Hasher equivalent for Linux/ Ubuntu

I am using Hasher in windows to check and compare file hashes. Is there something like that for Ubuntu. I need some thing with a GUI?

Thanks

 

I've been using GtkHash for some time - very good.

aigle,
I've been using this nautilus script called Hash Checker...

http://gnome-look.org/content/show.php/Hash Checker 3.9.9?content=129309

and its great and simple to use. It checks md5, sha1, and sha256. You just right-click on the file you wish to check the hash of....go to scripts...click on Hash Check...a box pops up with 3 check boxes (sha1, sha256, md5...default is md5). Its creator has automated the whole process for its "install", if you want to call it that. Most nautilus scripts are placed in the /home/user/.gnome2/nautilus-scripts folder.

Later...

Bob

 

Thanks.

Can anyone of these also compare hashes?

 

GtkHash will hash a string, a file, or a group of files, but I don't think it will compare file hashes.

It's in the Ubuntu repository-check it out.

Thanks.

Really it,s hard to find sometimes very basic software in linux. Comaring hash without a software is not a pleasant thing to do. I wish there was a software in linux to do that, Windows has doazens of such software.

 

You might check out hashmonster.sourceforge.net

I developed the application a while back but didn't think it would be of much interest to anyone so I never released the source. I just uploaded it a few moments ago after seeing your post. There aren't many features but for simple hash comparisons (md5 or sha1) it does the job. Just paste the hash to compare in the bottom text box, select a file or enter a file path in the top text box and then press the "generate and compare" button.

 

I know you want a GUI, i don't know of one. Maybe kavulix has the answer.

As a reference though, the reason i don't know of one is that i'm satisfied with the md5sum program.
On a terminal, you just

Code:

md5sum <filename>

and you'll get

Code:

<md5>  <filename>

To check if the MD5 is the same as another, you could

Code:

md5sum <filename> | grep <MD5 you want to compare>

If it's the same, the typical output is printed.

Code:

<md5>  <filename>

Otherwise, nothing is printed.

Alternatively, you can output the md5 number to a file, for example

Code:

md5sum filename > filename.md5

And to check, provided both filename and filename.md5 are on the same directory, cd into it and

Code:

md5sum -c filename.md5

(note that the md5 extension isn't actually needed).

If it's the same md5, the output will be

Code:

<filename>: OK

Otherwise:

Code:

<filename>: FAILED
md5sum: WARNING: 1 of 1 computed checksum did NOT match

 

Thanks, I will try it. Before I was using Hasher in wine.

 

Thanks a lot Pedro but why i should remember or write down so many commands when same thing can be done via GUI in shorter time with more ease.

 

Maybe it looks like a lot of commands, but it's actually pretty simple. Try them if you want.

Perhaps the only thing that may look "off" is the '| grep' part.
| pipes the output of a command before it, to the command after.

So, 'md5sum filename | grep <md5 number>', in parts:

- First, 'md5sum filename' outputs an md5 number and the file name on the same line. Usually, it would be printed on the terminal.

- But because we piped the output to grep (the '|' part), grep now handles that line and does what you told it to, which in this case is 'grep <md5 number>', which means, search for '<md5 number>'. If it finds it, it prints it. If not, nothing gets printed, because it didn't find it.

 

Hi, I wil still prefer GUI, sorry for that.
