Cutting down or splitting a file to several smaller pieces have great benefits. A large file split into several smaller files can easilly fit in a CD or floppy disk or even transferred over the network. Splitting the file is possible using the split command.
Below is an example on how to use the split command:
Using split on a 5.3MB image.iso file:
split -b 1400k image.iso
It will generate 4 files with the following file sizes:
To recreate the file, the cat command can be
cat xa* > new-image.iso
The split and cat commands are provided by the coreutils package. Once the new new-image.iso file is restored, its possible to delete the other split files.
Note: To verify that the file has been correctly restored, use the command md5sum before and after splitting the file. Syntax:
