I am having some trouble compiling a Solaris 10 DVD what utility can I use to verify a files MD5 checksum and after that how do I combine the five files into a single file.
General procedure for DVD download
The DVD image is broken into five parts. To create a usable image, you
* download the five component files,
* use a utility that understands the ZIP compression format to
unpack each file,
* use a utility that can verify a file's MD5 checksum to confirm
each file has
been successfully downloaded,
* combine these files into a single file,
* use DVD burning software and hardware to copy the ISO image to disk.
1. Download the following component files (listed with their MD5 check
You should verify each file has not been corrupted during its
download via an "mdsum check", which compares your downloaded
file against the checksum of the file on Sun's server. There
are various free utilities to do this available for all popular
operating systems. (In case you're already using a pre-release
version of the Solaris 10 OS, it's worth mentioning that its
built-in "digest" command includes this capability.)
2. Unpack each component file, using a command such as "unzip"
3. Combine the five parts into the DVD image; two examples of how to do
this are given.
Use the cat command to copy the files in the correct order
into a single file named "sol-10-GA-x86-dvd-iso.iso"
cat sol-10-GA-x86-dvd-iso-[abcde] > sol-10-GA-x86-dvd-iso.iso
Use the Copy command with the /b flag to copy the files in the
correct order into a single file named "sol-10-GA-x86-dvd-iso.iso"
copy /b sol-10-GA-x86-dvd-iso-a + sol-10-GA-x86-dvd-iso-b +
sol-10-GA-x86-dvd-iso-c + sol-10-GA-x86-dvd-iso-d +
Just as with the individual components, you should verify the file's md5 checksum:
You should now have one image ready to be burned to a DVD.
Use the software that supports your DVD burner to create a DVD using this image file (e.g. Roxio Easy Media Creator on a Windows system or the cdrw utility on a Solaris system). Make sure you use the kind of media supported by your DVD burner. There are DVD-R/DVD-RW as well as DVD+R/DVD+RW recordable DVDs. Not all DVD burners support both. Do not use DVD+R DL (dual layer) discs.
