stdin2file

A kind of tee-like program which writes stdin to file, and optionally compresses it using multiple threads.

Installation

Archives of precompiled binaries are available for Linux.

Other way is to clone project and compile it yourself.

Usage

stdin2file 1.2
hugruu <[email protected]>
Write from stdin to file(s), optionally compresses it using given algorithm

USAGE:
    stdin2file [OPTIONS] --chunk <chunk> --output <output>

OPTIONS:
    -c, --chunk <chunk>            Maximum size of single file size [MB]
    -e, --execute <execute>        Command to execute (instead of stdin) - CURRENTLY UNSUPPORTED
    -h, --help                     Print help information
    -m, --max-files <max-files>    Number of rotated files
    -o, --output <output>          Output file
    -s, --compress <compress>      Compression algorithm [possible values: xz, gz]
    -V, --version                  Print version information

Examples

Copy stdin to 5 rotating files, each 1 MB before compression, and compress them:

command | stdin2file -c 1 -m 5 -o test -s xz

Split 10 MiB text file using above settings:

base64 /dev/urandom | head -c 10000000 | stdin2file -c 1 -m 5 -o test -s xz

This will result in 5 files:

$ ls -la
total 3600

-rw-rw-r-- 1 gruszeck gruszeck 806532 Feb  5 18:14 test.6.xz
-rw-rw-r-- 1 gruszeck gruszeck 806952 Feb  5 18:14 test.7.xz
-rw-rw-r-- 1 gruszeck gruszeck 806504 Feb  5 18:14 test.8.xz
-rw-rw-r-- 1 gruszeck gruszeck 433092 Feb  5 18:14 test.9.xz

Possible improvements

• Add support for lzma, gzip or other algorithms
• Pass command as argument instead of pipe
• Add pipeline
