Split a large file into smaller files and then integrate them to get the original file

Question

How do I split a 7GB (movie) file into smaller files of (say) 1GB, and then (in another Ubuntu computer) integrate them to get the original file (using just bash commands)?

To split:

split -b 1G -d bigfile bigfile-part

To join:

cat bigfile-part* > bigfile

+1 best method. I usually like to check that everything worked by running 'md5sum bigfile' before and after. – scottl Nov 10 '10 at 03:15

To split the file into 1024MBs, using a terminal:

split --bytes=1024m original_filename /destination/path/prefix

To get the original file:

cat /source/path/prefix* > original_filename
