NAME

gznew - recompress .Z files to .gz files

SYNOPSIS

gznew [ -ftv9PK] [ name.Z ... ]

DESCRIPTION

The Gznew 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 gznew.

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, gznew 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.
