</div>Ok, James, believe it or not we are a little closer to getting this<br>
done.<br>
<br>
First point, sha1 and sha1sum are different commands. You can discover<br>
that for yourself by doing:<br>
<br>
$man sha1<br>
$info sha1<br>
$man sha1sum<br>
$info sha1sum<br>
<br>
The above can also be executed in root.<br>
<br>
Ok. Obviously, sha1sum did not work in user mode; execute the sha1sum<br>
command in root mode. Keep in mind that in Linux, there exist a few<br>
commands which can only be executed from within the directory where<br>
their binaries exist which means you have to know where those<br>
directories are. The short-cut is to invoke the root mode using the<br>
- flag which tells root that all commands throughout the entire<br>
directory tree in Linux are available to you as though they were in<br>
the same top-level directory and available to be immediately executed.<br>
The sequence to invoke this from user mode is the following:<br>
<br>
[aguila@arakus ~]$ su -<br>
Password:<br>
[root@arakus ~]#<br>
<br>
For clarification, the user mode and root mode should have different<br>
passwords as a way of maintaining clarity for Linux and yourself which<br>
account (root or user) one is using at any one time.<br>
<br>
Once you are in root mode try executing the sha1sum again. It should<br>
work without difficulty. Make sure that the sha1sum value produced on<br>
the .iso exactly matches the sha1sum value reported by the vendor.<br>
<br>
Remember it doesn't matter which shell you are using -- bash, ksh, csh,<br>
ash -- what matters is that you execute the root mode, as you have<br>
demonstrated that sha1sum cannot be executed from within user mode.<br>
<br>
Remember the short-cut I explained above.<br>

All the best...<br>
