NAME
znew - recompress .Z files to .gz files
SYNOPSIS
znew [ -ftv9PK] [ name.Z ... ]
DESCRIPTION
The Znew command recompresses files from .Z (compress) format to .gz
(gzip) format. If you want to recompress a file already in gzip for-
mat, 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; implies -t.

BUGS
If the -P option is used, znew does not maintain the timestamp if
touch(1) does not support the -r option, and does not maintain permis-
sions if chmod(1) does not support the --reference option.
