1. Create a 10MB file named as dummy.

• dd if=/dev/zero of=dummy bs=1024k count=10

2. Use the split command to break the file into 1MB pieces.

• split -b 1024k dummy dummy-part-

3. The file will be broken into pieces starting with the file name dummy-part-.
 

4. If you want to merge the pieces, use the cat command.

• cat dummy-part* > merged

Done =)
