Batch Files – Repeat certain tasks with a click

dos_command_prompt_batch_file

Batch file is a file which holds a list of commands or instructions that are executed once the batch file is executed. Basically the commands are DOS commands that are executed as if they were executed one by one on the command prompt. Batch files are of great help when you need to repeat a certain task many times. You can just specify what is to be done and it will be done when that batch file is executed.

Before moving further, you must be familiar with DOS because in this post I am going to explain only about batch files. To learn more about DOS commands, check out this link : Ms DOS help and commands

What it can do?

The limiting factor is you and the DOS itself i.e. What we want to do and can it be done through DOS. Not every program supports command line version (it can't be executed in the command prompt).

Example #1 (Open Multiple Applications)

You need to open up different set of applications depending on what you intend to do. Instead of clicking their icons one by one, you can save time by creating a batch file. For example: If I am in a mood of browsing internet while listening to songs, I can create a batch file with the following content:

start /max C:\Progra~1\Mozill~1\firefox.exe start /min C:\Progra~1\Google\Google~1\googletalk.exe start /min C:\Progra~1\Window~2\wmplayer.exe

Start command is used to start window applications. For more info about this command, type start /? at the command prompt. Here, I have assumed that all the programs are installed in their default folder. If you have installed them somewhere else, then make changes accordingly.

Example #2 (Copy files)

You need to copy all the files or certain files whenever you insert a CD/DVD/Pen drive, then you can create a batch file with the following content:

xcopy h:\*.* d:\docs\ /s

It is assumed that h:\ is your source drive (CD/DVD drive or pen drive) and you want to copy all the files to the docs folder residing on D drive.

xcopy h:\*.mp3 d:\songs\ /s

It is assumed that h:\ is your source drive (CD/DVD drive or pen drive) and you want to copy all the mp3s to the songs folder residing on D drive. Again, type xcopy /? at the command prompt for more about this command.

Example #3 (Delete Junk Files)

Following file types are considered as junk files : .~ ~. *.??~ *.--- *.tmp *._mp *.old *.bak *.syd *.chk *.gid mscreate.dir *.dmp 0???????.nch

You can make a batch file that scans for them and deletes them with the following content:

del c:\*.~* /s /q del c:\~*.* /s /q del c:\*.??~ /s /q del c:\*.--- /s /q del c:\*.tmp /s /q del c:\*._mp /s /q del c:\*.old /s /q del c:\*.bak /s /q del c:\*.syd /s /q del c:\*.chk /s /q del c:\*.gid /s /q del c:\mscreate.dir /s /q del c:\*.dmp /s /q del c:\0???????.nch /s /q del c:\windows\temp\*.* /q del c:\temp\*.* /q del d:\*.~* /s /q del d:\~*.* /s /q del d:\*.??~ /s /q del d:\*.--- /s /q del d:\*.tmp /s /q del d:\*._mp /s /q del d:\*.old /s /q del d:\*.bak /s /q del d:\*.syd /s /q del d:\*.chk /s /q del d:\*.gid /s /q del d:\mscreate.dir /s /q del d:\*.dmp /s /q del d:\0???????.nch /s /q

Add commands for other partitions in a similar fashion. Again, type del /? at the command prompt for more about this command.

Example #4 (Defagment and Shutdown the computer)

You can make a batch file that defragments the drive you specify and then shutdown the computer. Here is what you need to have it :

defrag c: defrag d: shutdown /s /t 10 /c "Defragmentation Complete !"

Add commands for other drives too. Shutdown command shutdown the computer. Again, type shutdown /? at the command prompt for more about this command.

To know more about any command, type command name followed by /? at the command prompt.

    could create a batch which directly scanning , detecting and deleting files.
    Scan, detect then delete the file: batch files.
    Thanks

      @Alphonse
      Can you explain a bit more what you want?
      A command like

      del c:\*.dmp /s /q

      will actually search for all files with extension dmp including the sub-directories because of the switch /s. Switch /q just puts in quiet mode.
