====== BASH - Files - Split big files ======

To split big files, the **split** command can be used. 

For example to split a 400MB file named bigfile into 100MB chunk files named smallfile0*

<code bash>
split -b 100M -d --verbose bigfile smallfile

creating file 'smallfile00'
creating file 'smallfile01'
creating file 'smallfile02'
creating file 'smallfile03'
</code>

where:

  * **-b** is for byte size.
  * **-d** is for numeric suffixes.
  * **smallfile** is the prefix to be used.

The output is:

<code bash>
ls

bigfile smallfile00 smallfile01 smallfile02 smallfile03
</code>

To recover back the splitted files into a file named newbigfile:

<code bash>
cat smallfile0* > newbigfile
</code>
