Use the split command to carve up a large file into multiple pieces, and put them back together again with cat. Use md5sum to double check your results:
split -n 2 bigfile.tar.bz2 mkdir tmp mv bigfile.tar.bz2 tmp ls xaa xab cat xa* > bigfile.tar.bz2 md5sum bigfile.tar.bz2 08d860e55381aa87b2084449589d2dce bigfile.tar.bz2 md5sum tmp/bigfile.tar.bz2 08d860e55381aa87b2084449589d2dce tmp/bigfile.tar.bz2 |
You can also re-assemble these files using copy on Windows:
copy /b x* > bigfile.tar.bz2 |
