NAME
gznew - recompress .Z files to .gz files SYNOPSIS
gznew [ -ftv9PK] [ name.Z ... ] DESCRIPTION
gznew 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 SEE ALSO
gzip(1), gzmore(1), gzdiff(1), gzgrep(1), gzforce(1), gzexe(1), compress(1) BUGS
gznew 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. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWgzip | +--------------------+-----------------+ |Interface Stability | External | +--------------------+-----------------+ NOTES
Source for gzip is available in the SUNWgzipS package. GZNEW(1)
