When
we are having a very large file or directory to be copied or transferred from
one place to another, It would be good practice to create a tar file first and
then split the tar into small pieces of tar which could be easily copied or
transferred and then merged back as a single file in the target environment.
First, we must
compress the file with tar archiver.
Syntax: $ tar
-cvzf <archive-name>.tar.gz <source_file>
example: tar
-cvzf test.tar.gz /home/obiee12c/catalog
To Split:
This command file archive
our folder to *.tar.gz. We can use file instead of path to folder for the
argument. Then we will split up our file archive into small parts.
Syntax: $
split -b 1024M <archive-name>.tar.gz “parts-prefix”
example: $
Split -b 1024M test.tar.gz test.tar.part
-b 1024M will split the file
into 1 Gigabytes size of file. The “part-prefix” will give the prefix name of
our parts of file.
To
Merge/Join this file, we can use cat command.
$ cat test.tar.part* >
test.tar.gz
