problem to uncompress

[JorgePablo]

Hi, i´m trying to uncompress a file. When i run the command "tar xvf hpux-11.16.002.tar" and "tar xvf hpux-11.16.002.tar.gz", in both case the result was:

directory checksum error

I searched in the forum but i didn't found a answer to my case.

Thanks!!!

      type tar
      which tar

   I wouldn't have expected plain "tar" to cope with ".tar.gz", but I
don't get out much these days.

   What made this archive?  You might do better using GNU "tar".  Those
"././@LongLink" things are used by GNU "tar" to encode file names which
are longer than 100 characters (the limit in old "tar" programs).

> directory checksum error

   That's a pretty uninformative error, often emitted by a "tar" program
which got lost.  It can be caused by a truncated archive, or by a defect
in the "tar" program.

[Bill Hassell]

As Steven said, standard HP-UX tar does not process gzip (.gz) files at all. To unpack and untar on one line, use gzcat like this:

gzcat hpux-11.16.002.tar.gz| tar xvf -

If you still get a checksum error, see if a simple listing fails:

gzcat hpux-11.16.002.tar.gz| tar tvf -

Be sure to include the minus - at the end.

If you still get a checksum error, make sure that the file (downloaded from someplace) was transferred in binary form. If the download was ftp and you were using a PC somewhere in the middle, the option to translate to ASCII text may have been enabled. If you can, use HP-UX to download the file and specify PASSIVE and BINARY before transferring.

[Steven Schweda]

> To unpack and untar on one line, use gzcat like this:

   I'm old-fashioned enough not to expect "gunzip" and "gzcat" to be
installed properly (along with plain-old gzip), so I (still) use
"gzip -dc" instead of "gzcat":

      gzip -dc whatever.tar.gz | tar xf -

   I find that the "v" option causes too many error messages to scroll
away and get lost.  (Of course, "v" is what revealed the "././@LongLink"
things here, so it's not all bad.)

> If you still get a checksum error, see if a simple listing fails:

   I'd expect both to fail if either fails.  I'd bet that the same code
reads the archive, either way.

   Still true.  Those "././@LongLink" things things do not represent real files
(so they should not be extracted into real files), and those "cannot
create" errors are what happens when paths longer than the 100-character
limit are truncated in the directory part of the path.  Note that the
name shown is exactly 100 characters long.  The "126 bytes" in the
preceding "././@LongLink" message is the real length of the (whole)
path.

   What you're _not_ seeing in those messages are warnings about the
erroneous file names which you're getting when when paths longer than
the 100-character limit are truncated in the file-name part of the path.
Those _can_ be created, but they're wrong.

> If you still get a checksum error, [...]

   I'd bet (a small amount) that the (compressed) archive is ok, but it
uses "tar" features which are not handled well by HP-UX "tar".  If the
compressed archive were corrupt, then I'd expect a complaint from
gzip/gzcat before one from "tar".  The easy (and most useful) test would
be to try GNU "tar".  (Or some other, more competent "tar" program.)

[JorgePablo]

i started again, and compressed the folder in a hpux system (before i had did in a redhat), after i copied the tar.gz to a hpux system but when i wanted to uncompress the file the system didn't find the gzcat. Now i'm going to install it and try again.

to compress the folder i used the command tar cf - HPUX-11.16.002 | gzip -c > hpux-11.16.002.tar.gz

[Bill Hassell]

>> system didn't find the gzcat...

The location for gzip and gzcat is /usr/contrib/bin. The shell will 'find' executables based on the current content of $PATH which you would edit /etc/PATH to add common locations. But you can use gzip -dc to accomplish the same task.

However, HP-UX has a very primitive version of tar and as Steven points out, there appear to be long filenames (more than 100 characters) in the directory you are using.  HP-UX tar cannot handle long filenames (see the man page for tar). You must install gtar (GNU tar) if you are exchanging files with Linux where many commmands  have been enhanced with GNU features.
