FCIV

[dedanna1029]

FCIV is a command-line utility for Windows to check the md5sum or sha1 of files. I use it to verify downloads of Linux .iso files to verify them, although this utility can be used for any file.

Its installation is simple, and it is easy to use even for the newbie to Windows. sha1, as most know, is the best way to verify a file, but md5sum is a quick off-the-cuff way to do it. I've used both with FCIV here:



Although the utility is not *officially* supported by Microsoft, they support it enough to put it up at their site, and host it as a download with installation instructions, and instructions on how to use it. It's the one thing Microsoft does right.

Everything you need for it, download, installation instructions, how to use it, the works is here.

Edit: **Limitations: For sha, it only verifies sha1. It doesn't verify sha256. There is Raymond's utility for that.

Thanks!
To make it work everywhere in the cmd window you can type:

Code: Select all

set path=%path%;c:\fciv

This will make it work without navigating to C:\fciv first.
This makes it possible to stand in the folder where your iso is and typing the command so that you do not have to specify that long path to it.

This will be gone after a reboot

To make it permanent

Select 'System' from the Control Panel, selecting the 'Advanced' tab, the 'Environment Variables' button and then finding the PATH
Add this at the end:

Code: Select all

;C:\fciv

PS this naturally means that you have extracted fciv to C:\fciv

You really should do this because you will forget where fciv is

After that you can simply do a

Code: Select all

fciv viking.iso

wherever you are (Or wherever that download is)

Thank you for that!

It might be possible to make it stick with a command in cmd
