Declaring Variable Rule

• Variable can contain a combination of letters, digits, underscores ( _ ), and
• dollar signs ( $ ).
• Must begin with a letter A-Z or a-z or underscore or dollar sign
• A variable name cannot start with a number
• Must not contain any space characters
• JavaScript is case-sensitive
• Can‟t use reserved keywords

Declaring Variable

A variable declared without a value will have the value undefined

<script type="text/javascript">
	document.write("Hello DevOpSchool");  
</script>

<script src="devops.js" type="text/javascript"></script>

<script> – Opening Script Tag.

src – It’s an attribute of the script.

name.js – This is our script file, which we created. The code of javascript is written inside devops.js.
In which DevOps is the file name, .js is the extension. Javascript has an extension of .js

Type – This is also an attribute of the script tag, it tells the browser that it is javascript. Now it is not necessary to write it, you can leave it if you want.

Text/javascript – It defines what type these documents are.

document.write(“Hello World”); – This is a function which is displaying the data.

</script> – Closing Script tag.

How to link more than one External?

You can link more than one JavaScript file to a single document. Just need to write different script tags for that.

<script src="devops1.js" type="text/javascript"></script>
<script src="devops2.js" type="text/javascript"></script>
<script src="devops2.js" type="text/javascript"></script>
<script src="devops3.js" type="text/javascript"></script>

How to use inline and External together in javascript?

No, both cannot be written together. But both inline and external can be written separately.

<!DOCTYPR>
<HTML>
    <head><title></title>
        
            
        </script>
    </head>
    <body>
        <h1>I am Heading</h1>
        <p>I am Paragharph</p>
        
        <script type="text/javascript">
			document.write("Hello Vijay");  
		</script>
        <br>
        
        <script src="devops.js" type="text/javascript"></script>
        
    </body>
</html>

Write funtion

This function is used to write arbitrary HTML and content into the page. If we use this function after an HTML document is fully loaded, will delete all existing HTML. It is used only for testing purposes.

Ex:-    document.write("Hello world");
	    document.write(variable);
	    document.write(4+2);
	    document.write("hello world . <br>");
	    document.write("hello world . <br>" + variable +"<br>");

Alert function in JavaScript

The data that will be displayed in it will be in the dialog box. You forcefully want to see this thing, then only this work will be done. In that case, you use a window. alert

Ex:- window.alert("Hello World");
	 window.alert(variable);
	 window.alert(4+2);
	 window.alert("hello world"+ variable);

<html>
	<head><title>Hello JS</title>
		<script>
			window.alert("Hello");
		</script>
	</head>
	</body>
`		<h1>I am heading</h1>
		<p>I am Paraghraph</p>
		
		<script src="name.js" type="text/javascript">
		</script>
	</body>
</html>

Identifier

An identifier is a name having a few letters, numbers, and special characters _(underscore). It is used to identify a variable, function, symbolic constants, and so on.

Ex:- X2
PI
Sigma
Matadd

Veriable in JavaScript

Variable can be any name, in which a combination of letters, numbers, and special characters can be written _()(underscore) and $(dollar). It is not necessary that there should be only a combination, it can only be a letter.

Ex:- c, fact, b33, total_amount ect.

Rules of Veriable in JavaScript

• Variable can contain a combination of letters, digits, _()(underscore), and dollar signs($).
• Must begin with a letter A-Z or a-z or underscore or dollar sign.
• A variable name cannot start a number.
• Must not contain any space characters.
• JavaScript is case-sensitive
• Can’t use reserved keywords.

A Jenkins Admin can execute groovy scripts remotely by sending an HTTP POST request to /script/ url or /scriptText/.

curl example via bash

curl -d "script=<your_script_here>" https://jenkins/script
# or to get output as a plain text result (no HTML)
curl -d "script=<your_script_here>" https://jenkins/scriptText

curl submitting groovy file via bash

curl --data-urlencode "script=$(< ./somescript.groovy)" https://jenkins/scriptText

curl submitting groovy file providing username and password via bash

curl --user 'username:password' --data-urlencode "script=$(< ./somescript.groovy)" https://jenkins/scriptText

Jenkins CLI offers the possibility to execute groovy scripts remotely using groovy command or execute groovy interactivelly via groovysh.

i have write
“Develop a function that accepts a string of names separated by comma (example given below), add those names in an array and display the names added in the array”

Example: rajani; Disha; Dhara; Hunny ;moon
without using split function
can i use mid function

i am able to display name but with comma
Dim fruits()
ReDim fruits(100)
nofruits=0
‘we do not know how many fruit names we are going to enter and so, we have declared the array size as 100
For i=0 to 100

If ans=vbNo Then
Exit For

nofruits=nofruits+1
Next
ReDim Preserve fruits(nofruits)
‘Redim keyword resets the number of elements that can be accommodated in the array.

For each fruit in fruits
‘Using For Each Next we have displayed all the names of the fruits which was entered and kept in fruits array.

The easy way to do it is to note that a Java properties file has the same format as a basic shell script.

However, there’s a trick to it. If you just run the properties file like so:

sh appl.properties

The assignments will be made at the sub-level, then discarded when the properties file (script) ends execution.

So to get the properties in a calling script, you need to use the “source” command:

. appl.properties

Note that the space after the initial dot is very important!

To reference shell variable assignments, you use the “$” to indicate variable substitution.

So, to put it all together:

# #!/bin/sh
# # Sample shell script to read and act on properties
#
# # source the properties:
# . appl.properties
#
# # Then reference then:
# echo "My name is $name and I'm $age years old."

If you have developed a script using the Korn shell, how will you make sure the script will use that shell even if login shell is different?

renjith replied the topic: Re: Make sure script is running using korn shell

begin shell script with Shabang/interpreter line

#!/bin/ksh

rajeshkumar replied the topic: Re: Make sure script is running using korn shell

There are 2 ways to run a script with specific shell no matter if login shell is different..

Method 1:
Use following before any shell script…
#!/bin/ksh

Method 2:

Execute shell script with ksh

rajeshkumar replied the topic: Re: Run php script using cronjob / crontab
If your PHP scripts do have executable permissions like 755 or -rwxr-xr-x and they have one of the PHP filename extensions above, then you do not need to specify the php interpreter in the command portion of your cron line, like this:

5 17 * * 2 /myscript.php

The above cron would run myscript.php in your home directory every Tuesday at 5:05PM.

some more example…

28 14 * * * /usr/local/bin/php -q /myscript.phtml
6 3 20 4 * /usr/local/bin/php -q /htdocs/www/x.php
