  • Why Use Command-Line Tools?
  • Microsoft Command-Line Tool Resources
  • Other Command-Line Tool Resources
  • Q/A
why use a command line over a gui
Why Use a Command-Line over a GUI?

1. Faster than the clickity-click counterpart

  • View the network configuration:
    • ipconfig /all
  • Find all VBScript files in the path:
    • where *.vbs
  • Append a “1” to every file in the current directory:

Why Use a Command-Line over a GUI?

2. In some cases you don’t have a choice

  • Create an entry in an Event Log
    • eventcreate /L Application /T Error /ID 777 /D "Error Will Robinson"
  • Redirect the default AD computers container to an alternate location
    • redircmp “ou=MyComputers,dc=rallencorp,dc=com”
  • Diagnose AD DNS configuration issues
    • dnslint /ad /s localhost /v

3. Enhances your remote management capabilities

  • Many of the new tools have a /S option for targeting a remote machine
    • systeminfo /S rallen-srv1
  • With Sysinternals psexec you can even run non-remoteable utilities remotely
    • psexec \\rallen-srv1 cmd /k dir c:\

4. Enables you to automate common/complex tasks

  • Simple batch scripts just contain commands to run in sequence
  • Disable all inactive computer accounts and send the results in an email (2 commands)
    • oldcmp -report -file inactive.html -disable -b "cn=computers,dc=rallencorp,dc=com“
    • blat inactive.html -to [email protected] -html
