Working on a program for a production machine, so updating things is not really an option. We tend to have to stick to what our major software provider uses, and right now thats RHEL4. So mktemp version is 1.5. Just a bit older. Will be interested in checking out the version that doesn't write to disk. Thanks for the help. Yeah thats redhat for you.

It's a known limitation I settled with when I've decided to write in in Bash. I'm planning to re-write it in Python and then there won't be any need to actually extract the files back to the disk. So if your interested I suggest checking the blog every once in a while. About the mktemp error, it looks to me that your using an old version of mktemp. I checked the script with mktemp 6.10.

Reason is the actual files can get very large and potential disk space problems... Also get an error "mktemp: invalid option -- -" this is on RHEL4.6 Thanks.

As far as I understand, "tarsum /dev/nst0" should work, that's if /dev/nst0 can be treated as regular tar file (which is what I understand). Otherwise, you should copy the tar out of the tape drive, to a temporary location and then use tarsum regularly. Hi Swami,

However I need to verify checksums of archives stored on magnetic tapes. Is there a way of using tarsum in this way? e.g. tarsum /dev/nst0 This is perfect for what I need.
