znew - recompress .Z files to .gz files
SYNOPSIS
znew [ -ftv9PK] [ name.Z ... ]
DESCRIPTION
Znew 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).
-P Use pipes for the conversion to reduce disk space usage.
-K Keep a .Z file when it is smaller than the .gz file
SEE ALSO gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1)BUGS
Znew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option.
