Are you worried of transferring or uploading large files over a network, then worry no more, because you can move your files in bits to deal with slow network speeds by splitting them into blocks of a given size.<\/p>\n

In this how-to guide, we shall briefly explore the creation of archive files and splitting them into blocks of a selected size. We shall use\u00a0tar<\/code>, one of the most popular archiving utilities on Linux and also take advantage of the\u00a0split<\/code>\u00a0utility to help us break our archive files into small bits.<\/p>\n

\"Create<\/a><\/p>\n

Create and Split tar into Multiple Files or Parts in Linux<\/p>\n<\/div>\n

Before we move further, let us take note of, how these utilities can be used, the general syntax of a\u00a0tar<\/code>\u00a0and\u00a0split<\/code>\u00a0command is as follows:<\/p>\n

# tar options archive-name files \r\n# split options file \"prefix\u201d\r\n<\/pre>\n
Let us now delve into a few examples to illustrate the main concept of this article.<\/p>\n
Example 1<\/strong>: We can first of all create an archive file as follows:<\/p>\n
$ tar -cvjf home.tar.bz2 \/home\/aaronkilik\/Documents\/* \r\n<\/pre>\n
\n
\"Create<\/a><\/p>\n
Create Tar Archive File<\/p>\n<\/div>\n
To confirm that out archive file has been created and also check its size, we can use\u00a0ls command<\/a>:<\/p>\n
$ ls -lh home.tar.bz2\r\n<\/pre>\n
Then using the split utility, we can break the\u00a0home.tar.bz2<\/code>\u00a0archive file into small blocks each of size\u00a010MB<\/code>\u00a0as follows:<\/p>\n
$ split -b 10M home.tar.bz2 \"home.tar.bz2.part\"\r\n$ ls -lh home.tar.bz2.parta*\r\n<\/pre>\n
\n
\"Split<\/a><\/p>\n
Split Tar File into Parts in Linux<\/p>\n<\/div>\n
As you can see from the output of the commands above, the\u00a0tar<\/strong>\u00a0archive file has been split to four parts.<\/p>\n
Note<\/strong>: In the\u00a0split<\/strong>\u00a0command above, the option\u00a0-b<\/code>\u00a0is used to specify the size of each block and the\u00a0\"home.tar.bz2.part\"<\/code>\u00a0is the prefix in the name of each block file created after splitting.<\/p>\n
Example 2:<\/strong>\u00a0Similar to the case above, here, we can create an archive file of a\u00a0Linux Mint ISO<\/strong>\u00a0image file.<\/p>\n
$ tar -cvzf linux-mint-18.tar.gz linuxmint-18-cinnamon-64bit.iso \r\n<\/pre>\n
Then follow the same steps in\u00a0example 1<\/strong>\u00a0above to split the archive file into small bits of size\u00a0200MB<\/code>.<\/p>\n
$ ls -lh linux-mint-18.tar.gz \r\n$ split -b 200M linux-mint-18.tar.gz \"ISO-archive.part\"\r\n$ ls -lh ISO-archive.parta*\r\n<\/pre>\n
\n
\"Split<\/a><\/p>\n
Split Tar Archive File to Fixed Sizes<\/p>\n<\/div>\n
Example 3:<\/strong>\u00a0In this instance, we can use a\u00a0pipe<\/strong>\u00a0to connect the output of the\u00a0tar<\/strong>\u00a0command to split as follows:<\/p>\n
$ tar -cvzf - wget\/* | split -b 150M - \"downloads-part\"\r\n<\/pre>\n
\n
\"Create<\/a><\/p>\n
Create and Split Tar Archive File into Parts<\/p>\n<\/div>\n
Confirm the files:<\/p>\n
$ ls -lh downloads-parta*\r\n<\/pre>\n
\n
\"Check<\/a><\/p>\n
Check Parts of Tar Files<\/p>\n<\/div>\n
In this last example, we do not have to specify an archive name as you have noticed, simply use a\u00a0-<\/code>\u00a0sign.<\/p>\n
How to Join Tar Files After Splitting<\/h3>\n
After successfully splitting tar files or any large file in Linux, you can join the files using the\u00a0cat command<\/a>. Employing\u00a0cat<\/strong>\u00a0is the most efficient and reliable method of performing a joining operation.<\/p>\n
To join back all the blocks or tar files, we issue the command below:<\/p>\n
# cat home.tar.bz2.parta* >backup.tar.gz.joined\r\n<\/pre>\n
We can see that after running the\u00a0cat command<\/a>, it combines all the small blocks we had earlier on created to the original tar archive file of the same size.<\/p>\n
Conclusion<\/h3>\n
The whole idea is simple, as we have illustrated above, you simply need to know and understand how to use the various options of\u00a0tar<\/code>\u00a0and\u00a0split<\/code>\u00a0utilities.<\/p>\n
