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; 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)
