ExecutionPolicy script is not recognized as an internal or external command

Fix : Run the command from PowerShell! (PowerShell as Administrator )

If above solution does not work - try this

Dont work for me: and in cmd, and powershell, in all cases script was runned with admin permission, but I get the same error.
I`m also try to run it from npm folder where its located.

PS C:\Users\mishelen\AppData\Roaming\npm> npm-windows-upgrade
npm-windows-upgrade 0.5.1
? This tool will upgrade npm. Do you want to continue? Yes
Scripts cannot be executed on this system.
To fix, run the command below as Administrator in PowerShell and try again:
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force

Refer: https://github.com/felixrieseberg/npm-windows-upgrade/issues/35

Not able to connect ssh - for AWS server - (error). - keypair.perm permission deny OR keypair.pem does not exist?

Solution to below issue ( in Mac)

Could not find /Users/keypairs/key-pair.pem

Connecting to: server at IP 90.xx.x.xxx with keypair key-pair

Warning: Identity file /Users/key-pair.pem not accessible: No such file or directory.

ec2-user@90.xx.x.xxx : Permission denied (publickey).

Try this :

1. In terminal - Go to the path where the "key-pair.pem" is sitting.

2. Check the permissions - just why typing the command -

c:/Users/keypairs> ls -la

3. Run the command -

c:/Users/keypairs> chmod 400

or c:/Users/keypairs> chmod 600

This should resolve the issue-- At least this worked for me!

Check a String Contains a Substring in JavaScript

Options : Use the `indexOf()` Method

The simplest and fastest way to check whether a string contains a substring or not in JavaScript is the indexOf() method. This method returns the index or position of the first occurrence of substring within the string, otherwise, it returns -1 if no match found. Here is an example:

```
<script>
```
```
    // Sample string
```

    var str = "The quick brown fox jumps over the lazy dog."

```
    
```

    // Check if the substring exists inside the string

```
    var index = str.indexOf("fox");    
```
```
    if(index !== -1){
```
```
        alert("Substring found!");
```
```
    } else{
```
```
        alert("Substring not found!");
```
```
    }
```
```
</script>
```

In ES6 you can use the includes() method to check if a contains a substring. This method simply returns true or false instead of the index. Let's check out an example:

```
<script>
```
```
    // Sample string
```

    var str = "The quick brown fox jumps over the lazy dog."

```
    
```

    // Check if string contains substring

```
    if(str.includes("fox")){
```
```
        alert("Substring found!");
```
```
    } else{
```
```
        alert("Substring not found!");
```
```
    }
```
```
</script>
```

Check out the tutorial on JavaScript ES6 features to learn about new features introduced in ES6.

Further, you can use the search() method to search a particular piece of text or pattern (using regular expression) inside a string. Like indexOf() method the search() method also returns the index of the first match, and returns -1 if no matches were found.

```
<script>
```
```
    // Sample string
```

    var str = "Color red looks brighter than color blue."

```
    
```
```
    // Search the string for a match
```
```
    var index = str.search(/color/i);  
```
```
    if(index !== -1){
```
```
        alert("Substring found!");
```
```
    } else{
```
```
        alert("Substring not found!");
```
```
    }
```
```
</script>
```
