Re: [Bug-tar] Difference between -z option and piping to gzip

[Jim Hefferon]

Sergey,

  You said:
   To solve the problem you have to pass the same option to the
   gzip instance invoked by tar. You can do so by declaring GZIP
   environment variable:

   export GZIP=-n
   tar cfz arch1 testfile && 
    sleep 90 &&
    tar cfz arch2 testfile &&
    diff arch1 arch2; echo $?

   Try this and you'll get two identical archives.

Thanks for your reply; I'll look into that.  (Presumably I can figure
out how to compile gzip for the ftp/bin directory with -n hardcoded.)

Thanks also for your work on GNU tar.  We rely on it every day.

Jim
