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.
BUGS¶
If the -P option is used, znew 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.
