"| more" is an essential sub-command. It pauses at each screen, making large amounts of text easier to read.

help | more
type filename.txt | more

It saves from scrolling back up to find what you want, and losing your place.

Answer 10

Run dxdiag, a DirectX diagnostic tool. Apart from giving DirectX components installed on your system it also gives a system information summary. All information can be exported as a text file.

CIPHER: this is a good one to permanently delete files off the computer. Once a file is deleted, it is only marked as deleted and it won't truly be delted off the hard drive until it's overwritten with the information or you can run cipher and the location of where the file used to be to truly delete it from the hard drive.

Usage:

cipher /w:"drive letter":"folder name"  

Example:

 cipher /w:C: (to do all the C: drive.)

Years ago I started using sync.exe (for file cache flushing) from the NTinternals guys. I've been migrating that binary around for maybe a decade, and it still works. Their company got assimilated by Microsoft, but the binaries are still hanging around on the net if you search.

Answer 23

I've found Launchy to be a very useful tool for Windows. It lets you launch many programs that would normally be launched by clicking icons by typing a few keystrokes. There's also a version for Linux. It can be found at www.launchy.net, and is free and open-source.

For example, to open an Explorer window from anywhere, type Alt-space (the default Launchy hot-key) followed by "c:\" followed by Enter. You can run any program for which you have a Windows shortcut by typing a few characters from the name of the shortcut. For example: Alt-space "co" Enter brings up Control Panel. You can also do Google searches, open URLs in the browser, and many other things without taking your fingers from the keyboard.

Answer 24
