lrztar

wrapper for lrzip that simplifies compression of directories

TLDR

Archive and compress a directory with default LZMA compression

$ lrztar [path/to/directory]

Compress with LZO (fastest)

$ lrztar -l [path/to/directory]

Compress with bzip2

$ lrztar -b [path/to/directory]

Compress with gzip

$ lrztar -g [path/to/directory]

Compress with ZPAQ (best ratio, slowest)

$ lrztar -z [path/to/directory]

Specify output file

$ lrztar -o [path/to/output.tar.lrz] [path/to/directory]

Compress with verbose output and force overwrite

$ lrztar -v -f [path/to/directory]

SYNOPSIS

lrztar [lrzip-options] directory

lrztar is a wrapper for lrzip that simplifies compression of directories. It first creates a tar archive, then compresses it using lrzip's long-range compression algorithms. Output defaults to DIRECTORY.tar.lrz. lrztar accepts the same options as lrzip.

PARAMETERS

-l, --lzo

Use ultra-fast LZO compression

-b, --bzip2

Use bzip2 compression

-g, --gzip

Use gzip compression

-z, --zpaq

Use ZPAQ compression (best ratio, very slow)

-n, --no-compress

Only perform long-range redundancy reduction (no 2nd stage compression)

-o, --outfile FILE

Specify output filename

-p, --threads N

Number of processor threads

-f, --force

Force overwrite existing files

-v, --verbose

Increase verbosity (-vv for more)

-D, --delete

Delete source files after successful compression

CAVEATS

Default compression algorithm is LZMA. ZPAQ provides best compression ratio but is approximately 4x slower than LZMA. LZO offers bzip2-like ratios at near file-copy speeds.
