What's Batch files?
A batch (or BAT) file represents a script file that stores a series of commands set to be executed in a serial
order. Such files are often used to load programs, run several simultaneous processes, or automate
repetitive tasks. Contrary to popular belief, creating BAT files doesn’t require advanced computer skills.
Some basic commands of batch file:
1. ECHO – Prints out the input string. It can be ON or OFF, for ECHO to turn the echoing feature on
or off. If ECHO is ON, the command prompt will display the command it is executing.
2. CLS – Clears the command prompt screen.
3. TITLE – Changes the title text displayed on top of prompt window.
4. EXIT – To exit the Command Prompt.
5. PAUSE – Used to stop the execution of a Windows batch file.
6. :: / REM – Add a comment in the batch file.
7. COPY – Copy a file or files.
Examples:
“@ECHO OFF
ECHO Hello and welcome to batch scripting! If you’re seeing this text, it means you’ve
successfully created a BAT file in Windows. Great job!
PAUSE”.
“@ECHO OFF
move Source-Path*.* Destination-Path”.
“ECHO OFF
copy [source] [destination]”.
“@ECHO OFF
DEL [file destination and name]”.
@ECHO OFF
REM This is a comment line.
REM Listing all the files in the directory Program files
DIR"C:\Program Files" > C:\geeks_list.txt
ECHO "Done!"
Homework:
