Create Multipart Zip Files In Linux

by Ron on May 12, 2009

Need to transfer a really large file but are worried that it will fail before completing?

Create a multi-part file using the split command, then join it on the remote server after it transfers. Example: Start with a zipped file (, then run…

split -b 10m someprefix-

That will take, chop it into 10MB pieces and name them “someprefix-aa, someprefix-ab, etc.” Run “man split” for all the options:

split -b number[ k|m ] [-a suffixlength] [filename [prefix] ]

If your file will be split into more than 52 pieces, you’ll need to change the number of suffix length. The default is 2 (a-z, twice).

After transferring the pieces to the remote server, re-assemble them with cat…

cat someprefix-aa someprefix-ab ... >
