znew − recompress .Z files to .gz files
znew [ -ftv9PK] [ name.Z ... ]
The Znew command 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). | ||
|

Use pipes for the conversion to reduce disk space usage. | ||

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.
