ZNEW(1) User Commands ZNEW(1)

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
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; 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
permissions if chmod(1) does not support the --reference option.
