would be great to have some progress, since some VMs are quite big (~70GB). I tried different variations:


cmd


iex 'vboxmanage export "$($name)" -o "$targetFile"'
& "vboxmanage export ""$($name)"" -o ""$targetFile"""
Invoke-Command -ScriptBlock cmd.exe /c "vboxmanage export ""$name"" -o ""$fullTargetFile""" 4>&1 4>&1
Invoke-Expression "vboxmanage export ""$name"" -o ""$fullTargetFile"" 2>&1"



None of them show me the progress, which seems wired to me since e.g. Invoke-Expression "vboxmanage --help" print the help, but no progress when using vboxmanage export live above.


Invoke-Expression "vboxmanage --help"


vboxmanage export

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
