Tar and Untar in HP UX

Tar utility can be helpful while taking a backup. Note that tar can preserve the file's permission and its mode.

For example, I have the following directory structure:

/home/oracle/himanshu/database
/home/oracle/himanshu/database/data
/home/oracle/himanshu/database/12.1.0



Create a tar archive

tar cvf database.tar /home/oracle/himanshu/database

If you want to include into your archive several different directories you might use the following command:

tar cvf database.tar -I include.lst

where the -I option specifies the name of a file with a list of directories and files that you want to include into your archive.

Also, it's possible to exclude certain files and directories from your archive:

tar cvfX database.tar exclude.lst -I include.lst


List an archive contents

tar tf database.tar


Extract from an archive

tar xvfp database.tar

Please note that everything will be extracted exactly at the same location from where it was taken. If some directories do no exist then they will be created.


Tar's options

c - add to the archive, using an absolute path
x - extract from the archive
t - read the contents of an archive
f - you work with a file, otherwise, it's a tape
p - preserve file's permissions and modes
v - verbose, display the result
-I - use an include list
X - use an exclude list
