Windows Command Line Tricks

1. Join multiple mp3 files
Usually you require some software to join the mp3 files.
Here’s a nice trick that otherwise would require some software to perform. You can join multiple mp3 files to form a single mp3 file. Simply move to the folder in command line where mp3 files are stored that you want to combine and run the command

copy /b *.mp3 newfile.mp3

The wildcard *.mp3 will combine all mp3 files to form a newfile.mp3 file. You can control which files are combined using wildcard parameters.

2. Use previously entered Command
Just typed a long command moments ago and need to run that again but the effort involved to type again is making you sick! But don’t worry as command line keeps track of your previously entered commands which are accessible by pressing F7 key.

Command History

Alternatively you can use Up Arrow key to use earlier commands you used.

F1 & F2 also offer similar kind of functionality but in a different way, try them out.

3. Over Hide your files
Apart from normal hiding properties of Windows Graphical Interface, You can over hide your files using attrib command. Then after files will not be visible even if you use tools-> folder option-> View-> Show hidden files and folders.
Use the command

attrib +s +h pathtofile
for example, attrib +s +h E:\songs\abc.3gp

to over hide a file. Replace + symbol with - to remove over hidden attribute from file.

4. Map a Drive Letter to a Folder
Most of the time, our hard drives get filled with huge amount of data folder, files etc that moving to a folder you occasionally use becomes a heck. However, there’s a dos command that lets you map a drive letter to a folder. e.g. to map the folder C:\windows to M drive use the command:

subst M: C:\Windows

However the mapped drive gets lost once you restart your pc, you can then create a batch file including the above command and schedule it to run at system startup.

5. Change colors of command Window
Perhaps you need to take a print out of dos window and don’t want to waste ink on black background of dos window. Windows command line provides a command to change background and text color of dos window in a snap.

Simply use color bf to change colors. b is the code for background color and f is code for text color. To know color codes type color /? at command line.

6. Run Multiple commands at once
Multiple commands can be concatenated using && and run at once with single press of Enter. Simply type in your commands and concatenate them with && at once.

e.g. color f8 && dir && time

would run all the three commands one after another with a single press of Enter.

7. Filter output of commands
Some commands like systeminfo provide a whole bunch of information about your pc but what if you need info only about updates installed or Processor or Virtual Memory. You can filter the output using find. Here’s how to get only updates list from systeminfo.

systeminfo | find "Update"

This will only show updates installed on your system.

8. Drag Drop Folder paths
No need to type in long folder paths at command line, simply drag n drop that file or folder from explorer onto command line window to copy its path.

Resolve Computer Blue Screen Problem

Blue screen of  death (BSOD)

One of  the worst  problems faced by a computer user,  is when a computer with Windows operating system installed on it has a system error and display an error message "Illegal operation" on a blue screen, and the computer has to be restarted to prevent damage to the computer. The computer then has to be restarted, and all the work that was being done is lost.

Unlike startup errors which are indicated by a beeping sound , the blue screen of  death (BSOD) can occur at any time when you are working on your computer, without any warning. For example, it can occur when you are moving data between 2 folders and the data will have just disappeared from your hard disk!

The common causes for the blue screen of  death and the solutions to fix it are as follows:

1. Device driver problems - when new hardware is added to the computer, the device drivers may not be compatible. Try to get the latest updated version of the device driver from the manufacturer website. If it still does not work, remove or uninstall the new hardware and check if the problem continues.

2. New software installed may also cause a problem, so uninstall any new software. Viruses and spy ware can also cause problems, so ensure that you have the latest version of  antivirus software installed and scan your computer regularly. How to  remove all spyware, adware  and  run a free antivirus program.

3. Hardware problems - Computer components like the CPU, fan, RAM start malfunctioning after some time, especially if you use your computer for more than 10 hours a day.  Computers with AMD Athlon CPU's generate more heat compared to Intel CPU's and so this problem seems to be more common with these computers.

4. A simple configuration change which I made, after which I never faced the problem of  Blue Screen of  Death.

   a) In most computers the RAM memory is shared between the system and graphics  - for example ,  for 128MB  , 96 MB is for the system and 32 MB is for graphics (default setting).  Reduce the memory for graphics to the minimum - 8 MB.

   b) Change the virtual memory settings.

My Computer ---->   Properties ----->Advanced ------> Performance -------> Advanced ---------> Virtual  Memory.

For paging file size, select custom file size , with initial size 500 MB and final size 1000 MB. Save the settings. You can increase the paging file size further according to the software programs you use.

5. If nothing works, you can always reformat your computer hard disk and reinstall the operating system and software.
