UNIX for Dummies Questions & Answers

I am trying to run an old script to modify an image file with a modified header to bypass the md5 check but it comes up with an error message. The image file is for use on a Expressgate SSD so that I can add sqx files to it. This is a link from where I got the script:- sierrasoftworks.com/expressgate]ExpressGate | Sierra Softworks

Ive narrowed down the error to this part of the script.

#Make new header and make new img DFI
openssl dgst -md5 -binary FILE.IMG >new-md5sum
cat header new-md5sum FILE.IMG > NEW_FILE.IMG
gzip -9 NEW_FILE.IMG
mv NEW_FILE.IMG.gz NEW_FILE.DFI

This is the error:
cat: header: No such file or directory

It appears the new-md5sum file is locked and I cant do anything with it. I assume that the script has a problem trying to access it I am using Ubuntu 11.10 in VMware. Any help to try and fix this would be much appreciated as I know very little about Linux. Thanks.

The error means exactly what it says it does: "No such file or directory". There's no file named 'header' in whatever directory you're in. If you want one, you'll have to put one in there.

The new-md5sum file is not "locked". Linux/UNIX will actually allow you delete files that are open, so whether it's in use is irrelevant. The error means exactly what it says it does, "no such file or directory". Whatever you're running simply can't find it. Maybe it's not running in the same place you put the file?

Where does that 'rm' message come from, anyway? That's not part of the script you posted.

These are the files Im working with that Ive added as attachments. This is the terminal printout after running DFI.sh. Original.DFI is the Expressgate SSD file.

You can edit the contents of the image by doing the following:

a) Change files in the directory you want to edit.
b) Create new packages by creating a new folder with the correct
package name and contents.
c) Type "exit" when done to apply changes.

File Integrity Checking
It is recommended that you patch the version file, this will enable file intergity checking on all files that you have added as well as allowing you to modify original files without causing SplashTop to fail.

Would you like to patch the version file? [y/n]: y

If the header is missing, I assume there is a problem with DVM-Header.exe ? Anyway Ive spent about 20hrs trying to sort but enough is enough. Thanks anyway.

Does this dvm program generate files? perhaps it's not really called 'header'.
