znew

ZNEW(1) 						      General Commands Manual							   ZNEW(1)

NAME

       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.
