znew - recompress .Z files to .gz files
znew [ -ftv9PK] [ name.Z ... ]
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.
|
-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. |
gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1)
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.
