znew1

Usage

Overview

The Znew command recompresses files from .Z (compress) format to .gz (gzip) format. If you want to recompress a file already in gzip format, rename the file to force a .Z extension then apply znew.

Options

-f

Force recompression from .Z to .gz format even if a .gz file already exists.

-t

Tests the new files before deleting originals.

-v

Verbose. Display the name and percentage reduction for each file compressed.

-9

Use the slowest compression method (optimal compression).

-K

Keep a .Z file when it is smaller than the .gz file; implies -t.
