I'm looking for a way to compress a large file (~10GB) into several files that wont exceed 150MB each.

Any thoughts?

  • how about gzip. like you tagged question with!?! – Mitch Wheat Aug 18 '11 at 10:08

Compress single file

This will compress file /path/to/your/large/file and creates many files with the prefix compressed.gz in the current directory, each file with a maximum size of 150000000 bytes:

gzip -c /path/to/your/large/file | split -b 150000000 - compressed.gz

Uncompress single file

To uncompress the file resulting in the uncompressed file "/path/to/decrompressed/file" compressed using the command above use:

cat compressed.gz* | zcat > /path/to/decrompressed/file

split [OPTION] [INPUT [PREFIX] - split a file into pieces

Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'. With no INPUT, or when INPUT is -, read standard input.

SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
