Read is a mobile application that allows users to read and share news articles, with no ads or banners. It also has an integrated cryptocurrency wallet so users can earn rewards for reading the material they consume. The app’s creators say it will be more lucrative than a typical job in the future due to these features, as well as its decentralized nature which means Read won’t have advertising like other apps do today.
The “read past tense” is a verb that means to read something that happened in the past.
You may interactively prompt the script user for input with the Read-Host PowerShell cmdlet. Let’s look at some real-world examples of how the Read-Host PowerShell cmdlet may be used.
With Read-Host, you may prompt for input.
In a PowerShell script, the Read-Host cmdlet does two tasks: it stops execution and accepts input. That is all there is to it. Read-Host is a basic cmdlet that comes in handy when you require information from the script user.
The Read-Host cmdlet’s most fundamental requirement is that the Prompt argument be used. You may use the Prompt option to provide the script user some guidance on what to type. If your script needs a server name, for example, you might use Read-Host to ask the user for it when the script runs.
As you can see below, when you run Read-Host from inside the PowerShell console with the Prompt option, PowerShell stops all execution and shows my prompt message, which explains what we’re looking for.
PowerShell prompt for Read-Host
Let’s make a script out of this. Read-Host returns information to your code whenever a user enters information at the prompt. By assigning the output to a variable, you can simply capture this information. I’m thinking about asking for a server name and then doing stuff with it. Otherwise, I’d want to provide a warning to the user, informing them that I absolutely must have that server name.
$serverName = Read-Host -Prompt ‘Server name to process’ if $serverName = Read-Host -Prompt ‘Server name to process’ if $serverName = Read-H Write-Host ($serverName) “Now we may utilize the server name [$serverName] in our code” else “No server name input,” Write-Warning -Message
I can then ensure that my user enters a server name using a simple if/then construct. I can then capture it and do anything with it, or send a warning message, if they don’t.
When there is no input, a warning appears.
Requesting Passwords
You should be aware that storing passwords in plain text in your scripts is not a smart idea. Passwords saved in plain text in RAM are also never a smart idea. PowerShell offers a notion called a secure string, which is a basic string that is encrypted, to get around this.
A secure string may include any kind of sensitive data; a password is an excellent example. What does this mean in terms of Read-Host? The AsSecureString option of the Read-Host cmdlet enables you to not only save the output as a secure string, but also display an asterisk while typing to disguise your secret from prying eyes!
Consider the following scenario: I have a deep, dark secret that I don’t want anybody to know about, but I need to provide this password to some form of program. You can see below that you’re on to me when I don’t utilize AsSecureString! When I use AsSecureString, however, every character I input is replaced with an asterisk, and the result is stored as a secure string rather than a plain-text string, which protects my secret.
With Read-Host, you may accept secure input.
