NirCmd is a versatile command-line utility for Windows that allows users to perform a variety of tasks by executing simple commands. Developed by NirSoft, NirCmd can manipulate system settings, manage files, and automate tasks without the need for complex scripting. This tool is particularly useful for system administrators and power users who need to perform repetitive tasks efficiently.

Examples:

1. Download and Installation:

   To get started with NirCmd, you need to download it from the NirSoft website. Once downloaded, extract the contents of the ZIP file to a directory of your choice. There is no installation process; you simply run the executable file (nircmd.exe) from the command line.

2. Basic Command Execution:

   Open Command Prompt and navigate to the directory where nircmd.exe is located. You can execute a variety of commands using NirCmd. Here are some practical examples:

   • Mute/Unmute System Volume:

     To mute the system volume, use the following command:

     nircmd.exe mutesysvolume 1

     To unmute the system volume, use:

     nircmd.exe mutesysvolume 0

   • Turn Off the Monitor:

     You can turn off the monitor using the following command:

     nircmd.exe monitor off

   • Create a Shortcut:

     To create a desktop shortcut for Notepad, use:

     nircmd.exe shortcut "C:\Windows\System32\notepad.exe" "~$folder.desktop$" "Notepad"

   • Open the CD/DVD Drive:

     If you need to open the CD/DVD drive, use:

     nircmd.exe cdrom open D:

     Replace "D:" with the appropriate drive letter if necessary.

3. Advanced Usage:

   NirCmd supports a wide range of commands and parameters. For instance, you can automate tasks such as changing the display resolution, setting the system time, or even taking screenshots. Refer to the NirCmd documentation for a comprehensive list of commands and their usage.

4. Automating Tasks with Batch Files:

   You can automate tasks by creating batch files (.bat) that contain NirCmd commands. Here’s an example of a batch file that mutes the system volume and then opens Notepad:

   @echo off
   nircmd.exe mutesysvolume 1
   start notepad.exe

   Save the above script as a .bat file and run it to execute the commands sequentially.
