The PAUSE Command: Freezing Time
Say you create a batch file which shows the Directory Listing of a particular folder(DIR) before performing some other task. Or sometimes before deleting all files of a folder, you need to give the user time to react and change his mind. PAUSE, the name says it all, it is used to time out actions of a script.Consider the following scenario:
REM This Batch program deletes *.doc files in the current folder.
REM But it gives the user to react and abort this process.
ECHO WARNING: Going to delete all Microsoft Word Document
ECHO Press CTRL+C to abort or simply press a key to continue.
Now when you execute this batch program, we get the following output:
WARNING: Going to delete all Microsoft Word Document
Press CTRL+C to abort or simply press a key to continue.
Press any key to continue . . .
The batch file program actually asks the user if he wishes to continue and gives the user the option to abort the process. Pressing CTRL+C cancels the batch file program(CTRL+C and CTRL+Break bring about the same results)
Terminate batch job (Y/N)?y
After this you will get the DOS prompt back.
Important: Say you have saved a batch file in the c:\name directory. Now when you launch command.com the default directory is c:\windows and in order to execute the batch file program stored in the c:\name directory you need to change the directory and go to c:\name.This can be very irritating and time consuming. It is a good practice to store all your batch programs in the same folder. You can run a batch file stored in any folder(Say c:\name) from anywhere(even c:\windows\history) if you include the folder in which the batch file is stored (c:\name)in the AUTOEXEC.BAT file, so that DOS knows which folder to look for the batch program.
So simply open c:\autoexec.bat in Notepad and append the Path statement to the
following line[c:\name is the folder in which all your batch files are stored.]:
Autoexec.bat runs each time at startup and DOS knows each time, in which directory to look for the batch files.
