compressing/zipping or uncompressing/unzipping files on hpux

[Shivkumar]

Dear Sirs,

What are the various commands available for compressing/zipping or unzipping/uncompressing
the files ?

Which one of them can be used for compressing or uncomprssing directories also ?

Thanks,
Shiv

Hi Shiv:

To compress and uncompress you can use 'compress(1)' or 'gzip'. See their manpages for more information. Another open source utility is 'bzip'.

As for compressig and uncompressing directories, you are really operating on all the files within the directory. The aforementioned utilities will do this too. Again, the manpages are your best friend!

hi shiv,

do not think that gzip was by default pre-install. if u require gzip:

http://hpux.connect.org.uk/hppd/hpux/Gnu/gzip-1.3.5/

as for compress, james is right to mention "man compress" for more info.

regards.

Hi Shiv,

You can use gzip which comes with HP-UX by default, Location : /usr/contrib/bin/gzip

Uncompressing, You can use gunzip or gzip -d
Location : /usr/contrib/bin/gunzip

Or, you can use jar -xvf to unzip files.

Hi Shiv,

You can use gzip, gunzip, zcat utilities to perform compress & expanding operations on hp ux. Please see the man pages for the same.

hi shiv,

concerning gzip, note that you will need to patch to the gzip 1.2.4 for it to support files greater than 4GB.

However, gzip cannot compress several files into a single archive directly! You will first have to create a tar file then compress it:
for GNU tar: gtar cvzf file.tar.gz filenames
for any tar: tar cvf - filenames | gzip > file.tar.gz

Alternatively, you can use zip, PowerArchiver 6.1, 7-zip or Winzip. The zip format allows random access to any file in the archive, but the tar.gz format usually gives a better compression ratio.

hope this helps too!

is winzip available on hpux ?

[Joseph Loo]

hi shiv,

winzip as its first 3 letters imply is for windows only.

Hello Shiv, for unzipping .zip files, you can use jar utility which is part of Java SDK on HP-UX.

# /opt/java1.4/bin/jar -xvf

hi again,

sorry for the confusion. winzip is for windows environments only.

You may try zip from http://www.info-zip.org/pub/infozip/

Also know as Info-ZIP, its purpose is to provide free, portable, high-quality versions of the Zip and UnZip compressor-archiver utilities that are compatible with the DOS-based PKZIP by PKWARE, Inc.

hope this helps too!

Hi Shiv,

Also a final thought,

You can use tar/pax/cpio etc , before using the compression tool, it will archived the files and then compress the file into a single file.

Ex:
# cd /mydir
# tar -cvf mydir.tar *
# gzip mydir.tar mydir.tar.gz

To uncompress:
------------
# cd dest_dir
## copy the source file mydir.tar.gz to dest_dir

# gunzip mydir.tar.gz
# tar -xvf mydir.tar

And you are done.

Hope this will help,

cheers,
Raj.
