Re: gzip repair
Martin Not necessarily so. Perhaps gunzip figures.tar.gz Martin followed by tar -xvf figures.tar works out all right. I have tried that, I get a unexpected EOF error when gunziping With very large files, 500+M, used to get bad gzips all the time. I never trusted it, and always had to check the new .gz with gzip -l . Do not know how gzip performs now. Since I back-up with dump(1). Try to use bzip ( not sure about the name, but it is in non-free). It might perform better than gzip. Or, try to buffer(1) the data before gzip sees them, maybe that will help. I don't think Debian has buffer(1), but you can get it from a sunsite mirror. It would be nice to know if Debian has a program that only buffers, anyone knows? Ioannis Tambouras [EMAIL PROTECTED], West Palm Beach, Florida Signed pgp-key on key server.

gzip repair
Does anyone know if there exists a utility to try and repair dammaged gzip files? I have a tar.gz with 13 postscript files which were generated with an MSDOG graphics programme in the Dark Days, unforunately when I gunzip I get $ tar -xvzf figures.tar.gz -rw-r--r-- graeme/staff 23145 Apr 17 11:00 1996 fig1.ps -rw-r--r-- graeme/staff 848606 Apr 17 15:27 1996 fig10.ps -rw-r--r-- graeme/staff 11253 Apr 17 11:00 1996 fig11.ps -rw-r--r-- graeme/staff 1013152 Apr 17 11:00 1996 fig12.ps -rw-r--r-- graeme/staff 888283 Apr 17 11:00 1996 fig13.ps gzip: stdin: unexpected end of file tar: Unexpected EOF on archive file tar: Child returned status 1 I realise that fig13.ps is probably dead, but is there a way to get past the error and recover subsequent files?

Not necessarily so. Perhaps gunzip figures.tar.gz followed by tar -xvf figures.tar works out all right. I think some earlier version of tar or gzip didn't handle the situation correctly when piping between them. However one by one it worked anyway. Or are you sure that there ought to be more files in the archive file? Thanks, Graeme Zum-zum, MartinS.

Perhaps gunzip figures.tar.gz Martin followed by tar -xvf figures.tar works out all right. I have tried that, I get a unexpected EOF error when gunziping, so it's definately a corruption of the gzip file. There are definately 13 files in the tar archive. I even tried reading the binary into Emacs using the hexl mode, but to no avail. Thanks for the suggestion, though.
