Uploading 10 small files is often more reliable than uploading one 10GB file. 1. The Basics: Splitting by Line Count
When splitting and rejoining critical files, always verify that the restored file is identical to the original using md5sum or sha256sum . Run sha256sum original_file before splitting. Run sha256sum restored_file after rejoining. If the hashes match, your data is perfect. Summary Table Description split -l 100 file Split by 100 lines per file split -b 50M file Split into 50MB chunks split -d file Use numeric suffixes (00, 01...) split -a 4 file Use 4-digit suffixes (0000, 0001...) cat x?? > file Rejoin files back together
Splitting files is useful in various scenarios:
