Command Line

Sometimes referred to as a command script, a command language is a language used for executing a series of commands that would otherwise be executed at the prompt. A good example of a command language is Microsoft Windows batch files. Although command languages are useful for executing a series of commands, their functionality is limited to what is available at the command line which can make them easier to learn.

Learn to Code

The Learn to Code movement has picked up momentum worldwide and that is actually a good thing as even basic programming skills can have a major impact. If you can teach yourself how to write code, you gain a competitive edge over your peers, you can think more algorithmically and thus can tackle problems more efficiently.
Lena Groeger: When I started learning to code, I was amazed by how much was out there: introductory videos, explanatory blog posts, tips and tricks and step-by-step guides. If you're a journalist who wants to make a news app or a student interested in learning to code, you have plenty of paths to choose from.

Multiple Codes

A Chrome-specific bookmarklet that extracts SVG nodes and accompanying styles from an HTML document and downloads them as an SVG file—A file which you could open and edit in Adobe Illustrator, for instance. Because SVGs are resolution independent, it’s great for when you want to use web technologies to create documents that are meant to be printed (like, maybe on newsprint). It was created with d3.js in mind, but it should work fine no matter how you choose to generate your SVG.

Regular Expressions

Moved content to Data Analysis.

Rename Files & Folders

Rename Files Using REN or RENAME
- RENAME [drive:][path]filename1 filename2
- REN [drive:][path]filename1 filename2
Rename Folders: You can rename folders with the MOVE command:
- MOVE d:\path\folder1 folder2
To rename files in bulk more efficiently, you can either learn some complex shell scripting language (SED, AWK, Perl) or switch to something more simple--a spreadsheet.

Bulk Rename Files

Rename List of Files With Batch File

It's easy to rename a group of files by running a batch file (file.bat), configured something like this:

rename "Old-File_001.jpg" "New-File_001.jpg"
rename "Old-File_002.jpg" "New-File_002.jpg"
rename "Old-File_003.jpg" "New-File_003.jpg"
  1. Using a simple text editor (such as Notepad++), just create your batch file using the format shown above.
  2. Save the file as rename.bat (or similar name) in the same folder containing the files you want to rename.
  3. Double-click your batch file (e.g. rename.bat) to rename the files to the new file name.

Rename List of Folders With Batch File | Include Full Paths

It's easy to rename a group of folders located in different parent directories by running a batch file (file.bat), configured something like this:

MOVE "C:\Parent Directory One \Sub Directory\Old Folder Name" "C:\Parent Directory One \Sub Directory\New Folder Name"
MOVE "C:\Parent Directory Two \Sub Directory\Old Folder Name" "C:\Parent Directory Two \Sub Directory\New Folder Name"
MOVE "C:\Parent Directory Three \Sub Directory\Old Folder Name" "C:\Parent Directory Three \Sub Directory\New Folder Name"
A batch file contains a series of DOS commands, and is commonly written to automate frequently performed tasks. Instead of typing the same commands over and over, you can simply double-click the batch file. Writing a batch file is easier than it looks; the difficult part is making sure that everything happens in the right order. Well-made batch files can save you a lot of time over the long run, especially if you deal in repetitive tasks.
