A simple way to check MD5sum

[bitsnpcs]

When changing from Windows to Linux Lite, you can in Windows use, WinMD5 free, to verify the download.

[firenice03]

If Vista and newer - Powershell should be installed by default, you can run the below command to check the MD5 checksum.. May alleviate the need to download a tool so you can dive right into a LL install  8) LOL

Its in tutorials as well: https://www.linuxliteos.com/forums/tutor.../#msg22470

Command to paste into Powershell:

Code:

if ( $($(CertUtil -hashfile C:PATH_to_FILE\File_name.iso MD5)[1] -replace " ","") -eq "PASTE_HASH_between_quotes" ) { echo "ok" }

CATH_to_FILE\File_name.iso -- The full path and the .iso file
"PASTE_HASH_between_quotes" -- Paste the supplied hash

If the hash checks out it returns an ok.. If not it will be blank...

Appreciate the help. Unsure why is not default on Windows 10 for me. So I had used the tool.

Name: Checksum
Description: Calculates  checksum.
Command: /usr/scripts/checksum %f
Pattern: *
Appearance: Check all the boxes except Directories

save the script as checksum
make executable
copy the file to /usr/scripts

I find the script rather useful. I've modified it to allow users to select a file just by launching the script. If the custom action in Thunar is configured, it will allow users to right-click and select files without prompting to browse for the file.

Extract and move the extracted files to their respective locations.

/usr/scripts/checksum
/usr/share/applications/checksum.desktop

Here is what it looks like:











Cheers!

That's an exciting way of adding it to a GUI through Thunar.

On LinuxLite, when I've needed to check MD5 (or other hash sums) I've just gone for a simple approach and used the command line with the built-in md5sum function (or sha1sum or sha256sum depending what function I want to use). It has worked well for me when checking copied or downloaded ISO's against original. I haven't used it for anything more advanced than that though.

I do like the addition to Thunar that you mentioned since it would allow the function to always just "be there" as an option for doing checksum of any file via GUI, which definitely is helpful. Thanks for the tutorial.

A month ago I switched the script to yad. I will add it to my repo so it can be easily installed. It creates the Thunar contextual menu option on install too and adds an option to copy the final sum to clipboard.

Hi, community.

[member=378]misko_2083[/member] and [member=6629]ralphy[/member],  this is great script. Thank you.

I do known not much about shell scripting, but I modify this checksum script for hash check, such as in gtkhash application.

Any improvement is welcome.

I am sorry by bad English language use; I am learning, yet..
