HP HP-UNIX How to zip/compress files in a folder?
Environment: HP-Unix Operating System B.11.31 U ia64

I have a folder with around 2000 files. There are some files which sizes are more than 8 GB. I need to compress all the files in the folder into a single file, so that I can transfer the file.

I tried with tar command, but the tar command is failing if the filesize is more than 8 GB.

Please advise me the efficient way of compressing / zipping all these 2000 files in a folder.

TAR does not compress. It creates archives.

You will need to use gzip first on all files, then pax to create a big archive, since on HPUX tar will not support READ of archives greater then 8GB (but i think it will create one tho Smilie )

Alternative to above is to install gnu tar on HPUX machine and use that directly with compression (-z switch).

Hope that helps.

Peasant.

It is usually better to first tar then gzip:
Example:
Code:
tar cf - /path/to/folder | gzip -c > folder.tar.gz

Or create one on a remote system
Code:
tar cf - /path/to/folder | gzip -c | ssh remote_system "cat > /destination/folder.tar.gz"

It is also possible to store a relative path (easier to re-locate during extraction)
Code:
cd /path/to && tar cf - folder | ...

or
Code:
cd /path/to/folder && tar cf - . | ...

Thanks for the reply.

But I can not use
Code:
 tar

as it skips the files which are greater than 8 GB.

Please suggest other than tar.

Maybe cpio does not have this limitation?
Code:
cd /path/to/folder && find . -print | cpio -o | gzip -c > folder.cpio.gz

Or to remote system
Code:
cd /path/to/folder && find . -print | cpio -o | gzip -c | ssh remote_system "cat > /destination/folder.cpio.gz"

To unpack a .cpio.gz file in the current directory, run
Code:
gunzip -c /destination/folder.cpio.gz | cpio -idm

Another alternative, with pax that is compatible with tar:
Code:
cd /path/to/folder && pax -wf - . | gzip -c > folder.tar.gz

To a remote system
Code:
cd /path/to/folder && pax -wf - . | gzip -c | ssh remote_system "cat > folder.tar.gz"

Java
we can't use cpio command, because it limited to 2GB as man page said:

Because of industry standards and interoperability goals, cpio does
not support the archival of files larger than 2 GB or files that have
user/group IDs greater than 60 K. Files with user/group IDs greater
than 60 K are archived and restored under the user/group ID of the
current process.

If you have multiple files which are in same format say csv, then you can navigate into the directory and issue the below command
Code:
zip -r zip_file_name *.csv

This will zip all csv files into a zip file by name zip_file_name
