NAME

znew -- convert compressed files to gzipped files

SYNOPSIS

znew [-ftv9K] file ...

DESCRIPTION

The znew utility uncompresses files compressed by compress(1) and recom- presses them with gzip(1). The options are as follows: -f Overwrite existing `.gz' files. Unless this option is specified, znew refuses to overwrite existing files. -t Test integrity of the gzipped file before deleting the original file. If the integrity check fails, the original `.Z' file is not removed. -v Print a report specifying the achieved compression ratios. -9 Use the -9 mode of gzip(1), achieving better compression at the cost of slower execution. -K Keep the original `.Z' file if it uses less disk blocks than the gzipped one. A disk block is 1024 bytes.

SEE ALSO

gzip(1)

CAVEATS

The znew utility tries to maintain the file mode of the original file. If the original file is not writable, it is not able to do that and znew will print a warning. DragonFly 5.3 August 1, 2003 DragonFly 5.3 ZNEW(1) 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; implies -t.

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. ZNEW(1)
